8-5-2017 ARCOS DE FRONTERA, ANDALUSIA - SPOTTED OWL (Strix occidentalis)

The Spotted Owl, Strix occidentalis, is a medium-sized owl with a heart-shaped face and no ear tufts. It has a rounded head and a short, square tail. The plumage is mottled with dark brown and white spots, giving it excellent camouflage against the bark of trees. This owl is a true denizen of the forest, relying on the complex structure of old-growth habitats.

Adult Spotted Owls typically measure around 43 cm in length, with a wingspan of 114 cm, and weigh approximately 600 grams. Their eggs are white and smooth, with a slightly grainy texture, measuring just over 50 mm in length. To distinguish them from the similar Barred Owl, look for the Spotted Owl's characteristic cross-shaped markings on the underparts, as opposed to the Barred Owl's alternating bars and streaks.

The Spotted Owl inhabits a variety of forest types, showing a preference for closed-canopy, uneven-aged, late-successional, and old-growth forests. The Mexican subspecies also utilizes chaparral and pinyon woodlands, including steep-walled canyons with sparse canopy cover.

Three subspecies of the Spotted Owl are distributed from British Columbia to Mexico. The Northern Spotted Owl ranges from southwestern British Columbia through parts of California, while the California Spotted Owl's range extends further south. The Mexican Spotted Owl is found in disjunct populations across the Southwestern US and into western Mexico.

Spotted Owls are nocturnal and exhibit a sit-and-wait hunting strategy, often swooping down on prey from a perch. They are monogamous and exhibit high site fidelity, with some pairs using the same nesting sites repeatedly. These owls do not breed every year, and juveniles typically disperse in late summer to fall.

The Spotted Owl's vocalizations include a series of hoots, often described as haunting and ethereal, which can carry through the dense forest they call home.

Breeding season spans from early spring to late summer or fall. Spotted Owls do not construct their own nests but use tree cavities or abandoned nests of other birds. Clutch size is usually two eggs, but can occasionally be as many as four.

The Barred Owl (Strix varia) is the most similar species, being larger and grayer with different breast patterning. Hybridization with Barred Owls has resulted in "sparred owls," which are interspecific hybrids.

The Spotted Owl's diet primarily consists of small mammals and birds. Prey items include flying squirrels, woodrats, deer mice, pocket gophers, voles, hares, rabbits, and various species of squirrels. They also consume bats, birds, amphibians, reptiles, and insects to a lesser extent.

The Spotted Owl is classified as Near Threatened, with a decreasing population trend. Habitat loss and competition with the Barred Owl are significant threats. The Northern and Mexican subspecies are listed as threatened under the Endangered Species Act, with the California Spotted Owl proposed for listing. Conservation efforts include habitat protection and management, as well as experimental removal of competing Barred Owls.

8-5-2017 ARCOS DE FRONTERA, ANDALUSIA - RED TAILED HAWK (Buteo jamaicensis)

The Red-tailed Hawk (Buteo jamaicensis) is a robust bird of prey, one of the most familiar hawks in North America. This species exhibits a broad range of plumage variations, with 14 recognized subspecies differing in color and range. The Red-tailed Hawk is a large raptor, weighing between 690 to 1,600 grams (1.5 to 3.5 pounds), with a length of 45–65 centimeters (18–26 inches) and a wingspan of 110–141 centimeters (3 feet 7 inches – 4 feet 8 inches). Females are typically about 25% heavier than males. The species is known for its brick-red tail, which gives it its common name.

Adult Red-tailed Hawks have a rich brown upper body and pale underparts, with a streaked belly and a dark bar between the shoulder and wrist. The tail is usually a rich red color above and pale below, with a black subterminal band. Immature birds have a brown tail with dark bars and may lack the red coloration. The bird's beak is short and dark, and the legs and feet are yellow. In flight, the broad, rounded wings and short, wide tail are characteristic.

Red-tailed Hawks are highly adaptable and can be found in a variety of habitats, including deserts, grasslands, forests, agricultural fields, and urban areas. They prefer open areas with high perching sites from which they can survey their territory.

This species has a vast range, breeding from Alaska and northern Canada down through the United States to Panama and the West Indies. It is absent from the high Arctic and the most densely forested parts of the Amazon.

25-6-2014 PEGO MARSHES, ALICANTE - EUROPEAN MOORHEN (JUVENILE) (Gallinula chloropus)

2-6-2017 MONTE CORONA, VALENCIA - SARDINIAN WARBLER (MALE) (Sylvia melanocephala)

The Sardinian warbler, Curruca melanocephala, presents itself as a charming and distinctive bird of the Mediterranean. The males are adorned with a sleek grey back and pristine whitish underparts, crowned with a striking black head, a pure white throat, and captivating red eyes. The females, on the other hand, exhibit a more subdued palette, with brown upperparts and buff underparts, complemented by a subtle grey head.

When attempting to identify the Sardinian warbler, look for the male's black head and red eyes, which contrast with the white throat and grey back. Females can be recognized by their brown and buff coloration with a greyish head. The variability in plumage, including the presence or absence of a reddish hue, can be a helpful clue in distinguishing between subspecies.

This typical warbler favors open landscapes and cultivated areas, where it can find bushes suitable for nesting. Its preference for such environments makes it a familiar sight in the Mediterranean countryside.

The Sardinian warbler is a resident of the southernmost regions of Europe, extending its range into Asia in Turkey and the eastern Mediterranean. While not extensively migratory, some individuals do venture to North Africa for the winter, and the species has been known to appear as a vagrant as far as Great Britain.

This species is known for its affinity for open and cultivated areas with ample shrubbery for nesting. The Sardinian warbler constructs its nest in low shrubs or brambles, where it lays a clutch of 3-6 eggs. Its diet is primarily insectivorous, but it will not shy away from indulging in berries and other soft fruits.

The Sardinian warbler's song is a rapid and rattling melody, a sound that has become synonymous with the Mediterranean landscapes where it thrives.

The breeding habits of the Sardinian warbler involve the construction of nests in low shrubbery, where the female lays a clutch of eggs that both parents will tend to.

The Sardinian warbler is part of a superspecies complex, which includes Menetries's warbler and the eastern subalpine warbler. These species share certain characteristics, such as white malar areas and light throats in males, but can be differentiated by other plumage features and their distinct calls.

Primarily insectivorous, the Sardinian warbler supplements its diet with berries and other soft fruits, particularly when insects are less abundant.

The Sardinian warbler is currently listed as Least Concern by the IUCN, indicating that, for now, this species does not face any imminent threats to its survival.

2-6-2017 MONTE CORONA, VALENCIA - HOUSE SPARROW (MALE) (Passer domesticus)

The house sparrow (Passer domesticus) is a member of the sparrow family Passeridae. This small bird typically measures around 16 cm (6.3 in) in length and weighs between 24–39.5 g (0.85–1.39 oz). The species exhibits sexual dimorphism, with females and young birds displaying pale brown and grey plumage, while males are characterized by more vibrant black, white, and brown markings.

Males can be identified by their bright black, white, and brown markings, with a distinctive black bib, white cheeks, and a grey crown. Females lack the striking head patterns of males and are predominantly buffish with softer coloration. Juveniles resemble adult females but are generally paler with less defined markings.

The house sparrow is highly adaptable and can thrive in both urban and rural environments. It is commonly found in close association with human habitation and avoids dense forests, grasslands, polar regions, and deserts far from human development.

Native to Europe, the Mediterranean Basin, and much of Asia, the house sparrow has been introduced to various regions worldwide, including parts of Australasia, Africa, and the Americas, making it one of the most widely distributed wild birds.

House sparrows are social birds, often seen in flocks. They exhibit a range of behaviors, including dust or water bathing and communal roosting. Males are known to be territorial around their nesting sites.

The house sparrow's vocalizations are predominantly variations of a simple chirping call. Males may sing or give an "ecstatic call" during the breeding season, and the species uses a variety of calls for different social interactions.

House sparrows are generally monogamous and may mate for life. They can breed in the season following their hatching and often produce multiple clutches per year, with each clutch containing up to five eggs. Nest sites are varied, with a preference for cavities.

The house sparrow can be confused with other seed-eating birds, such as the Eurasian tree sparrow, which has a chestnut crown and a black cheek patch.

An opportunistic feeder, the house sparrow's diet consists mainly of seeds from grains and weeds, but it also consumes insects and other invertebrates, especially during the breeding season when feeding young.

Despite its widespread distribution and abundance, the house sparrow has experienced declines in some areas. However, it is currently listed as Least Concern on the IUCN Red List.

2-6-2017 MONTE CORONA, VALENCIA - SPECKLED WOOD BUTTERFLY (Pararge aegeria)

Occurs in woodland, gardens and hedgerows. Butterflies often perch in sunny spots, spiralling into the air to chase each other.

The aptly named Speckled Wood flies in partially shaded woodland with dappled sunlight. The male usually perches in a small pool of sunlight, from where it rises rapidly to intercept any intruder. Both sexes feed on honeydew in the treetops and are rarely seen feeding on flowers, except early and late in the year when aphid activity is low.

The range of this butterfly contracted during the late nineteenth and early twentieth centuries but has spread back since the 1920s. It has continued to spread over the past two decades, recolonizing many areas in eastern and northern England and Scotland.

Speckled wood (Pararge aegeria) Understated yet headstrong, the speckled wood spends its time basking in sun-dappled woodland and fiercely patrolling its patch. The pupa is well disguised as a leaf. The speckled wood usually feeds on aphid honeydew, but can feed on fruit.

In Europe there are two main subspecies of Speckled Wood. In the UK we get the paler tircis which is largely found NE of a line from southern England down to the Aegean. SW of this line is the orangey aegeria, with intermediate forms along the transition line including a subspecies endemic to the Isles of Scilly called insula. In warmer years we get more orangey individuals in the UK, so its likely temperature plays a role in this distribution. There is a fourth subspecies found in western Scotland, P. a. oblita.

1-4-2017 MIAMI, FLORIDA - TUFTED TITMOUSE (Baeolophus bicolor)

The Tufted Titmouse, Baeolophus bicolor, is a small, charismatic songbird of North America, belonging to the tit and chickadee family, Paridae. It is easily recognized by its grey upper body, white front, and rust-colored flanks. A distinctive black forehead and a tufted grey crest adorn its head, adding to its spirited appearance.

Adult Tufted Titmice measure between 5.5 to 6.3 inches in length, with a wingspan ranging from 7.9 to 10.2 inches, and weigh between 0.6 to 0.9 ounces. Males are generally larger than females. Juveniles may be identified by their less pronounced black forehead, which can lead to confusion with the Oak Titmouse in areas where their ranges do not overlap.

This species thrives in a variety of wooded environments, including deciduous and mixed forests, as well as human-altered landscapes such as gardens, parks, and shrublands.

Originally native to the Ohio and Mississippi River basins, the Tufted Titmouse has expanded its range due to factors such as the provision of bird feeders. It is now found across the United States and into parts of Ontario and Quebec in Canada. This bird is non-migratory, remaining in its territory year-round.

The Tufted Titmouse is an active forager, often seen gathering food from the ground and tree branches. It consumes a varied diet of berries, nuts, seeds, small fruits, insects, and other invertebrates, with caterpillars being a significant component during the summer months. It is known to visit bird feeders, typically grabbing a seed and retreating to cover to eat. This bird exhibits a notable curiosity towards humans and may investigate human structures in search of prey.

The song of the Tufted Titmouse is a clear, whistled "peter-peter-peter," which can vary in up to 20 notable ways. They are vocal birds, often responding to the sounds of agitation in other birds and forming mixed-species foraging flocks.

Nesting occurs in tree cavities, including natural holes, old woodpecker nests, or human-made nest boxes. Nests are lined with soft materials, and occasionally, snake skin sheds are used as a deterrent to predators. Eggs are white or cream with brownish or purplish spots, and the clutch size averages five to seven eggs. Offspring may stay with their parents through the winter and sometimes assist in raising the next year's brood.

The Tufted Titmouse's diet is diverse, including berries, nuts, seeds, insects, and other small invertebrates. It is a common visitor to bird feeders, where it exhibits a pattern of taking a seed and flying to cover to consume it.

The Tufted Titmouse has experienced a population increase of more than 1.5% per year from 1966 to 2015 in the northeastern U.S. The current breeding population is estimated at around 8 million individuals, and the species is classified as Least Concern by the IUCN.

2-6-2017 MONTE CORONA, VALENCIA - COMMON DARTER DRAGONFLY (FEMALE) (Sympetrum striolatum)

The common darter (Sympetrum striolatum) is a dragonfly of the family Libellulidae native to Eurasia. It is one of the most common dragonflies in Europe, occurring in a wide variety of water bodies, though with a preference for breeding in still water such as ponds and lakes. In the south of its range adults are on the wing all year round.

Sympetrum species are not easy to tell apart and in most areas more than one Sympetrum species will occur. Females and teneral individuals have light yellow thorax and abdomen. Males turn red as they mature. Females darken with age, becoming a dark chocolate brown, and sometimes develop a blue colouration to the bottom of the abdomen. The wings also develop a brown tinge with age. In all cases the legs have a cream or yellow stripe on a black background - this is a diagnostic feature of this species. The pterostigma of the females can be red, blue, pale blue or brown.

Adults can be seen on the wing all year round in southern Europe but in northern regions they occur from June to November.

This small dragonfly is seen in a wide variety of habitats, including lakes, ponds, canals and slow-flowing rivers. They are ambush predators, waiting on a prominent perch - such as a leaf or the top of a gate, until prey fly past, whereupon they will fly after it. They are territorial on breeding waters, often attempting to chase much bigger dragonflies away such as southern hawkers. This habit of repeatedly returning to a sunny spot allows you to easily predict where they are going to land, which is why it is one of the easiest dragonflies to photograph.

In suitable hunting areas away from water, however, they are not territorial: large numbers may assemble - groups of several hundred in a single field have been recorded - and lines of insects can be seen along the top of field gates.

Eggs are not laid, but broadcast from the air: the male holds the female in tandem and swings her down and forward over water. At the furthest point of the arc the female releases some of her eggs to fall on the water.

1-6-2017 MONTE CORONA, VALENCIA - SPOTTED FLYCATCHER (Muscicapa striata)

Spotted flycatchers are one of our summer migrants that spend the winter in Africa. They are one of the latest migrants to reach us, with a few trickling into the country from late April and most arriving from mid-May.

Despite arriving relatively late, spotted flycatchers manage to rear two broods of young before departing at the end of August. The success of the second clutch is increased by fewer eggs being laid, meaning less mouths to fill. They will nest in gardens but the nest is usually well hidden on ledges or behind climbing plants.

Spotted flycatchers prefer large flying insects, including flies and butterflies. However, if the weather is cool and insects aren’t flying, they will take smaller invertebrates from leaves and branches. If poor weather persists, many nests fail as these smaller invertebrates tend to be eaten by the parents rather than fed to the young.

In order to reduce the chances of their invertebrate prey escaping, spotted flycatchers have a series of modified feathers, like bristles, down the sides of the bill. They have also adapted to catch stinging insects. They rub the sting end on their perch to remove it, making the prey safe to eat.

The spotted flycatcher is red listed due to its rapid and consistent population decline with an 89 per cent decrease between 1967 and 2012. Evidence suggests that this is due to poor annual survival rates of first year birds, but conditions in their wintering grounds in Africa may also have contributed to the decline.

Spotted flycatchers are fairly drab birds, with brown-grey upperparts. Below they have dull white plumage with pale streaking, and there is streaking on the head. Juveniles are similar but have pale spots on their upperparts. Despite their dull appearance, they are easy to spot as they like to perch on exposed posts or branches from which they catch their prey.

As well as looking plain, the spotted flycatcher’s song is pretty unremarkable. It is squeaky, mostly unmelodic and very soft. The squeaky part of the song is part of its territorial defence, and the more musical sequences are aimed at potential mates.

1-6-2017 MONTE CORONA, VALENCIA - MOORISH GECKO (Tarentola mauritanica)

Tarentola mauritanica, known as the common wall gecko, is a species of gecko (Gekkota) native to the western Mediterranean area of North Africa and Europe. It has been introduced to Madeira and Balearic Islands, and the Americas (in Montevideo, Buenos Aires and California). A nocturnal animal with a predominantly insectivorous diet, it is commonly observed on walls in urban environments in warm coastal areas; it can be found further inland, especially in Spain where it has a tradition of cohabitation with humans as an insect hunter. A robust species, up to 15 centimetres (5.9 in) long, its tubercules are enlarged and give the species a spiny armoured appearance.

The species was first described by Carl Linnaeus in 1758. It is also known as moorish gecko, crocodile gecko, European common gecko, and, regionally, as osga (in Portuguese), salamanquesa (in Spanish) and dragó (in Catalan).

The Common wall gecko is a small lizard native to the western Mediterranean area of North Africa and Europe. It is commonly observed on walls in urban environments, mainly in warm coastal areas. However, the Common wall gecko can be found further inland, especially in Spain where it has a tradition of cohabitation with humans as insect hunter. This little creature is brownish-grey or brown in color with darker or lighter spots. These colors change in intensity according to the light. When geckos are active by day their color is darker than during the night.

In Europe, Common wall geckos can be found through most of the Iberian Peninsula (except northwestern Portugal and most of northern Spain), southern France, coastal Italy, southern Slovenia, northern coastal Croatia, and southwestern parts of Greece. In North Africa, they range from northern Egypt, through northern Libya, northern and central Tunisia, and northern Algeria to most of Morocco and northwestern Western Sahara. There is an isolated introduced population in southern Western Sahara. Common wall geckos can be found in rocky areas, cliffs, rock fields, and on many construction sites, ruins, building walls, and inside houses.

26-5-2017 MARJOL DE MOROS, VALENCIA - BLUE WINGED GRASSHOPPER (Oedipoda caerulescens)

The blue-winged grasshopper, Oedipoda caerulescens, is a grasshopper in the genus Oedipoda.

This species occurs in Europe, North Africa and Asia. It was recently rediscovered in the Maltese islands.

Oedipoda caerulescens is a medium-sized grasshopper, between 15 and 21 mm for males and between 22 and 28 mm for females. The body coloration varies greatly depending on the substrate on which the animals have developed: reddish brown, gray, yellowish, or even completely dark or bright. The forewings are crossed most often by two or three pale bands, but the most striking characteristic, very visible when the insect flies away, is the bright coloration of the hind wings, a beautiful turquoise highlighted with a black marginal stripe. Furthermore, the posterior femora have a notch on their upper surface. At rest, confusion is possible with other Oedipoda species such as O. germanica.

Subspecies

Oedipoda caerulescens armoricana Sellier, 1948

Oedipoda caerulescens caerulescens (Linnaeus, 1758)

Oedipoda caerulescens nigrothoracica Görtler, 1948

Oedipoda caerulescens sulfurescens Saussure, 1884

Oedipoda caerulescens frequents dry areas with low and open vegetation: dunes, heathlands, grasslands on sand and sunlit limestone rocks. Many stations correspond to land recently used for human activities, such as coal spoil heaps, quarries and pits, the ballast of railway tracks, etc. It is exclusively a terrestrial insect, and its cryptic coloration often matches its substrate. It presses itself to the ground and remains motionless, and jumps only at the very close approach of danger. A remarkable behavior is the "hook" landing which serves to confuse potential attackers. Thus, the grasshopper lands and swings round to face the direction it has come from. The sudden disappearance of the blue hind wings of the adult makes it difficult for predators to shift quickly enough to a different kind of search to relocate the prey. The female lays her eggs in bare, dry soil. In this species, acoustic emissions are virtually nonexistent. The diet consists mainly of grasses.

31-5-2017 MARJAL DE MOROS, VALENCIA - SQUACCO HERON (Ardeola ralloides)

The Squacco Heron, Ardeola ralloides, is a diminutive member of the heron family, measuring a mere 44–47 cm in length, with a compact body of 20–23 cm and a wingspan stretching 80–92 cm. This species is adorned with a buff-brown back and, during the summer months, adults boast elongated neck feathers that add to their allure.

In the field, one may identify the Squacco Heron by its stocky build, abbreviated neck, and stout bill. Its back is cloaked in a buff-brown hue. When in flight, the heron undergoes a remarkable transformation, revealing a predominantly white plumage that contrasts starkly with its resting appearance.

The Squacco Heron favors marshy wetlands in temperate regions for its habitat, where the water is warm and inviting.

Originating from the Old World, the Squacco Heron breeds in the southern reaches of Europe and extends into the Greater Middle East. When not breeding, it migrates to winter in the African continent.

This species is migratory by nature, seeking the warmer climates of Africa to spend the winter. It is seldom seen north of its breeding grounds. The Squacco Heron has been observed as a vagrant in the Fernando de Noronha islands and, on rarer occasions, in mainland South America. It nests in modest colonies, often in the company of other wading birds, and constructs its nests from sticks on platforms in trees or shrubs.

The Squacco Heron selects freshwater locales across Europe and the Middle East to breed, later migrating southward to the Sub-Saharan African region. During the breeding season, they lay a clutch of three to four eggs.

The squacco heron is a migrant, wintering in Africa. It is rare north of its breeding range. The species has been recorded in Fernando de Noronha islands, and more rarely in mainland South America, as a vagrant. This is a stocky species with a short neck, short thick bill and buff-brown back. In summer, adults have long neck feathers. Its appearance is transformed in flight, when it looks very white due to the colour of the wings.

The squacco heron's breeding habitat is marshy wetlands in warm countries. The birds nest in small colonies, often with other wading birds, usually on platforms of sticks in trees or shrubs. Three to four eggs are laid. They feed on fish, frogs and insects.

Adept at foraging, the Squacco Heron feeds on a diet consisting of fish, frogs, and insects, making the most of its wetland environment.

The IUCN Red List currently classifies the Squacco Heron as Least Concern, indicating a stable population without immediate threats to its survival.

Non-breeding Squacco Herons share certain physical characteristics with other heron species such as the Indian Pond Heron and the Malagasy Pond Heron, including tawny plumage, lighter streaking, a smaller bill, and narrower wing tips.

31-5-2017 MARJAL DE MOROS, VALENCIA - PURPLE HERON (Ardea purpurea)

The Purple Heron (Ardea purpurea), a statuesque avian, stands with a height ranging from 70 to 94 cm and boasts a wingspan of 120 to 152 cm. Despite its grand stature, it is a slender creature, tipping the scales at a mere 0.5 to 1.35 kg. This bird is slightly smaller and more svelte than its cousin, the Grey Heron, and is adorned with darker, reddish-brown plumage.

Adult Purple Herons are distinguished by their black foreheads and crowns, with a dark stripe cascading down the back of the neck, culminating in a modest, dangling crest. Their heads and necks are a buffish chestnut, streaked with dark lines, while the mantle dons an oily brown hue. The upper parts and tail are a brownish grey, and the underparts are a mix of chestnut and black. During the breeding season, the beak of the adult brightens, and the eyes gleam with a yellow iris.

The Purple Heron is a denizen of marshes, lagoons, and lakes, often shrouded by dense vegetation. It has a penchant for freshwater habitats, particularly those with expansive reed beds of Phragmites. Coastal mangrove swamps are also within its realm, though less frequently visited.

This heron has a broad range that spans Africa, central and southern Europe, and the southern and eastern Palearctic. While the Western Palearctic populations are migratory, their African and tropical-Asian counterparts are mostly sedentary, save for occasional dispersive movements.

The Purple Heron is a creature of stealth and grace, often retreating to the sanctuary of reed beds. It exhibits a slow, deliberate flight, with its neck retracted and legs trailing behind. On land, it moves with long toes that allow it to traverse floating vegetation or even bushwalk without grasping the branches. Dawn and dusk are its preferred times for activity, with the bird often seen stalking or standing in ambush for its prey.

The heron's vocalization is a subdued "frarnk," a quieter and higher-pitched affair compared to the Grey Heron. It is generally less vocal, but similar guttural sounds may emanate from its colonies.

Purple Herons are colonial breeders, constructing bulky nests from dead reeds or sticks in close proximity to water. They lay about five bluish-green eggs, with both parents sharing incubation duties. The young emerge after approximately four weeks and take their first flight six weeks later.

The Grey Heron (Ardea cinerea) is the most similar species, but the Purple Heron can be differentiated by its smaller size, darker plumage, and the shorter crest on its head.

A versatile predator, the Purple Heron's diet includes fish, rodents, frogs, insects, and more. It employs both stalking and ambush tactics to capture its prey, often waiting motionlessly or slowly stalking its victim.

The International Union for Conservation of Nature (IUCN) has classified the Purple Heron as "Least Concern," despite a global population trend that is on the decline. The primary threat to this species is the drainage and disturbance of wetland habitats, particularly the destruction of reed beds.

31-5-2017 MARJAL DE MOROS, VALENCIA - LITTLE EGRET (Egretta garzetta)

The little egret (Egretta garzetta) is a species of small heron in the family Ardeidae. It is a white bird with a slender black beak, long black legs and, in the western race, yellow feet. As an aquatic bird, it feeds in shallow water and on land, consuming a variety of small creatures. It breeds colonially, often with other species of water birds, making a platform nest of sticks in a tree, bush or reed bed. A clutch of three to five bluish-green eggs is laid and incubated by both parents for about three weeks. The young fledge at about six weeks of age.

Its breeding distribution is in wetlands in warm temperate to tropical parts of Europe, Africa, Asia, and Australia. A successful colonist, its range has gradually expanded north, with stable and self-sustaining populations now present in the United Kingdom.

Little egrets are sociable birds and are often seen in small flocks. They are diurnal birds and feed mainly in the early morning and in the late afternoon. They use a variety of methods to procure their food; they stalk their prey in shallow water, often running with raised wings or shuffling their feet to disturb small fish, or may stand still and wait to ambush prey. Little egrets also make use of opportunities provided by cormorants disturbing fish or humans attracting fish by throwing bread into the water. On land, they walk or run while chasing their prey, feed on creatures disturbed by grazing livestock and ticks on the livestock, and even scavenge occasionally. Little egrets are silent birds in general, however, at their breeding colonies, they make various croaking and bubbling calls. When disturbed, they produce a harsh alarm call.

Little egrets are monogamous. This means that males and females mate only with one partner. They nest in colonies, often with other wading birds. The nests are usually platforms of sticks built in trees or shrubs or in reed beds or bamboo groves. In some locations such as the Cape Verde Islands, these birds nest on cliffs. Pairs defend a small breeding territory, usually extending around 3 to 4 m (10 to 13 ft) from the nest. The female lays 3 to 5 eggs which are incubated by both parents for 21 to 25 days. The eggs are oval in shape and have a pale, non-glossy, blue-green shell color. Upon hatching the chicks are covered in white down feathers and are cared for by both parents. Around 3 weeks after hatching the chicks start to move around the nest and climb into the close branches. They fledge after 40 to 45 days and are able to follow the adults to learn how to feed themselves.

31-5-2017 MARJAL DE MOROS, VALENCIA - OLD WORLD SWALLOWTAIL BUTTERFLY (Papilio machaon)

Papilio machaon, the Old World swallowtail, is a butterfly of the family Papilionidae. The butterfly is also known as the common yellow swallowtail or simply the swallowtail (a common name applied to all members of the family, but this species was the first to be given the name). It is the type species of the genus Papilio. This widespread species is found in much of the Palearctic (it is the only swallowtail in most of Europe) and in North America.

This butterfly is present throughout the entire Palearctic region, ranging from Russia to China and Japan, (including the Himalayas and Taiwan), and across into Alaska, Canada, and the United States, and thus, is not restricted to the Old World, despite the common name. In Asia, it is reported as far south as Saudi Arabia, Oman, the high mountains of Yemen, Lebanon, Iran and Israel. In southern Asia, it occurs in Pakistan and Kashmir, northern India (Sikkim, to Assam, and Arunachal Pradesh), Nepal, Bhutan, and northern Myanmar.

This butterfly is widespread in Europe. In the United Kingdom, it is limited to a few areas in the Norfolk Broads of East Anglia. It is the UK's largest resident butterfly. The monarch (Danaus plexippus) is slightly larger, but is only a rare vagrant.

As P. machaon is widespread throughout Eurasia and often common, it is not threatened as a species. It is listed as "vulnerable" in the South Korean and Austrian Red Data Books, and in the Red Data Book of the former Soviet Union. In Armenia the species demonstrates stable population trend and is assessed as Least Concern.

There are usually two to three broods in a year, but in northern areas, the species may be univoltine. In some places such as the UK, some will pupate and emerge in the same year and others will overwinter as pupae before emerging the following year, a situation known as being partially bivoltine.

The caterpillar spends the first part of its life with the appearance of a bird dropping, an effective defense against predators. As the caterpillar grows larger, it becomes green with black and orange markings. It has a defense against predators in the form of an osmeterium, which consists of retractable, fleshy projections behind its head that can release a foul smell if disturbed, which deters insects, but not birds.

31-5-2017 MARJAL DE MOROS, VALENCIA - LITTLE TERN (Sternula albifrons)

The little tern (Sternula albifrons ) is a seabird of the family Laridae. It was formerly placed into the genus Sterna, which now is restricted to the large white terns. The genus name is a diminutive of Sterna, "tern". The specific albifrons is from Latin albus, "white", and "frons", forehead. The former North American (S. a. antillarum ) and Red Sea S. a. saundersi subspecies are now considered to be separate species, the least tern (Sternula antillarum ) and Saunders's tern (Sternula saundersi ).

This bird breeds on the coasts and inland waterways of temperate and tropical Europe and Asia. It is strongly migratory, wintering in the subtropical and tropical oceans as far south as South Africa and Australia.

There are three subspecies, the nominate albifrons occurring in Europe to North Africa and western Asia; guineae of western and central Africa; and sinensis of East Asia (SE Russia to Japan, SE Asia, Philippines) and the north and east coasts of Australia and New Guinea

The little tern breeds in colonies on gravel or shingle coasts and islands. It lays two to four eggs on the ground. Like all white terns, it is defensive of its nest and young and will attack intruders.

Like most other white terns, the little tern feeds by plunge-diving for fish, usually from saline environments. The offering of fish by the male to the female is part of the courtship display.

This is a small tern, 21–25 cm long with a 41–47 cm wingspan. It is not likely to be confused with other species, apart from fairy tern and Saunders's tern, because of its size and white forehead in breeding plumage. Its thin sharp bill is yellow with a black tip and its legs are also yellow. In winter, the forehead is more extensively white, the bill is black and the legs duller. The call is a loud and distinctive creaking noise.

The little tern was described by the German naturalist Peter Simon Pallas in 1764 and given the binomial name Sterna albifrons.

The Kentish plover, Anarhynchus alexandrinus, is a diminutive wader of the family Charadriidae. It is a bird of saline lakeshores, lagoons, and coastal regions, where it frequents sand dunes, marshes, semi-arid deserts, and tundra. Exhibiting sexual dimorphism, both sexes have pale plumage with a white underside and a grey/brown back, but males are distinguished by dark incomplete breast bands and head markings.

Adult Kentish plovers possess dark legs and bills. Males, during the breeding season, are adorned with a black head bar, dark breast bands, black ear coverts, and a rufous nape and crown, though variations exist among populations. Females are paler and lack the dark markings. As the breeding season wanes, the differences between sexes diminish. Males typically have longer tarsi and flank feathers, the latter being advantageous for incubation and brood care.

Kentish plovers select breeding habitats with low elevation, sparse vegetation, and high moisture, away from human disturbance. They show a preference for open, moist nesting sites and are known to move chicks to areas with better food availability.

This species boasts a vast geographical range, from North Africa to Central Asia and Europe. It is found in countries such as Senegal, China, Spain, and Austria. Some populations are migratory, wintering in Africa, while others, including various island populations, are resident.

Kentish plovers are ground-nesting birds with a flexible breeding system that includes monogamous and polygamous pairings. They exhibit territorial behavior, with males attracting females through courtship displays. Parents may move chicks to improve survival chances, balancing the risks and benefits of such movements.

The Greater flamingo (Phoenicopterus roseus) is the most widespread and largest species of the flamingo family. It was described by Peter Simon Pallas in 1811. The Greater flamingo was previously thought to be the same species as the American flamingo, but because of coloring differences of its head, neck, body, and bill, the two flamingos are now most commonly considered separate species.

Greater flamingos have an attractive coloration and appearance. Their feathers are pinkish/white, the wing coverts are red and the primary and secondary flight feathers are black. They have long pink bills with a black tip, yellow eyes and long pink legs. The male is bigger than the female, and juveniles have a gray-brown coloration, with some pink on their underparts, tail and wings, with the legs and beak being mainly brown.

The Greater flamingo inhabits Africa, the Middle East, southern Europe, and the Indian subcontinent. They occur in relatively shallow water bodies, such as saline lagoons, salt pans, large alkaline or saline lakes, and estuaries. Breeding takes place on sandbanks, mudflats, sandy or rocky islands, or open beaches.

Greater flamingos are very social. They travel in groups numbering up to thousands and they communicate by using visual and auditory cues. Greater flamingos are partially dispersive and migratory. They are traveling constantly, seeking areas with enough resources to sustain the whole flock, especially during the mating season. Greater flamingos keep their chicks together in crèches. Adults supervising crèches tend to act in a hostile way toward hatchlings if their own young are not in that crèche. Greater flamingos are diurnal, feeding during the day. Being bottom feeders, they rely on water levels that are low, and they move to new areas to find appropriate feeding conditions. They often bathe in fresh shallow water and preen their feathers to remove salt from them. They are not territorial birds but during breeding season they do defend their nests.

31-5-2017 MARJAL DE MOROS, VALENCIA - COMMON TERN (Sterna hirundo)

The Common Tern, Sterna hirundo, is a slender seabird with a circumpolar distribution, breeding in temperate and subarctic regions of Europe, Asia, and North America. It is a migratory species, wintering in coastal tropical and subtropical regions. Adults display light grey upperparts, white to very light grey underparts, and a black cap. Their legs are orange-red, and they possess a narrow pointed bill, which varies in color between subspecies.

To identify the Common Tern, look for its pale grey upper wings, which develop a dark feather shaft as the season progresses, creating a grey wedge. The rump and tail are white, and the tail extends no further than the folded wingtips when the bird is standing. The bill is mostly red with a black tip or entirely black, depending on the subspecies. In non-breeding adults, the forehead and underparts become white, and the bill turns black.

Common Terns are found nesting on flat, poorly vegetated surfaces close to water, such as beaches, islands, and artificial substrates like floating rafts. They adapt to a variety of habitats, from the taiga to tropical shores, and avoid excessively rainy, windy, or icy areas.

This species has a wide breeding range, encompassing Europe, North Africa, Asia, and North America. It migrates to winter along the coasts of Central and South America, Africa, and southern Asia, with some populations remaining partially migratory in the Caribbean.
