19-3-2017 MIAMI, FLORIDA - BLUE JAY (Cyanocitta cristata)

The Blue Jay, a member of the Corvidae family, is a striking bird native to eastern North America. It is easily recognized by its vibrant blue plumage, white underparts, and distinctive blue crest. A black, U-shaped collar adorns its neck, with a black border trailing behind the crest. Both sexes are similar in appearance, and their plumage remains consistent throughout the year.

To identify a Blue Jay, look for the following characteristics: a size ranging from 22 to 30 cm (9–12 in) from bill to tail, a weight between 70–100 g (2.5–3.5 oz), and a wingspan of 34–43 cm (13–17 in). The crest on the head is a key feature, which the bird can raise or lower. The bird's blue coloration is most vibrant on the crest, back, wings, and tail, with a contrasting white face and off-white underside.

Blue Jays are adaptable and can be found in various habitats, including deciduous and coniferous forests, residential areas, and mixed woodlands with oaks and beeches. They are less common in denser forests and have adapted well to human activity.

This species is widespread across southern Canada and the eastern and central United States, extending as far south as Florida and northeastern Texas. Some populations in the northernmost parts of its range may migrate seasonally.

Blue Jays are known for their intelligence and curiosity. They are bold and aggressive, especially when defending their territory. They may mob predators and have been observed using mimicry to deter competition. Blue Jays are also known to cache food for later consumption.

The Blue Jay has a wide repertoire of vocalizations, including the familiar "jay" call. They can mimic the calls of hawks and are known for their loud, gull-like alarm call. Their "rusty pump" call is a quieter, squeaky sound used among individuals in close proximity.

Blue Jays form monogamous pair bonds and both sexes participate in nest building and rearing the young. Nests are typically built in trees at heights of 3 to 10 m (10 to 33 ft). Clutches consist of 2 to 7 eggs, which are blueish or light brown with darker spots. The young are altricial and stay with their parents for one to two months after hatching.

The Blue Jay can be confused with other jay species, but its distinctive coloration and crest make it relatively easy to distinguish.

The diet of the Blue Jay is primarily composed of seeds and nuts, such as acorns, as well as soft fruits, arthropods, and occasionally small vertebrates. They are known to hide food to eat later and are adept at using their strong bills to crack open nuts.

The Blue Jay is currently listed as Least Concern by the IUCN Red List of Threatened Species, indicating that it is not at immediate risk of population decline.

19-3-2017 MIAMI, FLORIDA - GREAT HORNED OWL (Bubo virginianus)

                                     

The Great horned owl (Bubo virginianus) is a large owl native to the Americas. It is an extremely adaptable bird with a vast range and is the most widely distributed true owl in the Americas. The Great horned owl is one of the earliest nesting birds in North America, often laying eggs weeks or even months before other raptorial birds.

The Great horned owl is a round-faced bird with a distinctive horn-shaped feather tuft on the crown of its head, which is darker than the rest of its head, promoting the overall camouflage. The owl possesses powerful, solid legs, feet, and claws. The Great horned owl has binocular vision due to its eyes, facing forward. The eyes of the horned owl are various shades of yellow. This bird can also be distinguished by the white colored patch on its throat. Black and brown stripes extend all over the white underbelly. The bill of the bird is black, surrounded by white or tan colored plumage. The plumage on their back is darker, covered with brown and black markings.

This owl is native to the Americas with its range, covering the greater part of North America, stretching to Central America, and reaching South America. The Great horned owl occurs primarily in woodlands and open fields, scattered throughout its range. However, the species can also be found in mangroves, grasslands, swampy and marshy areas as well as deserts. In addition, this bird occasionally inhabits human settlements, found throughout rural and urban areas.

These birds are solitary animals, socializing only for nesting. They usually roost by day in protected places such as a tree limb or a recess in a rock. Great horned owls are efficient nighttime hunters, though they are known to hunt in the daytime as well. Horned owls are non-migratory, remaining within the same area throughout the year. Some individuals may become "territorial floaters", not having a certain territory and constantly traveling through territories of other owls. These birds use hooting as a form of communication. Through hooting, they can search for mates during the mating season as well as set up territorial dominance.

19-3-2017 MIAMI, FLORIDA - EASTERN BLUEBIRD (Sialia sialis)

The eastern bluebird (Sialia sialis) is a small North American migratory thrush found in open woodlands, farmlands, and orchards.

The bright-blue breeding plumage of the male, easily observed on a wire or open perch, makes this species a favorite of birders. The male's call includes sometimes soft warbles of jeew or chir-wi, or the melodious song chiti WEEW wewidoo. It is the state bird of Missouri and New York.

The eastern bluebird is found east of the Rockies, southern Canada to the Gulf states, and southeastern Arizona to Nicaragua. The increase in trees throughout the Great Plains during the past century due to fire suppression and tree planting facilitated the western range expansion of the species. as well as range expansions of many other species of birds. From 1966–2015 the eastern bluebird experienced a greater than 1.5% annual population increase throughout most of its breeding and year-round ranges, with exceptions including southern Florida and the Ohio River valley.

Bluebirds tend to live in open country around trees, but with little understory and sparse ground cover. Original habitats probably included open, frequently burned pine savannas, beaver ponds, mature but open woods, and forest openings. Today, they are most common along pastures, agricultural fields, suburban parks, backyards, and even golf courses. Populations also occur across eastern North America and south as far as Nicaragua. Birds that live farther north and in the west of the range tend to lay more eggs than eastern and southern birds.

An isolated, insular subspecies of the eastern bluebird is found on Bermuda, and has a distinctive, brighter blue coloration compared to mainland populations. This population was formerly thought to have been predated the colonization of the islands (making it one of only three extant, resident pre-colonization Bermuda landbirds, alongside the Bermuda white-eyed vireo and gray catbird). However, analysis of fossil strata found no evidence for the existence of bluebirds on the islands prior to European colonization. Using simulations and molecular evidence, a 2013 study found that the Bermuda bluebirds likely descend from very small founder population from a single colonization event during the 1600s. This colonization event could either be a natural one by migratory individuals or an anthropogenic introduction by early settlers, who are known to have introduced several other eastern North American birds like the northern cardinal (Cardinalis cardinalis) to Bermuda very shortly after colonization. It is likely that the alteration to the islands' ecosystem due to the clearing of native forest facilitated this colonization by providing optimal bluebird feeding habitat, along with a lack of predators.

19-3-2017 BUTTERFLY WORLD, FLORIDA - MEXICAN LONGWING BUTTERFLY (Heliconius hortense)

Heliconius hortense, the Mexican longwing, Mexican heliconian or mountain longwing, is a heliconiid butterfly.

The basic color of the uppersides of the wings is black, with a vertical white band on the forewings and an horizontal red band on the hindwings. The undersides are dark brown, with a white band on the forewings and a few red spots at the base of the hindwings. The adults feed on pollens and live up to six months. Females usually lay yellow eggs singly on shoots of various host plants, mainly Passiflora species, of which caterpillars primarily feed.

Heliconius hortense occurs in eastern and western Mexico and from Honduras to Ecuador.

This species can be found in cloud forest from sea level to 2300 m.

The Mexican Longwing Butterfly is native to southern Mexico and northern Central America. It is sometimes called the Mountain Longwing although it is not found only in mountain areas. It looks similar to the butterfly shown on this page but HAS WHITE BARS ON THE FOREWING instead of pink and they have a particular pattern that differs a little from those shown.

They could also be hybrids of H. himera and the Small Postman.

They may also be a related mimic species or other heliconian hybrids that fly in the same regions.

19-3-2017 BUTTERFLY WORLD, FLORIDA - WESTERN TIGER SWALLOWTAIL (Papilio rutulus)

 Papilio rutulus, the western tiger swallowtail, is a swallowtail butterfly belonging to the Papilionidae family. The species was first described by Hippolyte Lucas in 1852.

Like the other tiger swallowtails, the western tiger swallowtail was formerly classified in genus Pterourus, but modern classifications all agree in placing them within Papilio.

This common species is present in western North America. The normal range of the western tiger swallowtail covers much of western North America, from British Columbia to North Dakota in the north to Baja California and New Mexico in the south. Individuals occasionally turn up east of this range; in eastern North America, though, it is replaced by the similar eastern tiger swallowtail, Papilio glaucus.

These butterflies are frequently seen in urban parks and gardens, as well as in rural woodlands and riparian areas.

19-3-2017 MIAMI, FLORIDA - PILEATED WOODPECKER (Dryocopus pileatus)

The Pileated woodpecker (Dryocopus pileatus) is a large woodpecker that live in forests of eastern North America. It is the largest extant woodpecker species in North America, with the possible exception of the Ivory-billed woodpecker, which the U.S. Fish and Wildlife Service has proposed be reclassified as extinct. It is also the third largest species of woodpecker in the world, after the Great slaty woodpecker and the Black woodpecker. "Pileated" refers to the bird's prominent red crest, from the Latin pileatus meaning "capped".

Pileated woodpeckers are mainly black with a red crest, and have a white line down the sides of the throat. Younger specimens tend to have less curved crests, or "mohawks" as some refer to them. They show white on the wings in flight. The flight of these birds is strong and direct, but undulates in the way characteristic of woodpeckers. Adult males have a red line from the bill to the throat; in adult females these are black.

19-3-2017 MIAMI, FLORIDA - CAROLINA WREN (Thryothorus ludovicianus)

The Carolina wren (Thryothorus ludovicianus) is a robust, cinnamon-brown bird that graces the eastern half of the United States, southern Ontario, and northeastern Mexico with its presence. This wren, the state bird of South Carolina, is the second-largest wren species in the United States, following the cactus wren. It measures approximately 12.5 to 14 cm in length, with a wingspan of 29 cm and a weight ranging from 18 to 23 grams. Males are typically larger than females, with a slight sexual dimorphism evident in their size.

The Carolina wren can be identified by its rich brown plumage, which is more chestnut on the rump and upper tail coverts. It has a distinctive white eyebrow stripe, a speckled gray and black ear covert, and a belly that transitions from gray to a warm buff color. The tail features dark bars, and the bird's legs are flesh-colored. The juvenile resembles the adult but has paler and softer plumage with buff-tipped wing coverts.

Carolina wrens favor dense cover in forests, farm edges, and suburban areas. They thrive in a variety of woodlands, including oak hardwoods, mixed oak-pine, and riparian forests. They are also commonly found in overgrown farmland and yards with thick shrubs and trees.

This species is resident in its range, with severe winters limiting its northern distribution. Favorable weather conditions can lead to a northward extension of their breeding range. They are found from southeastern Canada through the eastern United States to northeastern Mexico.

Carolina wrens are active and inquisitive birds, rarely staying still as they investigate their surroundings. They are generally inconspicuous, preferring to stay out of the open. Pairs maintain territories and stay together for several years, exhibiting strong pair bonds.

The male Carolina wren is a prolific singer with a repertoire of various phrases, often described as "teakettle-teakettle" or "cheery-cheery-cheery." Songs are sung throughout the year, except during harsh weather. Females do not sing but may have song control regions suggesting a capacity for song learning.

Carolina wrens are monogamous, usually mating for life. They build arch-shaped nests with a side entrance, using materials like dried plants, bark, and even snake sloughs. Nests are often in cavities or man-made structures. They can raise multiple broods in a season, with clutch sizes ranging from 3 to 6 eggs.

The Bewick's wren is the most similar species, being smaller with a longer tail and grayer-brown above. The white-browed wren, or Cabot's wren, is also similar but considered a separate species or subspecies by some.

The diet of the Carolina wren is primarily invertebrates, including beetles, true bugs, grasshoppers, and spiders. They also consume small lizards, tree frogs, and occasionally vegetable matter. They forage on or near the ground, probing bark crevices and leaf litter.

The Carolina wren is listed as Least Concern by the IUCN. Some populations have been affected by mercury contamination, which can impact reproductive success. They are also subject to brood parasitism by brown-headed cowbirds, which can affect the hatching success of their eggs.

17-3-2017 PARC DE NEGOCIS, BARCELONA - EUROPEAN GREENFINCH (Chloris chloris)

The European greenfinch, or simply greenfinch, is a small passerine bird belonging to the finch family Fringillidae. Exhibiting a predominantly green plumage with yellow accents on the wings and tail, the male is a vibrant sight, while the female and juveniles are more subdued with brownish tones. This bird measures approximately 15 cm in length with a wingspan ranging from 24.5 to 27.5 cm, resembling the size and shape of a house sparrow.

To identify the European greenfinch, look for its thick and conical bill, a characteristic of seed-eating birds. The male's plumage is a striking green with yellow flashes on the wings and tail, whereas the female and young birds are more muted with brownish backs. The male's display flight is akin to a butterfly, a dance to charm its mate.

The greenfinch favors woodland edges, farmland hedges, and gardens with dense vegetation for breeding. It nests in trees or bushes within these habitats.

This bird has a broad range across Europe, North Africa, and Southwest Asia. It is mainly sedentary, but some populations in the northernmost regions migrate southwards in colder months. The species has also been introduced to Australia, New Zealand, Uruguay, and Argentina.

The greenfinch is known for its social nature, often seen in flocks outside the breeding season. It exhibits a breeding season from March to June, with fledglings emerging in early July. The species is capable of producing multiple broods annually.

The song of the greenfinch is a delightful mix of trills and twitters, interspersed with distinctive wheezes, contributing to the rich tapestry of sounds in its natural environment.

The female greenfinch constructs the nest and incubates the eggs, typically laying 4-6 eggs per clutch. Eggs are incubated for about 13-14 days, with chicks being fed an insect larva-rich diet initially, followed by a seed paste as they grow.

The greenfinch can be confused with other finches, but its unique green and yellow plumage, along with its size and bill shape, usually set it apart.

Greenfinches have a varied diet consisting of seeds, berries, fruits, buds, flowers, and some arthropods. They forage in trees, bushes, and on the ground, adapting to available food sources.

The IUCN lists the European greenfinch as Least Concern, indicating a stable population despite some regional declines due to disease outbreaks.

17-3-2017 PARC DE NEGOCIS, BARCELONA - EUROPEAN SERIN (MALE) (Serinus serinus)

The European serin, or simply the serin (Serinus serinus), is a diminutive member of the finch family, Fringillidae. This sprightly bird is the smallest within its family, closely related to the Atlantic canary. It is characterized by its short tail and a length that spans a mere 11 to 12 centimeters. The serin's plumage is a tapestry of nature's palette, with upper parts dappled in dark-streaked greyish green and a conspicuous yellow rump. The underparts are a canvas of yellow breast and white belly, both adorned with heavy streaks.

When attempting to identify the European serin, look for the male's radiant yellow face and breast, which stand out against the greenish backdrop of its feathers. The male also boasts yellow wing bars and yellow tail sides, which can be quite helpful in distinguishing it from similar species. Both sexes share a buzzing trill of a song that resonates through their Mediterranean habitats.

The European serin is partial to open woodland and cultivated areas, often with a sprinkling of conifers. These environments provide the perfect backdrop for breeding and foraging.

This species has a breeding range that extends across southern and central Europe and into North Africa. Populations along the southern and Atlantic coasts tend to be resident, while those in the north are migratory, seeking warmer climates in southern Europe during the winter months.

Outside of the breeding season, the European serin is a sociable creature, forming flocks that may sometimes mingle with other finch species. It is an active and often conspicuous bird, its presence easily announced by its distinctive trill.

The serin's song is a distinctive buzzing trill, a sound that becomes part of the ambient music in regions where these birds are common.

The European serin weaves its nest within the shelter of a shrub or tree, where it lays a clutch of 3 to 5 eggs. The chosen breeding habitats are often areas of open woodland and cultivation, with a preference for some conifers.

The diet of the European serin is predominantly seeds, but it does not shy away from including insects during the breeding season, providing essential protein for its young.

The IUCN Red List categorizes the European serin as Least Concern, indicating that, for now, this species does not face any imminent threats to its survival.

17-3-2017 PARC DE NEGOCIS, BARCELONA - WHITE WAGTAIL (Motacilla alba)

The White wagtail is a slender bird with the characteristic long, constantly wagging tail of its genus. There are a number of other subspecies, some of which may have arisen because of partial geographical isolation, such as the resident British and Irish form, the pied wagtail M. a. yarrellii, which now also breeds in adjacent areas of the neighbouring European mainland. The Pied wagtail exchanges the grey colour of the nominate form with black (or very dark grey in females), but is otherwise identical in its behaviour. Other subspecies, the validity of some of which is questionable, differ in the colour of the wings, back, and head, or other features. Some rraces show sexual dimorphism during the breeding season. As many as six subspecies may be present in the wintering ground in India or Southeast Asia and here they can be difficult to distinguish.

White wagtails breed throughout Eurasia, only being absent in the Arctic. They also breed in the mountains of Morocco and western Alaska. These birds are residents in the milder parts of their range such as western Europe and the Mediterranean, but migratory in much of the rest of their range. Northern European breeders winter around the Mediterranean and in tropical and subtropical Africa, and Asiatic birds move to the Middle East, India, and Southeast Asia. Birds from the North American population also winter in tropical Asia. White wagtails occupy a wide range of habitats but are absent from deserts. They inhabit grasslands, seashores, rocky shorelines, sand beaches, tidepools, rivers, lakeshores, farmland, gardens, and parks. They are also often found in towns and villages. 

17-3-2017 PARC DE NEGOCIS, BARCELONA - LITTLE EGRET (Egretta garzetta)

The Little egret (Egretta garzetta) is small elegant heron in the family Ardeidae. As an aquatic bird, it feeds in shallow water and on land, consuming a variety of small creatures. At one time common in Western Europe, the Little heron was hunted extensively in the 19th century to provide plumes for the decoration of hats and became locally extinct in Northwestern Europe and scarce in the south. Around 1950, conservation laws were introduced in southern Europe to protect the species and their numbers began to increase.

The plumage of the Little egret is normally entirely white, although there are dark forms with largely bluish-grey plumage. In the breeding season, the adult has two long plumes on the nape that form a crest. These plumes are about 150 mm (6 in) and are pointed and very narrow. There are similar feathers on the breast, but the barbs are more widely spread.

16-3-2017 MONTE CORNA, VALENCIA - RED ADMIRAL BUTTERFLY (Vanessa atalanta)

Vanessa atalanta, the red admiral or, previously, the red admirable, is a well-characterized, medium-sized butterfly with black wings, red bands, and white spots. It has a wingspan of about 2 inches (5 cm). It was first described by Carl Linnaeus in his 1758 10th edition of Systema Naturae. The red admiral is widely distributed across temperate regions of North Africa, the Americas, Europe, Asia, and the Caribbean. It resides in warmer areas, but migrates north in spring and sometimes again in autumn. Typically found in moist woodlands, the red admiral caterpillar's primary host plant is the stinging nettle (Urtica dioica); it can also be found on the false nettle (Boehmeria cylindrica). The adult butterfly drinks from flowering plants like Buddleia and overripe fruit. Red admirals are territorial; females will only mate with males that hold territory. Males with superior flight abilities are more likely to successfully court females. It is known as an unusually calm butterfly, often allowing observation at a very close distance before flying away, also landing on and using humans as perches.

The forewing of this butterfly bears on a black ground an oblique vermilion bandand a group of white subapical spots. On the hindwing the larger portion of the distal margin is red, with a row of small black spots and at the anal angle an elongate blue spot. The underside is partly variegated with blue; the forewing is on the whole similar in markings to the upper, while the hindwing is brightly variegated and clouded, bearing black markings, of which those in the cell resemble a figure (on the left wing 18 or 98, on the right 81 or 89); in the middle of the costal area there is a pale patch and in the distal marginal area a row of ocellus-like spots. Sometimes, especially in the female, the red band of the forewing bearsa small white spot in the middle.

The red admiral is found in temperate regions of North Africa, North and Central America, Europe, Asia, and island regions of Hawaii, and the Caribbean.

15-3-2017 MONTE CORONA, VALENCIA - EURASIAN HUMMINGBIRD HAWKMOTH (Macroglossum stellatarum)

The hummingbird hawk-moth (Macroglossum stellatarum) is a species of hawk moth found across temperate regions of Eurasia. The species is named for its similarity to hummingbirds, as they feed on the nectar of tube-shaped flowers using their long proboscis while hovering in the air; this resemblance is an example of convergent evolution.

The hummingbird hawk-moth was first described by Carl Linnaeus in his 1758 10th edition of Systema Naturae. As of 2018, its entire genome and mitogenome have been sequenced.

The hummingbird hawk-moth is distributed throughout the northern Old World from Portugal to Japan, but it breeds mainly in warmer climates (southern Europe, North Africa, and points east). Three generations are produced in a year in Spain. There is evidence that the population in the British Isles is actively expanding its range, as numbers have been consistently increasing. In addition, it is believed that this population is becoming resident instead of migratory, as warmer temperatures due to climate change are allowing individuals to overwinter.

It is a strong flier, dispersing widely in the summer. However it rarely survives the winter in northern latitudes (e.g. north of the Alps in Europe, north of the Caucasus in Russia).

Moths in the genus Hemaris, also of the family Sphingidae, are known as "hummingbird moths" in the US, and "bee moths" in Europe. This sometimes causes confusion between this species and the North American genus.

Two or more broods are produced each year. The adult may be encountered at any time of the year, especially in the south of the range, where there may be three or four broods. It overwinters as an adult in a crevice among rocks, trees, and buildings. On very warm days it may emerge to feed in mid-winter. Unlike other moths, they have no sexual dimorphism in the size of their antennal lobes.

The glossy pale green ova (eggs) are spherical with a 1-millimetre (0.04 in) diameter. They are said to look like the flower buds of the host plant Galium, and that is where the female lays them. They hatch 6 to 8 days after laying. Up to 200 eggs may be laid by one female, each on a separate plant.

15-3-2017 GANDIA RIO SERPIS, VALENCIA - EUROPEAN GOLDFINCH (MALE) (Carduelis carduelis)

Beautiful little finch with a sharp pink bil, cherry-red face, and brilliant black-and-yellow flashes in the wings. Western birds (Europe east to far western Central Asia) have a black-and-white cowl; eastern birds (rest of Central Asia) lack this cowl, and are grayer overall, with more white on the wing. Juvenile (seen in late summer and autumn) has a plain head but is told easily by bold wing pattern. Uses a wide array of wooded and open habitats, from forests and gardens to steppe grasslands and meadows; often feeds on seeding thistles. Forms flocks in autumn and winter, gathering at food sources. Can be inconspicuous, but often detected by pleasant bubbling and twittering calls and song.

23-3-2017 RANCHO NATURALISTA COSTA RICA - LESSON'S MOTMOT (Momotus lessonii)

The central crown is black and surrounded by a blue band. There is a black eyemask. The call is a low owl-like ooo-doot.

These birds often sit still, and in their dense forest habitat can be difficult to see, despite their size. They eat small prey such as insects and lizards, and will also regularly take fruit.

Like most of the Coraciiformes, motmots nest in tunnels in banks, laying about three or four white eggs.

15-3-2017 GANDIA RIO SERPIS, VALENCIA - SARDINIAN WARBLER (MALE) (Sylvia melanocephala)

The Sardinian Warbler (Sylvia melanocephala) is a small species of songbird common in the Mediterranean region. This species is common throughout a range of habitats including coastal scrub, forests, farmland and gardens. The song of the Sardinian Warbler is a series of scratchy, melodic chattered phrases and is a common sound throughout much of its range. They also make a range of harsher calls with repeated ‘tchra’ notes. This species often sings while perched on top of a bush or in a display flight. The audio in the video below was recorded in spring in Los Alcornocales Natural Park, Andalucia, Spain. The common name for this species in Spanish is Curruca cabecinegra.

31-3-2017 MIAMI, FLORIDA - BARRED OWL (Strix varia)

The Barred owl (Strix varia) is a North American large species of owl. These are large nocturnal birds probably best known for their unique vocalizations that carry well over 0.8 km (0.50 mi). They have typical nesting habits for a true owl and raise a relatively small brood often in a tree hollow or snag in forested areas.

Barred owls are brown to gray overall with dark striping on the underside contrasted immediately above that with similarly dark and tight barring about their throat and nape. Their head is fairly large and rounded with no ear tufts. The bill is pale straw-yellow (occasionally showing a mild greenish tint) while the cere is “horn”-colored. Their soulful eyes are blackish-brown in color. Like most birds of prey, females in this species are larger than males.

Barred owls are found throughout most of the eastern United States, as well as much of southern Canada and Mexico. They live in old deciduous, mixed forests and, occasionally, coniferous forests. Barred owls can also be found in deep moist forests, semi-open wooded areas, oak savanna or cabbage-palm areas, riparian areas or swampy ground, agricultural fields, wetlands, open terrain, and large parks with old trees.

11-3-2017 COLUMBIA - SCRUB TANAGER (Stilpnia vitriolina)

This Andean species is fairly common in open, dry habitats in Colombia and Ecuador. Look for a mostly blue-grey bird with brighter turquoise wings, a black mask and an orange cap. Sexes alike. Most similar to Burnished-buff Tanager but no range overlap. Usually seen in pairs or small flocks moving through woodland shrubs, secondary forest and gardens.

The scrub tanager (Stilpnia vitriolina ) is a species of bird in the family Thraupidae.

It is found in Colombia and Ecuador. Its natural habitats are subtropical or tropical moist montane forests, subtropical or tropical high-altitude shrubland, and heavily degraded former forest.

11-3-2017 MONTE CORONA, VALENCIA - RED LEGGED PARTRIDGE (Alectoris rufa)

The red-legged partridge, Alectoris rufa, is a plump gamebird belonging to the pheasant family, Phasianidae. It is colloquially known as the French partridge, setting it apart from the English or grey partridge. Exhibiting a light brown back, grey breast, and buff belly, this bird is easily recognized by its white face with a striking black gorget. The flanks are adorned with rufous streaks, and it stands on characteristically red legs. When startled, it may choose to run, but it can also take to the air with rounded wings for short distances.

Adults display a sandy-brown upper body, a pinkish-buff belly, and a pale grey breast. A black gorget with bold rufous and black flank bars, a cream throat, pink legs, and a red bill and eye ring are distinctive features. The eye is encircled by a bright red ring, adding to its striking appearance.

The red-legged partridge favors dry lowlands for breeding, such as farmland and open stony areas. It nests on the ground and can be found cohabiting with wild rabbits.

Originally from southwestern Europe, including France, Iberia, and northwest Italy, the red-legged partridge has been introduced and naturalized in parts of England and Wales. It forms flocks outside the breeding season and is a non-migratory terrestrial species.

This bird is known for its preference to run rather than fly when disturbed. However, it is capable of short flights if necessary. It is a sociable species, forming flocks when not breeding.

The red-legged partridge vocalizes with a distinctive three-syllable call, which can be phonetically described as "ka-chu-chu."

The species is known to breed in dry lowland areas, laying eggs in a ground nest. It has the remarkable ability to breed two clutches simultaneously.

The rock partridge (Alectoris graeca) is very similar in appearance and occupies southeastern Europe, replacing the red-legged partridge there.

Primarily seed-eating, the red-legged partridge's diet also includes insects, which are particularly important for the protein needs of the young.

The red-legged partridge is currently classified as Near Threatened by the IUCN, with concerns about its decline across its range due to habitat loss and overhunting.

11-3-2017 GANDIA, VALENCIA - SPECKLED WOOD BUTTERFLY (Pararge aegeria)

The speckled wood (Pararge aegeria) is a butterfly found in and on the borders of woodland areas throughout much of the Palearctic realm. The species is subdivided into multiple subspecies, including Pararge aegeria aegeria, Pararge aegeria tircis, Pararge aegeria oblita, and Pararge aegeria insula. The color of this butterfly varies between subspecies. The existence of these subspecies is due to variation in morphology down a gradient corresponding to a geographic cline. The background of the wings ranges from brown to orange, and the spots are either pale yellow, white, cream, or a tawny orange. The speckled wood feeds on a variety of grass species. The males of this species exhibit two types of mate locating behaviors: territorial defense and patrolling. The proportion of males exhibiting these two strategies changes based on ecological conditions. The monandrous female must choose which type of male can help her reproduce successfully. Her decision is heavily influenced by environmental conditions.

The speckled wood occupies a diversity of grassy, flowery habitats in forest, meadow steppe, woods, and glades. It can also be found in urban areas alongside hedges, in wooded urban parks, and occasionally in gardens. Within its range the speckled wood typically prefers damp areas. It is generally found in woodland areas throughout much of the Palearctic realm. P. a. tircis is found in northern and central Europe, Asia Minor, Syria, Russia, and central Asia, and the P. a. aegeria is found in southwestern Europe and North Africa. Two additional subspecies are found within the British Isles: the Scottish speckled wood (P. a. oblita) is restricted to Scotland and its surrounding isles, and the Isles of Scilly speckled wood (P. a. insula) is found only on the Isles of Scilly. P. a. tricis and P. a. aegeria gradually intergrade into each other.

11-3-2017 GANDIA, VALENCIA - EUROPEAN SERIN (MALE) (Serinus serinus)

The European serin, or simply the serin (Serinus serinus), is a diminutive member of the finch family, Fringillidae.

The serin's plumage is a tapestry of nature's palette, with upper parts dappled in dark-streaked greyish green and a conspicuous yellow rump. The underparts are a canvas of yellow breast and white belly, both adorned with heavy streaks.

When attempting to identify the European serin, look for the male's radiant yellow face and breast, which stand out against the greenish backdrop of its feathers. The male also boasts yellow wing bars and yellow tail sides, which can be quite helpful in distinguishing it from similar species. Both sexes share a buzzing trill of a song that resonates through their Mediterranean habitats.

The European serin is partial to open woodland and cultivated areas, often with a sprinkling of conifers. These environments provide the perfect backdrop for breeding and foraging.

This species has a breeding range that extends across southern and central Europe and into North Africa. Populations along the southern and Atlantic coasts tend to be resident, while those in the north are migratory, seeking warmer climates in southern Europe during the winter months.

Outside of the breeding season, the European serin is a sociable creature, forming flocks that may sometimes mingle with other finch species. It is an active and often conspicuous bird, its presence easily announced by its distinctive trill.

The serin's song is a distinctive buzzing trill, a sound that becomes part of the ambient music in regions where these birds are common.

The European serin weaves its nest within the shelter of a shrub or tree, where it lays a clutch of 3 to 5 eggs. The chosen breeding habitats are often areas of open woodland and cultivation, with a preference for some conifers.

The diet of the European serin is predominantly seeds, but it does not shy away from including insects during the breeding season, providing essential protein for its young.

The IUCN Red List categorizes the European serin as Least Concern, indicating that, for now, this species does not face any imminent threats to its survival.

10-3-2017 VILLALONGA RESERVOIR - CATTLE EGRET (Bubulcus ibis)

The Cattle egret (Bubulcus ibis) is a cosmopolitan species of heron named for its association with cattle. It is the only member of the monotypic genus Bubulcus, although some authorities regard its two subspecies as full species, the Western cattle egret and the Eastern cattle egret. Despite the similarities in plumage to the egrets of the genus Egretta, it is more closely related to the herons of Ardea.

The Cattle egret is a stocky bird. It has a relatively short, thick neck, a sturdy bill, and a hunched posture. The nonbreeding adult has mainly white plumage, a yellow bill, and greyish-yellow legs. During the breeding season, adults of the nominate western subspecies develop orange-buff plumes on the back, breast, and crown, and the bill, legs, and irises become bright red for a brief period prior to pairing. The sexes are similar, but the male is marginally larger and has slightly longer breeding plumes than the female; juvenile birds lack coloured plumes and have a black bill.

Cattle egrets are native to parts of Asia, Africa, and Europe but they have undergone a rapid expansion in their distribution and successfully colonized much of the rest of the world in the last century. Many populations of Cattle egrets are highly migratory, while others are dispersive, and distinguishing between the two can be difficult. In many areas, populations can be both sedentary and migratory. In the Northern Hemisphere, migration is from cooler climes to warmer areas, but Cattle egrets nesting in Australia migrate to cooler Tasmania and New Zealand in the winter and return in the spring. Migration in western Africa is in response to rainfall, and in South America, migrating birds travel south of their breeding range in the non-breeding season. Populations in southern India appear to show local migrations in response to the monsoons. Cattle egrets inhabit wetlands, dry grassy habitats, semi-arid steppes, floodplains, freshwater swamps, shallow marshes, and mangroves. They are often found in fields, croplands, and pastures with poor drainage. When nesting, Cattle egrets are found in woodlands near lakes or rivers, in swamps, or on small inland or coastal islands.

10-3-2017 PEGO MARJAL, ALICANTE - EURASIAN TREE SPARROW (MALE) (Passer montanus)

The Eurasian tree sparrow (Passer montanus) is asmall passerine bird that breeds over most of temperate Eurasia and Southeast Asia, where it is known as the Tree sparrow. It has been introduced elsewhere including the United States, where it is known as the Eurasian tree sparrow or German sparrow to differentiate it from the native unrelated American tree sparrow.

The adult's crown and nape are rich chestnut, and there is a kidney-shaped black ear patch on each pure white cheek; the chin, throat, and the area between the bill and throat are black. The upperparts are light brown, streaked with black, and the brown wings have two distinct narrow white bars. The legs are pale brown, and the bill is lead-blue in summer, becoming almost black in winter. This sparrow is distinctive even within its genus in that it has no plumage differences between the sexes; the juvenile also resembles the adult, although the colors tend to be duller. Its contrasting face pattern makes this species easily identifiable in all plumages; the smaller size and brown, not grey, crown are additional differences from the male house sparrow. Adult and juvenile Eurasian tree sparrows undergo a slow complete molt in the autumn and show an increase in body mass despite a reduction in stored fat. The change in mass is due to an increase in blood volume to support active feather growth and generally higher water content in the body.The adult's crown and nape are rich chestnut, and there is a kidney-shaped black ear patch on each pure white cheek; the chin, throat, and the area between the bill and throat are black.

10-3-2017 PEGO MARJAL, ALICANTE - EUROPEAN ROBIN (Erithacus rubecula)

The European robin (Erithacus rubecula), known simply as the robin or robin redbreast in Great Britain and Ireland, is a small insectivorous passerine bird, a member of the chat subfamily of the Old World flycatcher family. It is a plucky little bird, with a length of about 12.5–14.0 cm and a weight of 16–22 g. Both sexes are similarly adorned with an orange breast and face, lined with grey, brown upper-parts, and a whitish belly.

Adult robins can be identified by their orange breast and face, bordered by a bluish-grey on the sides of the neck and chest. The upperparts are brownish, or olive-tinged in British birds, and the belly is whitish. The bill and eyes are black. Juvenile robins are distinguishable by their spotted brown and white plumage, with patches of orange gradually appearing as they mature.

The European robin is a bird of diverse habitats, found in woodlands, gardens, and parks across its range. It is particularly associated with areas where the soil is dug or disturbed, allowing it easy access to its invertebrate prey.

This bird has a wide distribution across Europe, extending east to Western Siberia and south to North Africa. It is sedentary in most of its range except the far north, where it is migratory. 

10-3-2017 PEGO MARJAL, ALICANTE - BOOTED EAGLE (Hieraaetus pennatus)

The booted eagle, Hieraaetus pennatus, is a medium-sized bird of prey, with a stature comparable to the common buzzard. It exhibits sexual dimorphism, with females being larger, weighing approximately 840–1,025 grams, while males are lighter at 510–770 grams. The species measures around 40 cm in length and boasts a wingspan ranging from 110 to 132 cm. It is characterized by two distinct plumage morphs: a pale variant with light grey feathers and a darker head and flight feathers, and a darker morph with mid-brown plumage and dark grey flight feathers.

When identifying the booted eagle, look for the white markings on the wings, often referred to as "landing lights," which are visible when the bird is in flight. The pale morph is dominant, but the darker morph can be more prevalent in certain eastern populations. The call of the booted eagle is a distinctive shrill "kli-kli-kli."

The booted eagle favors wooded, often hilly landscapes with some open areas. It breeds in rocky, broken terrain but is adaptable during migration, utilizing a variety of habitats except dense forests.

This raptor has a wide distribution, breeding in southern Europe, North Africa, and across Asia, with a disjunct breeding population in southwestern Africa. Northern populations are migratory, wintering in Sub-Saharan Africa and South Asia, while the southern African populations are sedentary.

The booted eagle is typically observed flying at low altitudes, making it quite conspicuous. It is often seen in pairs or as solitary individuals. The species is known for its sophisticated courtship rituals involving elaborate flight displays.

The booted eagle's vocalization is a piercing "kli-kli-kli," which can be heard during its flight.

Monogamous by nature, the booted eagle lays 1-2 eggs in a nest constructed from sticks and lined with green leaves, either in a tree or on a crag. The female incubates the eggs for about 45 days, while the male provides food. After hatching, the female continues to guard the nest and the young, with the male supplying all the nourishment until the chick fledges after 70-75 days.

The dark morph of the booted eagle may be confused with other local medium-sized birds of prey due to its coloration and size.

The booted eagle hunts small mammals, reptiles, and birds, often stooping from flight with wings folded and feet extended to capture its prey. In Southern Africa, birds are the most common prey, although frogs are also suggested to be an important dietary component elsewhere.

The booted eagle is currently listed as Least Concern on the IUCN Red List. However, there is a notable lack of research on this species, particularly the Southern African populations, which were only discovered in the 1980s. Changes in climate and human land use may influence migration patterns, underscoring the need for further study to understand the ecology and conservation status of this species.
