8-7-2020 ULLAL DE BALDOVI, ALBUFERA - BLACK CROWNED NIGHT HERON (Nycticorax nycticorax)

The Black-crowned Night Heron, scientifically known as Nycticorax nycticorax, is a medium-sized heron with a global presence, spanning parts of Europe, Asia, and the Americas. It is distinguished by its black crown and back, contrasting with a white or grey body, red eyes, and short yellow legs. Notably, it deviates from the typical heron silhouette, appearing more robust with shorter bills, legs, and necks compared to its egret and day heron relatives.

Adults boast a striking black crown and back, with the rest of their plumage primarily white or grey. Their eyes are a vivid red, and they stand on short yellow legs. During social interactions, such as greeting or courtship, they display two or three elongated white plumes that extend from the back of their heads. Males and females are similar in appearance, though males may be marginally larger. Juveniles, on the other hand, are cloaked in a dull grey-brown with pale spots and streaks, and their eyes are a more subdued orange with less vibrant legs.

These herons favor fresh and salt-water wetlands as their breeding grounds, which are found across their vast range.

The Black-crowned Night Heron breeds across various regions: from Eurasia to Africa, the Indonesian Archipelago, North and South America, and even the remote Falkland Islands. While migratory in the northern extremes, it is generally a resident species, with North American populations wintering in warmer climes from Mexico to the West Indies.

8-7-2020 ULLAL DE BALDOVI, ALBUFERA - NOMAD DRAGONFLY (MALE) (Sympetrum fonscolombii)

The red-veined darter or nomad (Sympetrum fonscolombii) is a dragonfly of the genus Sympetrum.

Sympetrum fonscolombii was named under the protonym Libellula fonscolombii by the Belgian entomologist Edmond de Sélys Longchamps, in 1840, in honor of the French entomologist Étienne of Fonscolombe (hence the species name). Its name is sometimes spelt fonscolombei instead of fonscolombii but Askew (2004) gives the latter as the correct spelling.

Sympetrum fonscolombii can reach a body length of 38–40 millimetres (1.5–1.6 in). This species is similar to other Sympetrum species but a good view with binoculars should give a positive identification, especially with a male.

Males have a red abdomen, redder than many other Sympetrum species. The frons and the thorax are red-brown. The eyes are brown above and blue/grey below. The wings have red veins and the wing bases of the hind-wings are yellow. The pterostigma is pale yellow with a border of black veins.

Female are similar but the abdomen is ochre yellow, not red, with two black lines along each side. The wings have yellow veins at the costa, leading edge and base, not red veins as found in the males. The legs of both sexes are mostly black with some yellow.

Immature males are like females but often with more red and a single line along each side of the abdomen.

Male S. fonscolombii can be mistaken for Crocothemis erythraea as both are very red dragonflies with yellow bases to the wings, red veins and pale pterostigma. However C. erythraea has no black on the legs, a broader body and no black on the head. Also C. erythraea females do not oviposit in tandem. The gestalt image of these two species is different and with some experience are easy to tell apart.

8-7-2020 ULLAL DE BALDOVI, ALBUFERA - BARN SWALLOW (Hirundo rustica)

The barn swallow (Hirundo rustica) is a migratory passerine bird, recognized as the most widespread species of swallow in the world. It is a distinctive bird with blue upperparts and a long, deeply forked tail, known for its graceful flight and agile maneuvers. The adult male of the nominate subspecies is 17–19 cm in length, including elongated outer tail feathers, and has a wingspan of 32–34.5 cm. It is adorned with a rufous forehead, chin, and throat, which are set apart from the off-white underparts by a broad dark blue breast band. The outer tail feathers are elongated, contributing to the iconic "swallow tail."

The barn swallow can be identified by its steel blue upperparts, a rufous face, and a dark blue breast band that separates the rufous from the off-white underparts. The deeply forked tail is a key characteristic, with a line of white spots across the upper tail's outer end. Females resemble males but have shorter tail streamers and less glossy blue coloring. Juveniles are browner with paler rufous faces and whiter underparts, lacking the adult's long tail streamers.

The barn swallow favors open country with low vegetation, such as pastures, meadows, and farmland, often near water. It avoids heavily wooded or steep areas and densely built-up locations. The species typically nests in man-made structures like barns and stables, or under bridges and wharves.

10-7-2020 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.

8-7-2020 RACO DE OLLA, VALENCIA - COMMON TERN (Sterna hirundo)

The Common tern (Sterna hirundo) is a seabird that has a circumpolar distribution. it has four subspecies breeding in temperate and subarctic regions of Europe, Asia, and North America. Its large population and huge breeding range mean that this species is classed as being of least concern, although numbers in North America have declined sharply in recent decades.

Known for its attractive plumage and graceful flight, Common terns have a slender body and a smoothly rounded head, and long pointed wings. Their breeding plumage is light silvery-gray upperparts and clear black outer primaries on its wingtips. Outside the breeding season, the birds keep some of their distinguishable black cap, but their forehead and face turn white. Their legs and bill turn black, losing their orange-red coloration. Male and female are similar in appearance throughout the year. Juvenile Common terns have pale grey upper wings with a dark carpal bar. The crown and nape are brown, and the forehead is ginger, wearing to white by autumn. The upper parts are ginger with brown and white scaling, and the tail lacks the adult's long outer feathers. Birds in their first post-juvenile plumage, which normally remain in their wintering areas, resemble the non-breeding adult but have a duskier crown, dark carpal bar, and often very worn plumage. By their second year, most young terns are either indistinguishable from adults, or show only minor differences such as a darker bill or white forehead.

Common terns occur from northern Canada to the Caribbean Sea in the south, throughout Europe, Northern Asia, the Middle East and North Africa. Outside of the mating season, these birds winter along the coasts of South America and Central America, along Africa’s coast and the Arabian Peninsula, as well as on islands in the Indian Ocean and throughout Australasia and much of Southeast Asia. They breed on sand spits, beaches and low-lying inshore islands. They also nest inland near slow-flowing rivers, and lakes in open country. This species favors areas that have close shallow waters where they can fish. During migration, they are mainly seen along coasts, at freshwater inland lakes and in estuaries. During winter, they are mostly coastal, in warm tropical and subtropical waters.

Common terns are diurnal birds and they live in colonies with no clear hierarchy among them, with all seeming to be equal. Although Common terns all migrate and live together, the family unit is responsible to feed and care for its own eggs and chicks, and individuals will often defend feeding territories. This species forages by flying above water and hovering, often plunge-diving to catch prey under the surface. It will also swim as it picks up food from the surface of the water or just below it. A highly migratory bird, it leaves the breeding grounds for the wintering sites typically from August to October, soon after all the chicks fledge. These birds communicate mostly by means of their unusual, hoarse voices, having three different and distinct calls. Communication during mating is mainly visual and/or tactile.

8-7-2020 RACO DE OLLA, VALENCIA - COMMON SHELDUCK (FEMALE) (Tadorna tadorna)

The common shelduck, Tadorna tadorna, is a waterfowl species that graces the Euro-Siberian region with its presence. It is a medium-sized bird, akin to a small, short-necked goose, and is quite the sight with its white plumage contrasted by chestnut patches and a black underbelly. The head and neck are a dark, iridescent green, and the bill is a reddish-pink, with the male sporting a conspicuous knob on the forehead during the breeding season. Pink feet complete the ensemble, making this bird a striking figure in its habitat.

To identify the common shelduck, look for the distinctive reddish-pink bill and pink feet. The male, especially in breeding plumage, has a bright red bill with a prominent knob. The female is slightly smaller and has white facial markings. Both sexes have a white body with chestnut patches, a black belly, and a dark green head and neck. In flight, the green and chestnut secondary feathers become visible, contrasting with the predominantly white underwings.

The common shelduck is found in a variety of wetland habitats, including temperate lakes and rivers, as well as estuaries and tidal mudflats in winter. It has a particular fondness for salt marshes and estuaries and is known to breed in rabbit burrows, tree holes, and even haystacks.

This species is widespread across temperate Eurasia. It breeds in temperate regions and migrates to subtropical areas for wintering. Some populations remain resident in the westernmost parts of Europe, while others undertake movements to moulting grounds like the Wadden Sea.

The common shelduck is a sociable bird, often seen in large moulting flocks that can number up to 100,000 individuals. It is known for leaving its young in crèches supervised by a few adults. The species is also covered by the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA), highlighting its ecological importance.

The vocalization of the common shelduck is a loud, unmistakable honk, which can be heard over considerable distances.

During the breeding season, the male's bill becomes particularly vibrant, and the species is known to nest in a variety of locations, from rabbit burrows to tree holes.

While the common shelduck is quite distinctive, it could potentially be confused with other shelduck species. However, its unique coloration and size generally make it easy to distinguish.

The common shelduck feeds on a variety of items, including mollusks and small aquatic creatures, which it often forages for in the mudflats during low tide.

The IUCN Red List classifies the common shelduck as Least Concern, indicating that, currently, there are no immediate threats to its population numbers on a global scale.

8-7-2020 L'ESTANY DE CULLERA, VALENCIA - MALLARD (MALE) (Anas platyrhynchos)

The Mallard, or wild duck (Anas platyrhynchos), is a familiar and widespread dabbling duck with a presence across temperate and subtropical regions of the Americas, Eurasia, and North Africa. It has also been introduced to parts of the Southern Hemisphere. The male is renowned for its iridescent green head and white collar, while the female sports a brown-speckled plumage. Both sexes boast a speculum—a patch of feathers with iridescent purple or blue hues bordered by white. The Mallard's length ranges from 50 to 65 cm, with a wingspan of 81 to 98 cm, and it typically weighs between 0.7 and 1.6 kg.

Males during the breeding season are unmistakable with their glossy green heads, white collars, and purple-tinged brown breasts. Females are mottled brown with buff cheeks and an eye-stripe. Both sexes have the distinctive speculum on their wings. The male's bill is yellowish-orange tipped with black, while the female's is darker, ranging from black to mottled orange and brown.

Mallards are found in a variety of wetlands, including parks, small ponds, rivers, lakes, and estuaries. They prefer water depths less than 0.9 meters and are drawn to areas with aquatic vegetation.

8-7-2020 L'ESTANY DE CULLERA, VALENCIA - EURASIAN COOT (FEMALE AND JUVENILE) (Fulica atra)

The Eurasian coot is found on freshwater lakes and ponds and has adapted well to urban environments, often seen in city parks and gardens with water bodies.

This bird has a broad range across the Old World, including Europe, Asia, Australia, New Zealand, and parts of North Africa. It is a resident in milder regions but migrates south and west from much of Asia during winter.

The Eurasian coot is less secretive than many rails, often visible on open water or grasslands. It is territorial and aggressive during the breeding season, with both parents defending their territory. In non-breeding seasons, coots may form large flocks. They are reluctant flyers, preferring to run across water surfaces, and are known for bobbing their heads while swimming.

This species is known for its noisy demeanor, producing a variety of crackling, explosive, or trumpeting calls, which are often heard at night.

Coots build bulky, sometimes floating nests, concealed in vegetation or in the open. Both sexes construct the nest, with the male gathering materials. Clutches typically contain 6-10 buff-colored eggs speckled with black or dark brown. Both parents incubate the eggs, which hatch after 21-24 days. Chicks are precocial and nidifugous, with distinctive orange-red tips on their down.

2-7-2020 ROSSELL, CASTELLON - ROCK GRAYLING BUTTERFLY (Hipparchia alcyone)

The Rock Grayling (Hipparchia alcyone or H. semele) is a master-camouflage butterfly found in dry, rocky, and woodland habitats across Europe, particularly in the south and Finland. It rarely shows its dark brown and orange-spotted upper wings, preferring to keep them closed to blend into stones or bark.

Key Facts about the Rock Grayling Butterfly

Camouflage Specialist: Their wings have an intricate grey-and-black pattern underneath (cryptic coloring) that mimics bark or stone, making them nearly invisible when resting.

Behavior: They almost never open their wings, preferring to sit in sunny spots to regulate body temperature.Habitat: They favor warm, dry environments, particularly pine woods, oak groves, and rocky areas, often seen in southern Europe and mountainous regions (up to 1900 m).

Diet: Caterpillars feed on grasses such as Festuca and Arrhenatherum.

Life Cycle: They are univoltine, meaning they produce one generation per year, flying from June to August.

Identification: They have a large wingspan (\(4.6 - 6\text{ cm}\)) and feature prominent black "eyespots" with white centers on their forewings, used to startle predators.

Conservation: While not immediately threatened globally, their populations are experiencing declines, particularly in northern Europe.
