14-12-2021 SOLLANA, ALBUFERA - WHITE WAGTAIL (Motacilla alba)

The White Wagtail (Motacilla alba) is a small, elegant passerine bird, a member of the family Motacillidae, which includes pipits and longclaws. This slender bird measures between 16.5 to 19 cm in length, with East Asian subspecies reaching up to 21 cm. It is characterized by its long, constantly wagging tail, a behavior that has become synonymous with the genus. Weighing an average of 25 g, the White Wagtail can live up to 12 years in the wild.

Adult White Wagtails exhibit a distinctive plumage with a combination of grey, black, and white. The bird's upper parts are generally grey, with a white face, belly, and breast. Males during the breeding season may show a darker back, and the species is known for its sharp, brisk call and more melodious song during courtship.

The White Wagtail is commonly found in open country, often in close proximity to human habitation and water sources. It shows a preference for bare areas which facilitate the sighting and pursuit of prey. This bird has adapted well to urban environments, utilizing paved areas such as parking lots for foraging.

14-12-2021 SOLLANA, ALBUFERA - LITTLE EGRET (Egretta garzetta)

The Little Egret, Egretta garzetta, is a dainty heron adorned in pure white plumage. It is characterized by a slender black beak, long black legs, and, notably in the western race, yellow feet. This elegant bird is a sight to behold with its graceful neck and poised stance.

Adult Little Egrets measure between 55–65 cm in length with a wingspan of 88–106 cm, and weigh 350–550 g. Their plumage is predominantly white, though some may exhibit bluish-grey coloration. Breeding adults boast ornate nape plumes reaching about 150 mm, along with distinctive feathers on the breast and elongated scapulars. The bill and lores are black, with greenish-grey skin at the base of the lower mandible and around the eye, which houses a yellow iris. Legs are black with contrasting yellow feet, though juveniles may have greenish-black legs and duller feet. The subspecies E. g. nigripes is distinguished by yellow skin between the bill and eye, and blackish feet.

15-12-2021 MONTE CORONA, VALENCIA - CUTWORM AND DART MOTH (Ammopolia witzenmanni)

Ammopolia witzenmanni is a rare, medium-sized moth belonging to the family Noctuidae. Endemic to the Mediterranean, it is a monotypic genus (the only species in its genus) primarily found in dry evergreen sclerophyll and Mediterranean shrublands across France, Spain, and North Africa.

Taxonomic and Physical Profile

Classification: Insecta (class) > Lepidoptera (order) > Noctuidae (family) > Xylenini (tribe).Wingspan: 38 to 44 mm.

Appearance: Features grayish-brown forewings with intricate, darker markings and significantly lighter, often whitish hindwings.

Discovery: Originally described as Orthosia witzenmanni in 1890 by Richard Standfuss, it was later designated as the type species for the new genus Ammopolia by Charles Boursin in 1955.

Habitat and Ecology

Distribution: Primarily inhabits the Mediterranean basin. You can find detailed occurrences mapped out globally on the GBIF Occurrence Data.

Host Plants: Larvae feed on specific Mediterranean woody plants, such as the evergreen buckthorn (Rhamnus alaternus).

Ecology: The seasonal activity of these insects strongly ties to the availability of new leaf flushes in spring, making them a specialized part of Mediterranean evergreen and relict forests.

15-12-2021 ADOR CAMPO, VALENCIA - COMMON CHAFFINCH (MALE) (Fringilla coelebs)

The Eurasian chaffinch, or simply the chaffinch (Fringilla coelebs), presents a striking dichotomy in plumage between the sexes. The male is resplendent with a blue-grey cap and rust-red underparts, while the female's attire is more subdued, though both genders boast two white wing bars and white sides to their tails. The male's robust voice is a herald of spring, as he sings from exposed perches to court a mate.

To identify the male chaffinch, look for the black forehead, blue-grey crown, and rust-red breast, which fades to a pale creamy-pink on the belly. The wings feature a white panel on the coverts and a buff-white bar on the secondaries and inner primaries. Females and juveniles are more muted with grey-brown shades above and paler below, but retain the distinctive wing markings.

Chaffinches favor wooded environments, thriving in areas where the July isotherm ranges from 12 to 30°C. They are adaptable, however, and can be found in a variety of forested landscapes across their range.

This small passerine bird is widespread across Europe and parts of Asia, extending to Siberia. It is also an introduced species in some regions, such as New Zealand and South Africa.

Chaffinches are gregarious outside the breeding season, forming flocks in open countryside. They exhibit partial migration, with birds in colder regions moving south for the winter, while those in milder areas may remain sedentary.

The male chaffinch's song is a delightful mix of trills and chirps, with regional dialects adding to the chorus. Each male typically has a repertoire of two or three song types.

Monogamous by nature, chaffinches breed once they reach one year of age. The female meticulously constructs a nest in the fork of a tree, laying a clutch of 4-5 eggs that hatch in about 13 days. The fledglings take to the wing approximately 14 days later but continue to receive parental care for several weeks thereafter.

During the breeding season, chaffinches forage in trees for invertebrates, particularly caterpillars, to feed their young. Outside this period, their diet shifts to seeds and plant material found on the ground.

With its large numbers and expansive range, the Eurasian chaffinch is classified as of Least Concern by the International Union for Conservation of Nature. There is no evidence of significant population declines at present.

Chaffinches must be vigilant against a variety of predators, including crows and squirrels, which may prey upon their eggs and nestlings. They are also susceptible to parasites such as the protozoal Trichomonas gallinae and the Fringilla coelebs papillomavirus, which can cause tumors on their feet and legs.

14-12-2021 SOLLANA, ALBUFERA - 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.

14-12-2021 SOLLANA, ALBUFERA - HOUSE SPARROW (FEMALE) (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.

14-12-2021 ULLAL DE BALDOVI, ALBUFERA - WESTERN SWAMPHEN (Porphyrio porphyrio)

https://www.inaturalist.org/taxa/475028-Porphyrio-porphyrio

14-12-2021 MUNTANYETA DEL SANS, ALBUFERA - 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.

This species boasts a broad range, encompassing southern Europe, Africa (excluding deserts and rainforests), and southern Asia, extending to northern Australia. It is largely sedentary, though certain East Asian populations undertake migrations to warmer climes in winter.

These birds are predominantly insectivorous and may be observed in small flocks. The breeding season is timed with the rains, and in many regions, the Zitting Cisticola is known to produce two broods annually. Males display polygynous tendencies, though monogamous pairings are not uncommon. The male initiates nest construction within the grasses and performs a specialized display to attract females, who then complete the nest.

The male's breeding season is marked by a distinctive flight display, punctuated by a series of "zitting" calls reminiscent of the sound of scissors snipping.

Nests are artfully constructed with living leaves woven into a soft matrix of plant down, cobwebs, and grass. The structure is cup-shaped with an overhead canopy for camouflage. Females lay 3 to 6 eggs and are solely responsible for incubation, which lasts approximately 10 days. Multiple broods may be raised in a single season.

Their diet consists primarily of insects, which they forage for within their grassland habitats.

14-12-2021 EL PALMAR, ALBUFERA - EURASIAN HOOPOE (Upupa epops)

The Eurasian hoopoe, with its scientific name Upupa epops, is a bird of unmistakable appearance. It boasts a warm cinnamon plumage, contrasted by striking black and white wings, and a prominent black-tipped, fan-like crest which it can raise and lower. Its tail features a broad white band across a black background. The hoopoe's long, narrow bill curves downwards, adept for probing the soil, and is black with a fawn base.

When identifying the Eurasian hoopoe, look for its unique silhouette, characterized by its long, tapering bill and erectile crest. In flight, its broad and rounded wings display a bold black and white pattern, and its undulating flight is reminiscent of a large butterfly. The hoopoe's size ranges from 25 to 32 cm in length, with a wingspan of 44 to 48 cm, and it weighs between 46 and 89 grams.

While the hoopoe's appearance is quite distinctive, its call can be confused with that of the Himalayan cuckoo in certain regions.

The hoopoe's diet consists mainly of insects, but it may also consume small reptiles, frogs, seeds, and berries. It uses its bill to probe the soil for larvae, pupae, and insects, which are then beaten against a surface to remove indigestible parts.

The Eurasian hoopoe is classified as "Least Concern" by the IUCN. However, there has been a noted decline in populations since 2008, attributed to habitat loss and over-hunting in certain areas. Conservation efforts are in place in regions where the species is threatened.

14-12-2021 EL PALMAR, ALBUFERA - SMALL WHITE BUTTERFLY (Pieris rapae)

Pieris rapae is a small-to-medium-sized butterfly species of the whites-and-yellows family Pieridae. It is known in Europe as the small white, in North America and the United Kingdom as the cabbage white or cabbage butterfly, on several continents as the small cabbage white, and in New Zealand as the white butterfly. The butterfly is recognizable by its white color with small black dots on its wings, and it can be distinguished from P. brassicae by the latter's larger size and black band at the tip of the forewings.

The caterpillar of this species, often referred to as the "imported cabbageworm", is a pest to crucifer crops such as cabbage, kale, bok choy and broccoli. Pieris rapae is widespread in Europe and Asia; it is believed to have originated in the Eastern Mediterranean region of Europe and to have spread across Eurasia thanks to the diversification of brassicaceous crops and the development of human trade routes. Over the past two centuries, it spread to North Africa (about 1800), North America (1860s), Hawaii (1897), New Zealand (1930), and Australia (1937), as a result of accidental introductions.

14-12-2021 EL PALMAR, ALBUFERA - COMMON SANDPIPER (Actitis hypoleucos)

The Common Sandpiper, Actitis hypoleucos, is a small wader of the Palearctic region, easily recognized by its greyish-brown upperparts and pristine white underparts. Adults typically measure between 18-20 cm in length, with a wingspan of 32-35 cm. They possess short, dark-yellowish legs and feet, and a bill that is pale at the base with a dark tip.

In the field, look for the Common Sandpiper's distinctive stiff-winged flight pattern, just above the water's surface. During the non-breeding season, they appear duller and exhibit more noticeable barring on the wings, which is most visible at close range. Juveniles display heavier barring above and buff edges to their wing feathers. The species can be differentiated from the similar Spotted Sandpiper by its darker legs and feet and the crisper wing pattern, especially in flight.

These birds are often found near freshwater sources, where they nest on the ground in close proximity to the water's edge.

The Common Sandpiper breeds across much of temperate and subtropical Europe and Asia. It is a migratory bird, wintering in Africa, southern Asia, and Australia. During migration, large numbers may congregate in stop-over locations such as Palau in Micronesia.

Common Sandpipers are typically solitary or found in small groups. They may form larger flocks during migration or at breeding season roosts but seldom join multispecies flocks.

When breeding, these birds nest on the ground near freshwater. A notable behavior is the young's ability to cling to a parent's body, being flown to safety when threatened.

14-12-2021 SOLLANA, ALBUFERA - EURASIAN KESTREL (Falco tinnunculus)

The common kestrel (Falco tinnunculus), also known as the European kestrel, Eurasian kestrel or Old World kestrel, is a species of predatory bird belonging to the kestrel group of the falcon family Falconidae. In the United Kingdom, where no other kestrel species commonly occurs, it is generally just called "kestrel".

This species occurs over a large native range. It is widespread in Europe, Asia and Africa, as well as occasionally reaching the east coast of North America. It has colonized a few oceanic islands, but vagrant individuals are generally rare; in the whole of Micronesia for example, the species was only recorded twice each on Guam and Saipan in the Marianas.

In the cool-temperate parts of its range, the common kestrel migrates south in winter; otherwise it is sedentary, though juveniles may wander around in search for a good place to settle down as they become mature. It is a diurnal animal of the lowlands and prefers open habitat such as fields, heaths, shrubland and marshland. It does not require woodland to be present as long as there are alternative perching and nesting sites like rocks or buildings. It will thrive in treeless steppe where there are abundant herbaceous plants and shrubs to support a population of prey animals. The common kestrel readily adapts to human settlement, as long as sufficient swathes of vegetation are available, and may even be found in wetlands, moorlands and arid savanna. It is found from the sea to the lower mountain ranges, reaching elevations up to 4,500 m (14,800 ft) ASL in the hottest tropical parts of its range but only to about 1,750 m (5,740 ft) in the subtropical climate of the Himalayan foothills.

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.

The common kestrel'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.

14-12-2021 SOLLANA, ALBUFERA - WOOD SANDPIPER (Tringa glareola)

The wood sandpiper (Tringa glareola) is a small wader belonging to the sandpiper family Scolopacidae. A Eurasian species, it is the smallest of the shanks, a genus of mid-sized, long-legged waders that largely inhabit freshwater and wetland environments, as opposed to the maritime or coastal habitats of other, similar species.

The wood sandpiper was formally described in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his Systema Naturae under the current binomial name Tringa glareola. Linnaeus cited his own Fauna Svecica that had been published in 1746. He specified the type locality as Europe but it is now restricted to Sweden. The species is considered to be monotypic: no subspecies are recognised. The genus name, Tringa, is the Neo-Latin name given to the green sandpiper (Tringa ochropus) in 1599 by Aldrovandus, based on the Ancient Greek trungas, a "thrush-sized, white-rumped, tail-bobbing" wading bird mentioned by Aristotle. The specific glareola is from the Latin glarea, meaning "gravel".

The wood sandpiper resembles a longer-legged, more delicate form of the aforementioned green sandpiper (T. ochropus), or a solitary sandpiper (T. solitaria), albeit with a shorter, finer bill, brown back and longer yellowish legs. The wood sandpiper differs from the green by having a smaller, less contrasting white rump-patch, while the solitary sandpiper has no rump-patch, at all. However, the wood sandpiper is not closely related to these two species; its closest relative is the common redshank (T. totanus), with which it shares a sister relationship with the marsh sandpiper (T. stagnatilis). These three species are a group of smallish shanks with red or yellowish legs, displaying a breeding plumage of subdued, light-brown above (with some darker mottling), and a pattern of somewhat smaller, diffuse, brownish spots on the breast and neck.

The wood sandpiper breeds in subarctic wetlands, from the Scottish Highlands in the west, east across Eurasia and the Palearctic. They will migrate to Africa, South Asia (particularly India) and Australia. Vagrant birds have been seen as far into the Pacific as the Hawaiian Islands. In Micronesia, it is a regular visitor to Palau and the Mariana Islands, where flocks of up to 32 birds have been reported; it is observed and recorded on Kwajalein, Marshall Islands, approximately once each decade. The wood sandpiper is also encountered in the Western Pacific region of East Asia and some Western Pacific islands between mid-October and mid-May. A slight westward-expansion saw the establishment of a small resident breeding population in Scotland, beginning in the 1950s. This species is usually found in and around freshwater habitats during migration and wintering.

Mature wood sandpipers moult all of their primary feathers between August and December, whilst juvenile birds shed a varying number of outer primaries between December and April, much closer to their departure from Africa. Immature birds are also much more flexible than older birds regarding the timing (and rate) of their moult and refueling. Adults and immatures which accumulate fuel loads of c.50% of their lean body mass can potentially cross distances of 2397–4490 km in one non-stop flight.

The wood sandpiper nests primarily on the ground, or will re-use an abandoned tree nest of another bird species, such as the fieldfare (Turdus pilaris). Four pale-green eggs are laid between March and May. These are incubated by both sexes beginning with the last egg. They hatch after 22 to 23 days. They are initially cared for by both parents but the female normally departs after a few days. The young can feed themselves. The young fledge when aged around 30 days.

They forage for invertebrates by probing their bills in shallow water or into wet mud, such as lakeshores or riverbanks, and mainly eat aquatic insects, crustaceans, arthropods, various worms, and other small prey.

The wood sandpiper is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) applies. With an apparently stable, healthy global population, it is considered a Species of Least Concern, as per the IUCN.

Arboreal Nesting: While most sandpipers nest exclusively on the ground, the Wood Sandpiper often reuses abandoned tree nests of other birds, such as those of the Fieldfare.

Long-Distance Migration: They are "marathon" flyers, capable of traveling up to 4,490 km (approx. 2,790 miles) in a single non-stop flight after refueling.

Parental Roles: Both parents incubate the typically four pale-green eggs. However, the female often departs just a few days after the chicks hatch to regain energy, leaving the male to raise the young until they can fly at about 30 days old.

Defensive Tactics: When threatened, they may feign injury (pretending to have a broken wing) to lure predators away from their nest.

9-12-2021 CITY OF ARTS AND SCIENCES, VALENCIA - RED CRESTED POCHARD (MALE) (Netta rufina)

The Red-crested Pochard, Netta rufina, is a striking large diving duck. Its name is drawn from the Greek word for duck, 'Netta', and the Latin 'rufina', meaning 'golden-red', a nod to the male's vibrant plumage.

Males are resplendent with a rounded orange head, a red bill, and a contrasting black breast. Their sides are a crisp white, with a brown back and a black tail. Females, on the other hand, are clad in more subdued tones, primarily pale brown with a darker back and crown, and a whitish face. During eclipse, males resemble females but retain their red bills.

These ducks favor lowland marshes and lakes, thriving in the wetland habitats of southern Europe.

The Red-crested Pochard breeds from the steppe and semi-desert regions near the Black Sea to Central Asia and Mongolia. It is a somewhat migratory species, with northern populations wintering in the Indian Subcontinent and Africa.

Gregarious by nature, Red-crested Pochards form large flocks in the winter, often mingling with other diving ducks such as the Common Pochard. They are known to both dive and dabble for their food.

The red-crested pochard (Netta rufina) is a large diving duck. The scientific name is derived from Greek Netta "duck", and Latin rufina, "golden-red" (from rufus, "ruddy"). Its breeding habitat is lowland marshes and lakes in southern Europe and it extends from the steppe and semi-desert areas on the Black Sea to Central Asia and Mongolia, wintering in the Indian subcontinent and Africa. It is somewhat migratory, and northern birds winter further south into north Africa.

The adult male is unmistakable. It has a rounded orange head, red bill and black breast. The flanks are white, the back brown, and the tail black. The female is mainly a pale brown, with a darker back and crown and a whitish face. Eclipse males are like females but with red bills. They are gregarious birds, forming large flocks in winter, often mixed with other diving ducks, such as common pochards. They feed mainly by diving or dabbling. They eat aquatic plants, and typically upend for food more than most diving ducks.

9-12-2021 CITY OF ARTS AND SCIENCES, VALENCIA - COMMON POCHARD (MALE) (Aythya ferina)

The Common Pochard (Aythya ferina) is a medium-sized diving duck, belonging to the family Anatidae. It is a bird of robust build, with a sloping forehead and a relatively long bill. The male is distinguished by its chestnut head and neck, black breast and tail, and pale grey body with fine vermiculations. The female is more subdued in coloration, with a brownish body and a less vibrant head and neck.

Males can be identified by their striking chestnut head and neck, black breast, and pale grey body. They have a dark grey bill with a blue-grey band and yellow-orange to red irises, which intensify during the breeding season. Females and juveniles are less colorful, with brownish tones and grey legs and feet. The female's iris is brown, sometimes with a yellowish tinge, while juveniles have a yellow-olive iris that darkens with age.

Gregarious by nature, Red-crested Pochards form large flocks in the winter, often mingling with other diving ducks such as the Common Pochard. They are known to both dive and dabble for their food.

A wheezing veht call can be given by the male. Series of hoarse vrah-vrah-vrah calls can also be heard from females.

Red-crested pochards build nests by the lakeside among vegetation and lay 8–12 pale green eggs. The birds' status in the British Isles is much confused because there have been many escapes and deliberate releases over the years, as well as natural visitors from the continent. However, it is most likely that they are escapees that are now breeding wild and have built up a successful feral population.

13-12-2021 PEGO MARJAL, ALICANTE - LITTLE EGRET (Egretta garzetta)

https://www.inaturalist.org/taxa/4943-Egretta-garzetta

13-12-2021 PEGO MARJAL, ALICANTE - BOOTED EAGLE (Hieraaetus pennatus)

The Booted eagle (Hieraaetus pennatus) is a small mostly migratory bird of prey with a wide distribution. Despite its small size, the Booted eagle is a fierce hunter that usually captures and kill its prey in its powerful talons.

There are two relatively distinct plumage forms of the Botted eagle. Pale birds are mainly light grey with a darker head and flight feathers. The other form has mid-brown plumage with dark grey flight feathers.

Booted eagles breed in many different regions in both the northern and southern hemisphere. These include southern Europe, North Africa, and across Asia, and also in western South Africa and Namibia. The northern populations are migratory spending November to February in Sub-Saharan Africa and South Asia, while the small southern African populations are sedentary. Booted eagles prefer to live in wooded, often hilly countryside with some open areas. They breed in rocky, broken terrain but migrants may use almost any type of habitat except the dense forest. The birds of the Palearctic breeding population usually nest in coniferous or deciduous woodlands and often in trees.

Booted eagles are active during the day and are typically seen in pairs or as solitary individuals. They fly at relatively low heights, making them conspicuous. Booted eagles typically hunt on the wing, stooping quickly with wings folded in and feet extended. They can also catch insects while walking on the ground. The common call of Booted eagles is a shrill 'kli-kli-kli'.

Booted eagles are monogamous. They form strong pair bonds that last for life. With the start of the breeding season, pairs can be seen circling high above in spectacular display. Egg-laying takes place between March and June. The female lays 1-2 eggs in a nest built from sticks and lined with green leaves in a tree or on a crag, or it takes over the disused nest of another large bird such as a Black kite or Grey heron. The female incubates the egg for around 45 days and is fed by the male during this time. After hatching she guards the nest and the young while the male provides all the food. The chicks fledge after 50-55 days and continue to be fed by both parents for another 2 weeks.

9-12-2021 CITY OF ARTS AND SCIENCES, VALENCIA - LOGGERHEAD SEA TURTLE (Caretta caretta)

https://www.inaturalist.org/taxa/39665-Caretta-caretta

9-12-2021 CITY OF ARTS AND SCIENCES, VALENCIA - YELLOW LEGGED GULL (Larus michahellis)

The Yellow-legged Gull (Larus michahellis) is a large, robust seabird with a commanding presence. Its size can be quite variable, with the smallest females being scarcely larger than a Common Gull, and the largest males approaching the heft of a Great Black-backed Gull. Adults typically exhibit a grey back, a shade lighter than that of the Lesser Black-backed Gull, and their heads are notably whiter in the autumn months. A distinctive feature is their yellow legs, which give this species its common name.

When observing the Yellow-legged Gull, look for the yellow legs that contrast with the grey back and the white head, which becomes even whiter during the autumn. The wing tips are black with limited white spots, and adults have a red spot on the bill. The eye is surrounded by a red ring. Juveniles can be identified by their paler head, rump, and underparts, dark bill and eyes, and a black band on the tail.

This gull favors a variety of coastal environments, often nesting on sea cliffs, islands, and occasionally on buildings within urban settings. It is also known to breed on trees in some regions.

The Yellow-legged Gull has a breeding range centered around the Mediterranean Sea, extending to the Atlantic islands and coasts as far north as Brittany and west to the Azores. Its presence is also noted on the western side of the Black Sea.

The species is known for its adaptability, with many individuals remaining in the same area year-round, while others migrate to milder regions of western Europe or head south to areas such as Senegal and the Red Sea. Post-breeding dispersal can lead to increased numbers in regions like southern England from July to October.

9-12-2021 CITY OF ARTS AND SCIENCES, VALENCIA - HARBOR SEAL (Phoca vitulina)

The harbor (or harbour) seal (Phoca vitulina), also known as the common seal, is a true seal found along temperate and Arctic marine coastlines of the Northern Hemisphere. The most widely distributed species of pinniped (walruses, eared seals, and true seals), they are found in coastal waters of the northern Atlantic and Pacific oceans, Baltic and North seas.

Harbor seals are brown, silvery white, tan, or grey, with distinctive V-shaped nostrils. An adult can attain a length of 1.85 m (6.1 ft) and weigh up to 168 kg (370 lb). Blubber under the seal's skin helps to maintain body temperature. Females outlive males (30–35 years versus 20–25 years). Harbor seals stick to familiar resting spots or haulout sites, generally rocky areas (although ice, sand, and mud may also be used) where they are protected from adverse weather conditions and predation, near a foraging area. 

Males may fight over mates under water and on land. Females bear a single pup after a nine-month gestation, which they care for alone. Pups can weigh up to 16 kg (35 lb) and are able to swim and dive within hours of birth. They develop quickly on their mothers' fat-rich milk, and are weaned after four to six weeks.

The global population of harbor seals is 350,000–500,000, but the freshwater subspecies Ungava seal in Northern Quebec is endangered.[1] Once a common practice, sealing is now illegal in many nations within the animal's range.
