1-1-2020 CREU DE LONGA, VALENCIA - EURASIAN KESTREL (Falco tinnunculus)

The common kestrel, Falco tinnunculus, is a bird of prey from the kestrel group within the falcon family Falconidae. It is also known as the European kestrel, Eurasian kestrel, or Old World kestrel. In the United Kingdom, it is often simply referred to as the "kestrel." This raptor is small compared to other birds of prey but larger than most songbirds, with long wings and a distinctive long tail.

Males and females exhibit sexual dimorphism in their plumage. The male has a blue-grey cap and tail with a black tip bordered by a narrow white rim. Its back is chestnut with black spots, and the underside is buff with black streaks. The female is larger and lacks the blue-grey coloring, having a brown back with black bars and a similar underside to the male. Both sexes have a prominent black malar stripe, bright yellow cere, feet, and eye-ring, with dark toenails, bill, and iris.

The common kestrel favors open habitats such as fields, heaths, shrubland, and marshland. It does not require woodland but needs alternative perching and nesting sites like rocks or buildings. It thrives in treeless steppes and can adapt to human settlements and various landscapes, from wetlands to arid savannas.

This species has a vast range, being widespread in Europe, Asia, and Africa, and occasionally reaching the east coast of North America. It has colonized some oceanic islands, though vagrant individuals are generally rare.

The common kestrel is diurnal and can be sedentary or migratory, depending on the region. It is known for its characteristic hunting behavior, hovering 10-20 meters above the ground before diving steeply onto prey. It is also capable of seeing ultraviolet light, which aids in detecting the urine trails of small mammals.

Breeding occurs in spring or the start of the dry season, with the kestrel preferring cavity nests in cliffs, trees, or buildings. Clutches typically consist of 3-7 eggs, which are incubated by both parents. The young fledge after 4-5 weeks and stay with the family for a short period thereafter.

The lesser kestrel and American kestrel are similar but not closely related. The lesser kestrel lacks black on the upperside except for wing and tail tips, while the American kestrel has much grey in the wings of males.

's diet consists almost exclusively of mouse-sized mammals, such as voles, shrews, and true mice. It may also consume small birds, particularly during the summer when fledglings are abundant. Invertebrates and arthropods can be significant food sources seasonally.

The IUCN lists the common kestrel as Least Concern. Its population has fluctuated but remains generally stable, with an estimated 1-2 million pairs globally. Some subspecies, such as those in the Canary Islands, are rarer and number less than 1000 adult birds.

1-1-2020 CREU DE LONGA, VALENCIA - EUROPEAN STARLING (Sturnus vulgaris)

The Common Starling, Sturnus vulgaris, is a medium-sized passerine bird characterized by its glossy black plumage with a metallic sheen. Throughout the year, the plumage is speckled with white, though less so during the breeding season. Adults measure approximately 20 cm in length, with pink legs and a seasonally changing bill color—black in winter and yellow in summer. Juveniles display browner plumage compared to adults.

To identify the Common Starling, look for its iridescent black feathers, which may appear purple or green when reflecting light. The bird's bill is black in the winter and transitions to yellow in the summer, aiding in identification. The starling's flight is strong and direct, with pointed wings that are distinctive in the air. On the ground, its waddling gait is notable.

1-1-2020 CREU DE LONGA, VALENCIA - ZITTING CISTICOLA (Cisticola juncidis)

The Zitting Cisticola, or Streaked Fantail Warbler, is a diminutive bird, measuring a mere 10 to 12 centimeters in length. Its upper parts are adorned with a brown plumage, intricately streaked with black, while its underparts remain a modest whitish hue. The tail is a noteworthy feature, broad and tipped with white, and is frequently flicked—a behavior that has inspired one of the bird's colloquial names.

To identify the Zitting Cisticola, look for its rufous rump and the absence of gold on the collar. The tail, brownish with white tips, is another distinguishing characteristic. Males, during the breeding season, exhibit less crown streaking and more pronounced back markings than females, though differences between sexes are generally subtle.

The Zitting Cisticola favors grasslands as its primary habitat, often found in proximity to bodies of water.

23-3-2017 SAN GERARDO DE DOTA COSTA RICA - RED CROWNED WOODPECKER (Melanerpes rubricapillus)

The red-crowned woodpecker, Melanerpes rubricapillus, is a vibrant member of the woodpecker family, Picidae. This species exhibits a striking plumage, with both sexes adorned in a similar fashion, save for subtle differences in their head patterns. Adults typically measure between 16 to 18.5 cm in length and weigh between 40 to 65 grams.

To identify the red-crowned woodpecker, look for the adult male's bright red crown and orange-red nape, contrasted with a pale yellow to whitish forehead. The female, while sharing the pale forehead, features a more subdued crown of pale gray-buff to whitish tones, with a reddish to orange-red nape. Both sexes have grayish-buff cheeks, chin, and throat, with a barred black and white mantle and back. Their underparts are generally buffish-gray with a reddish to orange-red central belly patch.

This species thrives in a variety of environments, from the interiors of mature deciduous forests to secondary forests, coastal scrublands, mangroves, and even human-altered landscapes such as plantations and gardens.

The red-crowned woodpecker is found across a broad range, from southwestern Costa Rica through Panama, into northern and central Colombia, the northern half of Venezuela, Guyana, Suriname, and Tobago.

As year-round residents, these woodpeckers are often observed foraging alone or in pairs, utilizing a combination of probing, gleaning, and hammering to extract their insect prey, as well as reaching for fruits which they skillfully pierce or peck open.

The red-crowned woodpecker is known for its distinctive calls, which include a wavering "churr, churr, krr-r-r-r," a display "wícka, wícka," and various chattering sounds. Both sexes engage in drumming, particularly during the breeding season, and also produce softer taps near their nest holes.

Breeding seasons vary by location, with nests typically constructed in large tree trunks, branches, or cacti. Clutch sizes are usually three to four eggs, but often only two young successfully fledge. Both parents share in the incubation over a 10-day period and continue to care for the nestlings and fledglings post-hatching.

While there are no specific similar species mentioned, it is important to note the differences among the subspecies, such as the slightly smaller M. r. subfusculus with darker underparts, or M. r. paraguanae with a paler yellow forehead and wider white bars on its upperside.

The diet of the red-crowned woodpecker is diverse, including a significant amount of fruits and berries, insects, spiders, and nectar from flowers. They are known to frequent feeders and can be considered a nuisance in plantations and gardens due to their fruit-eating habits.

The IUCN has classified the red-crowned woodpecker as Least Concern, with a stable population estimated to be over half a million mature individuals. It is common throughout most of its range and even abundant in some areas, potentially benefiting from forest clearance that creates more open woodland habitats.

24-3-2017 RANCHO NATURALISTA, COSTA RICA - BAY HEADED TANAGER (Tangara gyrola)

The bay-headed tanager (Tangara gyrola) is a medium-sized passerine bird. This tanager is a resident breeder in Costa Rica, Panama, South America south to Ecuador, Bolivia and north-western Brazil, and on Trinidad.

It occurs in forests, particularly in wetter areas. The bulky cup nest is built in a tree and the normal clutch is two brown-blotched white eggs. The female incubates the eggs for 13–14 days to hatching, with another 15–16 days before the chicks fledge.

These are social birds which eat mainly fruit, usually swallowed whole. Insects are also taken, mainly from the underside of branches.

This tanager favors forested environments, showing a preference for the more humid regions. It is adept at making its home in these lush habitats, where it constructs a bulky cup nest within the trees.

The Bay-headed Tanager is a resident breeder with a wide range extending from Costa Rica and Panama through South America to Ecuador, Bolivia, and northwestern Brazil. It is also found on the island of Trinidad.

Bay-headed Tanagers are sociable creatures, often seen in groups. They primarily feed on fruit, which they typically consume whole. Insects also form part of their diet, with a particular penchant for those found on the underside of branches.

The song of the Bay-headed Tanager is a melodious sequence of slow 'seee, seee, seee, tsou, tsooy' notes, which can be heard resonating through their forested habitats.

The species constructs a robust cup-shaped nest in trees to lay their clutch, typically consisting of two white eggs adorned with brown blotches. The female takes on the responsibility of incubating the eggs for a period of 13 to 14 days until they hatch. The fledging period for the chicks lasts an additional 15 to 16 days.

31-12-2019 MONTE CORONA, VALENCIA - SHEEPS-BIT (Jasione montana)

Jasione montana is a low-growing plant in the family Campanulaceae found in rocky places and upland regions of Europe and western Asia. Common names include sheep's-bit, blue bonnets, blue buttons, blue daisy and iron flower. Due to the similarity of the common name of "sheep's-bit" with that of devil's-bit scabious (Succisa pratensis), it is sometimes called "sheep's-bit scabious" or "sheep scabious", but it is not closely related to the scabious genus (Scabiosa).

This plant is found in the temperate zone of Europe and northwestern Africa. It is a plant growing on heaths and moors in rocky or sandy districts, coastal cliffs, quarries and natural escarpments where the soil is thin. It prefers acid soils and is absent from limestone regions. It is often found on coastal cliffs in association with thrift and kidney vetch and blooms from May to September.

31-12-2019 MONTE CORONA, VALENCIA - PEA BLUE BUTTERFLY (Lampides boeticus)

The pea blue butterfly, also known as the Long-tailed Pea Blue, is a widely distributed species with a wingspan of about 2.5–3.0 cm. It is known for the male's purplish-blue upper wings and the female's brown wings with a blueish tinge. A key feature is the "false head" created by two black spots and fine, tail-like filaments on the hindwings, which helps confuse predators. 

Appearance and identification

Males: Have a vivid purplish-blue upper side with dark brown margins.

Females: Have a more muted appearance, with brown upper wings that have a blue-purple wash, especially on the forewings.

Underside: Both sexes share a light brown underside with white, linear markings and a pronounced white band near the outer edge.

"False head": The hindwings have two small black spots on the outer margin, with a sky-blue or metallic green rim, and a fine, tail-like appendage that mimics an antenna.

Size: The wingspan is typically between 2.5 and 3.0 cm. 

Habitat and distribution

Widespread: Found across Europe, Asia, and Africa, and in parts of Australia and New Zealand.

Adaptable: Lives in a variety of habitats, including suburban gardens.

Migratory: This species is a strong and active migrant. 

Behavior and life cycle

Flight: They have a fast and jerky flight style and often stay close to the ground.

Basking: They often bask with their wings partially open, both in the morning and around midday.

Feeding: Adults feed on nectar and may also be attracted to damp soil to absorb minerals.

Pest status: Can be considered a minor pest in gardens, as the larvae feed on leguminous plants like peas and beans.

Ant association: The larvae are sometimes attended by ants, which protect them from predators. 

30-12-2019 RIO SERPIS VILLALONGA, VALENCIA - GREY HERON (Ardea cinerea)

The Grey Heron (Ardea cinerea) is a statuesque wading bird belonging to the family Ardeidae. It is a familiar sight in both rural and urban settings, often seen standing stoically along the water's edge. An adult Grey Heron is a large bird, reaching up to 100 cm in height, with a wingspan between 155 to 195 cm. It weighs between 1 to 2 kg. The plumage is predominantly ashy-grey above, with a greyish-white underbelly and some black on the flanks. A striking feature is the white head and neck adorned with a broad black stripe that extends from the eye to the black crest. The beak is pinkish-yellow, long, and sharply pointed, while the legs are a brown hue.

When identifying the Grey Heron, look for the white head with the black supercilium and crest, the long grey neck, and the ashy-grey wings and back. The underparts are lighter, and the legs are long and brown. Juveniles can be distinguished by their duller grey neck and smaller crest. The beak is a useful indicator of age, being brighter in breeding adults.

Grey Herons are highly adaptable and can be found in a variety of watery habitats including lakes, rivers, ponds, marshes, and coastal environments. They require shallow waters for foraging or areas with shelving margins where they can wade.

Native to temperate Europe and Asia, as well as parts of Africa, the Grey Heron has a broad range. Northern populations may migrate southwards in autumn, while others remain resident year-round. Vagrant sightings have occurred in the Caribbean, Bermuda, and parts of North America.

The Grey Heron exhibits a slow, deliberate flight with its neck retracted in an S-shape. It is known for its solitary foraging habits, often standing motionless or stalking prey through shallow waters. It is also a communal rooster, often found in trees or cliffs at night.

The primary call of the Grey Heron is a loud croaking "fraaank." At breeding colonies, a variety of guttural and raucous noises can be heard, including greeting calls between mates and alarm calls when predators are nearby.

Breeding takes place in colonies, or heronries, typically in high trees near water. Nests are reused and added to each year. The breeding season sees a clutch of three to five bluish-green eggs laid, which both parents incubate. Chicks fledge at 7-8 weeks old.

Grey Herons are apex predators within their ecosystem, feeding on a variety of aquatic creatures such as fish, amphibians, crustaceans, and insects. They have also been known to consume small mammals and juvenile birds.

The Grey Heron is classified as Least Concern by the IUCN, indicating a stable and widespread population.

30-12-2019 RIO SERPIS VILLALONGA, VALENCIA - MALLARD (MALE) (Anas platyrhynchos)

Mallards are adaptable, medium-sized dabbling ducks found in wetlands across the Northern Hemisphere. Males have a distinctive iridescent green head and yellow bill, while females are mottled brown with an orange bill. Both sexes have a blue-and-white-bordered wing patch and share a diet of seeds, plants, and small animals, with ducklings being mostly insect-eaters. 

Diet: Omnivorous, eating seeds, acorns, berries, aquatic plants, insects, and shellfish.

Foraging: Dabble for food in shallow water by tipping their bodies forward, or dive for food if necessary.

Habitat: Found in various wetlands, including marshes, ponds, and rivers, and are also common in urban areas like parks. 

29-12-2019 MONTE CORONA, VALENCIA - WAVE MOTH (idaea cervantaria)

1.4 to 2.2 cm wingspan. Straw-coloured, with yellowish wings with scattered dark, brown or greyish scales. On each wing it has a wavy line with small pointed spots, pointing backwards. Sometimes these details are barely noticeable. Between these lines and the rear edge, it has dark spots that may have a  light wavy stripe. It has a spot on each wing but those on the front wings may go unnoticed.

There are other similar species that are impossible to distinguish externally, so for a correct and safe identification, genital analysis must be used. Several of them have been found in the province of Malaga, although I. cervantaria is currently the most common and the only one that has been observed in urban environments.

The caterpillars feed on dry leaves of herbaceous plants and in captivity on petals of different Asteraceae and sea alder (Lobularia maritima), the latter common in our province, especially in sunny areas of the limestone mountains, and occasionally used in gardening for the showiness of its inflorescences.

29-12-2019 MARJAL DE GANDIA, VALENCIA - COMMON CHIFFCHAFF (Phylloscopus collybita)

The Common Chiffchaff, Phylloscopus collybita, is a diminutive and sprightly leaf warbler known for its distinctive, onomatopoeic song. This small, migratory passerine is characterized by its greenish-brown upperparts and off-white underparts, with a weight ranging from 6 to 8 grams and a length of 10-12 centimeters.

In the field, look for the Common Chiffchaff's short whitish supercilium, fine dark bill, and dark legs. Its primary projection is short, and the plumage may appear duller and browner as it wears. Juveniles are browner above with yellow-white underparts, but they soon acquire brighter plumage after their first moult.

The Common Chiffchaff breeds in open woodlands with a mix of taller trees and ground cover across northern and temperate Europe, Asia, and parts of north Africa. It prefers woodland with trees at least 5 meters high and an undergrowth of grasses and nettles.

This species has a vast breeding range, extending from Europe to eastern Siberia and northward to about 70 N. It winters in southern and western Europe, southern Asia, and north Africa. The Common Chiffchaff is one of the earliest spring migrants to return to its breeding grounds and one of the last to depart in autumn.

29-12-2019 MARJAL DE GANDIA, VALENCIA - EUROPEAN ROBIN (Erithacus rubecula)

European robins occur in Eurasia east to Western Siberia, south to Algeria, and on the Atlantic islands as far west as the Central Group of the Azores and Madeira. Irish and British robins are largely resident but a small minority, usually female, migrate to southern Europe during winter, a few as far as Spain. Scandinavian and Russian robins migrate to Britain and western Europe to escape the harsher winters. European robins prefer spruce woods in northern Europe, contrasting with their preference for parks and gardens in Ireland and Great Britain. These may also be found in grasslands, shrubby vegetation, hedgerows with some tall trees, orchards, and farmlands.

European robins are active during the day, however, they may also hunt insects on moonlit nights or near artificial light at night. These are generally solitary and territorial birds, and males are noted for their highly aggressive territorial behavior. They will fiercely attack other males and competitors that stray into their territories and may even attack other small birds without apparent provocation. 

European robins communicate using a variety of calls, including a ticking note that usually indicates anxiety or mild alarm. During the breeding season, robins produce a fluting, warbling song. Both the male and female sing during the winter, when they hold separate territories; the song then sounds more plaintive than the summer version. 

The female typically moves a short distance from the summer nesting territory to a nearby area that is more suitable for winter feeding. The male keeps the same territory throughout the year. During the breeding season, males usually initiate their morning song an hour before civil sunrise and usually terminate their daily singing around thirty minutes after sunset. They may also sing at night, especially in urban areas that are artificially lit during the night.

29-12-2019 MARJAL DE GANDIA, VALENCIA - MEADOW PIPIT (Anthus pratensis)

The meadow pipit (Anthus pratensis) is a small passerine bird, which breeds in much of the Palearctic, from southeastern Greenland and Iceland east to just east of the Ural Mountains in Russia, and south to central France and Romania; an isolated population also occurs in the Caucasus Mountains. It is migratory over most of its range, wintering in southern Europe, North Africa, and south-western Asia, but is resident year-round in western Europe, though even here many birds move to the coast or lowlands in winter.

The nest is on the ground hidden in dense vegetation, with two to seven (most often three to five) eggs; the eggs hatch after 11–15 days, with the chicks fledging 10–14 days after hatching. Two broods are commonly raised each year. This species is one of the most important nest hosts of the cuckoo, and it is also an important prey species for merlins and hen harriers.

Its food is primarily insects and other invertebrates, mostly small items less than 5 mm (3⁄16 in) long. It also eats the seeds of grasses, sedges, rushes, and heather, and crowberry berries, mainly in winter.

29-12-2019 MARJAL DE GANDIA, VALENCIA - 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.

The robin is diurnal and is known for its boldness in human presence, often seen investigating gardeners at work. It is territorial, with males known to fiercely defend their territory. The robin's diet is primarily composed of insects and worms, but it will also consume berries and fruit, especially in autumn and winter.

The robin's song is a delightful fluting warble, more plaintive during the winter months. Both sexes sing, with the male's song typically starting before dawn and ending after dusk. Urban robins may sing at night, possibly to avoid noise pollution during the day.

Robins are versatile in their choice of nesting sites, often opting for unusual locations such as nooks in machinery or even discarded clothing. They typically lay two or three clutches of eggs per season, with the eggs being cream, buff, or white and speckled with reddish-brown.

Robins primarily feed on insects, spiders, and worms. During colder months, their diet is supplemented with berries and fruit. They are also known to visit bird tables for seed mixtures and suet.

29-12-2019 MARJAL DE GANDIA, VALENCIA - MALLARD HYBRID (MALLARD X MUSCOVY DUCK) (Anas platyrhynchos × Cairina moschatas)

Anas is a genus of dabbling ducks. It includes the pintails, most teals, and the mallard and its close relatives. It formerly included additional species but following the publication of a molecular phylogenetic study in 2009 the genus was split into four separate genera. The genus now contains 31 living species. The name Anas is the Latin for "duck".

The genus Anas was introduced by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his Systema Naturae. Anas is the Latin word for a duck. 

The genus formerly included additional species.

In 2009 a large molecular phylogenetic study was published that compared mitochondrial DNA sequences from ducks, geese and swans in the family Anatidae. The results confirmed some of the conclusions of earlier smaller studies and indicated that the genus as then defined was non-monophyletic. Based on the results of this study, Anas was split into four proposed monophyletic genera with five species including the wigeons transferred to the resurrected genus Mareca, ten species including the shovelers and some teals transferred to the resurrected genus Spatula and the Baikal teal placed in the monotypic genus Sibirionetta.

29-12-2019 VILLALONGA RESERVOIR, VALENCIA - EURASIAN GREAT CORMORANT (Phalacrocorax carbo)

The great cormorant (Phalacrocorax carbo), known as the black shag or kawau in New Zealand, formerly also known as the great black cormorant across the Northern Hemisphere, the black cormorant in Australia, and the large cormorant in India, is a widespread member of the cormorant family of seabirds. The genus name is Latinised Ancient Greek, from φαλακρός (phalakros, "bald") and κόραξ (korax, "raven"), and carbo is Latin for "charcoal".

It breeds in much of the Old World, Australia, and the Atlantic coast of North America.

The great cormorant is a large black bird, but there is a wide variation in size in the species' wide range. Weight is reported to vary from 1.5 kg (3 lb 5 oz) to 5.3 kg (11 lb 11 oz). Males are typically larger and heavier than females, with the nominate race (P. c. carbo) averaging about 10% larger in linear measurements than the smallest race in Europe (P. c. sinensis). The lightest average weights cited are in Germany (P. c. sinensis), where 36 males averaged 2.28 kg (5 lb 1⁄2 oz) and 17 females averaged 1.94 kg (4 lb 4+1⁄2 oz). The highest come from Prince Edward Island in Canada (P. c. carbo), where 11 males averaged 3.68 kg (8 lb 2 oz) and 11 females averaged 2.94 kg (6 lb 7+1⁄2 oz). Length can vary from 70 to 102 cm (27+1⁄2 to 40 in) and wingspan from 121 to 160 cm (47+1⁄2 to 63 in). They are tied as the second largest extant species of cormorant after the flightless cormorant, with the Japanese cormorant averaging at a similar size. 

28-12-2019 MONTE CORONA, VALENCIA - 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.

28-12-2019 MONTE CORONA, 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.

In northern Europe, it is one of the last butterflies to be seen before winter sets in, often feeding on the flowers of ivy on sunny days. The red admiral is also known to hibernate, re-emerging individuals showing prominently darker colors than the first brood. The butterfly also flies on sunny winter days, especially in southern Europe.

Male red admirals are territorial and perch during the afternoon until sunset. Larger territories are optimal and subject to intrusion by other males more frequently than smaller territories. Territories tend to be oval, 8–24 feet (2.4–7.3 m) long and 13–42 feet (4.0–12.8 m) wide. Males patrol their territory by flying around the perimeter between 7 and 30 times per hour. On average, territory holders interact with intruders 10 to 15 times per hour.

When another male encroaches on a red admiral's territory, the resident chases away the intruder, often in a vertical, helical path to disorient or tire out the intruder while minimizing the horizontal distance it travels from its perch. The red admiral immediately returns to its territory after chasing off encroaching males. Time spent patrolling increases as number of the intruder interactions increases.

28-12-2019 MONTE CORONA, VALENCIA - LANG'S SHORT TAILED BLUE BUTTERFLY (Leptotes pirithous)

Leptotes pirithous, commonly known as Lang's short-tailed blue or common zebra blue, is a butterfly of the family Lycaenidae.

Leptotes pirithous is a small butterfly with a wingspan of 21–29 mm (0.83–1.14 in) in males and 24–30 mm (0.94–1.18 in) in females. The uppersides of the wings are purple bluish in males, bluish brown in female. The undersides are dark beige striped with white lines. The hindwings show marginal orange and black spots and two small tails. For the design of the undersides of the wings they can be confused with Lampides boeticus and Cacyreus marshalli.

These butterflies fly from February to November depending on the location. They are regular migrants.

The larvae feed on the flowers and fruits of Fabaceae, Rosaceae and Plumbaginaceae species, including Plumbago capensis, Indigofera, Rynchosia, Vigna, Burkea, Mundulea, Melilotus, Crataegus, Quercus suber, Medicago sativa, Trifolium alexandrinum, Arachis hypogaea, Lythrum, Calluna, Genista, Dorycnium, Lythrum salicaria, Calluna vulgaris, Onobrychis viciifolia, Ulex and Melilotus alba. A life cycle takes about four to eight weeks, depending on the temperature.

28-12-2019 MONTE CORONA, VALENCIA - WESTERN HONEY BEE ( Apis mellifera)

The western honey bee or European honey bee (Apis mellifera) is the most common of the 7–12 species of honey bees worldwide. The genus name Apis is Latin for 'bee', and mellifera is the Latin for 'honey-bearing' or 'honey-carrying', referring to the species' production of honey.

Like all honey bee species, the western honey bee is eusocial, creating colonies with a single fertile female (or "queen"), many normally non-reproductive females or "workers", and a small proportion of fertile males or "drones". Individual colonies can house tens of thousands of bees. Colony activities are organized by complex communication between individuals, through both pheromones and the dance language.

The western honey bee was one of the first domesticated insects, and it is the primary species maintained by beekeepers to this day for both its honey production and pollination activities. With human assistance, the western honey bee now occupies every continent except Antarctica. Western honey bees are threatened by pests and diseases, especially the Varroa mite and colony collapse disorder. There are indications that the species is rare, if not extinct in the wild in Europe and as of 2014, the western honey bee was assessed as "Data Deficient" on the IUCN Red List. Numerous studies indicate that the species has undergone significant declines in Europe; however, it is not clear if they refer to population reduction of wild or managed colonies. Further research is required to enable differentiation between wild and non-wild colonies in order to determine the conservation status of the species in the wild, meaning self sustaining, without treatments or management.

27-12-2019 MONTE CORONA, VALENCIA - PUG MOTH (Genus Eupithecia)

Eupitheciini is a tribe of geometer moths under subfamily Larentiinae, often referred to as pugs. The tribe was described by Tutt in 1896.

The tribe consists of about 47 genera, 15 of which are monotypic.

Eupithecia is a large moth genus, also called 'pugs' due to short underwings. Adults often hold forewings at right angles, and the name means 'beautiful ape'.

Generic epithet Eupithecia is Greek meaning "beautiful ape." 

Commonly referred to as pugs because of the short underwings. 

By far the largest moth genus with over 1400 species worldwide. About 160 Eupithecia species are found in America north of Mexico. 62 species in Canada (CBIF). Several species are Holarctic.

 

Many Eupithecia species require dissection for identification and there are many undescribed species.  Adults at rest often hold their long forewings (with hindwings hidden beneath) at right-angles to the body, giving a distinctive "soaring hawk" appearance.

6-6-2019 KHWAI CAMP, BOTSWANA - WATER THICK NEE (Barhinus Vermiculatus)

The water thick-knee is a nocturnal bird found in sub-Saharan Africa that lives near freshwater. It forages for insects, crustaceans, and small vertebrates up to 1 km from water, and its diet can include a wide range of invertebrates and small vertebrates. It nests in a simple scrape on the ground and forms a unique symbiotic relationship with Nile crocodiles, where the birds act as sentries for the crocodiles' nests. 

Habitat and diet

Habitat: Found near rivers, lakes, estuaries, and beaches in sub-Saharan Africa.

Nocturnal behavior: Active at dawn, dusk, and night, though they can be seen during the day.

Foraging: Forages on the ground, sometimes up to a kilometer away from water.

Diet: Primarily feeds on insects, crustaceans (like crabs), and mollusks (like snails), but also eats frogs, tadpoles, and other small vertebrates. 

Breeding and nesting

Nesting: Builds a simple scrape in the ground, often near rocks or other structures for camouflage.

Eggs: Lays 1-3 sandy-yellow eggs, which both parents incubate for 22-25 days.

Parental care: Both parents are responsible for brooding the eggs and feeding the young, which fledge at around two months. 

Symbiotic relationship with Nile crocodiles

Mutualism: Often nests adjacent to or even on top of Nile crocodile nests.

"Sentry" duty: The loud and energetic thick-knees act as sentries, harassing and pecking at potential nest raiders.

Crocodile protection: If the thick-knees cannot drive off the intruder, their calls can alert the mother crocodile, which then protects its nest. 

Physical characteristics

Appearance: A terrestrial wading bird with large yellow eyes, a stout bill, and thick ankles.

Camouflage: Has cryptically colored plumage that blends in with sandy and rocky environments.

Size: Grows to about 38-41 cm in length and weighs around 440g. 

26-12-2019 POTRIES, VALENCIA - COMMON CHIFFCHAFF (Phylloscopus collybita)

The Common Chiffchaff, Phylloscopus collybita, is a diminutive and sprightly leaf warbler known for its distinctive, onomatopoeic song. This small, migratory passerine is characterized by its greenish-brown upperparts and off-white underparts, with a weight ranging from 6 to 8 grams and a length of 10-12 centimeters.

In the field, look for the Common Chiffchaff's short whitish supercilium, fine dark bill, and dark legs. Its primary projection is short, and the plumage may appear duller and browner as it wears. Juveniles are browner above with yellow-white underparts, but they soon acquire brighter plumage after their first moult.

The Common Chiffchaff breeds in open woodlands with a mix of taller trees and ground cover across northern and temperate Europe, Asia, and parts of north Africa. It prefers woodland with trees at least 5 meters high and an undergrowth of grasses and nettles.

This species has a vast breeding range, extending from Europe to eastern Siberia and northward to about 70 N. It winters in southern and western Europe, southern Asia, and north Africa. The Common Chiffchaff is one of the earliest spring migrants to return to its breeding grounds and one of the last to depart in autumn.

26-12-2019 POTRIES, VALENCIA - 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.
