8-6-2019 KHWAI CAMP, BOTSWANA - AFRICAN OPENBILL (Anastomus lamelligerus)

The African Openbill (Anastomus lamelligerus ) is a species of stork from the family Ciconiidae. It is widely distributed in Sub-Saharan Africa and western regions of Madagascar. This species is considered common to locally abundant across its range, although it has a patchy distribution. Some experts consider there to be two sub-species, A. l. lamelligerus distributed on the main continent and A. l. madagascariensis living on the island of Madagascar. Scientists make the difference between the two sub-species due to the more pronounced longitudinal ridges on the bills of adult A. l. madagascariensis.The Asian Openbill (Anastomus oscitans ) distributed in Asia is the African Openbill’s closest relative. The two species share the same notably large bill of a peculiar shape that gives them their name.

The African Openbill is a stork measuring 80-94 cm and weighing 1-1.3 kg. The species does not exhibit any major sexual dimorphism, although the males are slightly larger than the females and have a longer and heavier bill. The adult bill is between 135-196 mm in length, brownish in color and has a gap between the upper and lower mandible. This gap is non-existent in juvenile birds and develops as the bird ages. It is because the two mandibles of the beak only meet at the tip and not in the middle that this stork genus received the name of “openbill”.

The adult plumage is overall black with iridescent green feathers on their backs, coverts and abdomens. The juvenile plumage is usually less vibrant and browner in color with the feathers of the underparts having pale tips. The legs and feet are black. The eyes are grey with grey lores and no distinct coloration of the eye-ring.

These storks are smaller in stature than most of the other species in their family which allows them to be much more agile in the air. This agility can be observed during their descents from high altitudes as they often perform steep dives and remarkable acrobatic manoeuvres. During their migration flights, the African openbill storks will use sustained flapping flight with an average wing flap rate of 200-210 flaps/minute. They will also often soar on the thermals when commuting to and from distant feeding areas. This allows them to travel long distances to obtain food without expending too much energy. In flight, these birds have their necks and head extended and their long, broad wings are spread out and perfect for soaring and gliding on the air currents.

Some African Openbill population are trans-equatorial migrants. Timing their migration to arrive in West Africa for the start of the dry period. They migrate in flocks and most of the reason and organisation behind these movements remain unknown. Some populations migrate while others are residents, migration in African Openbill highly depends on the weather conditions.

7-6-2019 MOREMI CAMP, BOTSWANA - YELLOW BILLED STORK (Mycteria ibis)

The Yellow-billed Stork, Mycteria ibis, is a striking wader of the African continent. This medium-sized stork, with a height ranging from 90 to 105 cm, is adorned with a predominantly white plumage contrasted by a short black tail with a green and purple sheen. Its namesake yellow bill is slightly curved at the end, distinguishing it from other storks.

During the breeding season, the Yellow-billed Stork's plumage is tinged pink on the upperwings and back, and its legs turn a vivid pink. The male is generally larger with a longer bill compared to the female. Juveniles can be identified by their greyish-brown coloration, dull yellowish bill, and brown legs.

This species favors wetlands, shallow lakes, and mudflats, typically in water depths of 10-40 cm, avoiding heavily forested areas and deep waters unsuitable for their feeding techniques.

The Yellow-billed Stork is found across Eastern Africa, from Senegal and Somalia to South Africa, and in parts of Madagascar. It exhibits local migratory movements influenced by rainfall patterns.

These storks are known for their high-stepped stalking gait and impressive flight aerobatics. They are generally non-vocal but may emit hissing screams during social displays in the breeding season.

The species is mostly silent, but during the breeding season, it engages in bill clattering and a distinctive "woofing" wing beat. Nestlings produce a loud, monotonous braying call to solicit food from adults.

7-6-2019 MOREMI CAMP, BOTSWANA - YELLOW BILLED DUCK (Anas undulata)

The yellow-billed duck (Anas undulata ) is a 51–58 cm long dabbling duck which is an abundant resident breeder in southern and eastern Africa. This duck is not migratory, but wanders in the dry season to find suitable waters. It is highly gregarious outside the breeding season and forms large flocks.

These are mallard-sized mainly grey ducks with a darker head and bright yellow bill. The wings are whitish below, and from above show a white-bordered green speculum. Sexes are similar, and juveniles are slightly duller than adults. The north-eastern race is darker and has a brighter bill and blue speculum.

It is a bird of freshwater habitats in fairly open country and feeds by dabbling for plant food mainly in the evening or at night. It nests on the ground in dense vegetation near water. Rarely, it is found in suburban areas, in close proximity to golf courses, parks and lakes or dams. The clutch numbers between six and twelve eggs.

The male has a teal-like whistle, whereas the female has a mallard-like quack.

There are two subspecies of the yellow-billed duck: A. undulata rueppelli (northern yellow-billed duck) and A. undulata undulata (southern yellow-billed duck). The yellow-billed duck is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) applies. The southern nominate subspecies is declining due to competition and hybridization with feral mallards (Rhymer 2006).

The male yellow-billed duck performs multiple displays of courtship, similar to many other African ducks. The number of courtship displays the yellow-billed ducks perform is greater than many other African ducks. Ornithologists have noted seven majorate displays of courtship. 

7-6-2019 MOREMI CAMP, BOTSWANA - COMMON TSESSEBE (Damaliscus lunatus ssp. lunatus)

The common tsessebe or sassaby (Damaliscus lunatus lunatus) is the southern, nominate subspecies of Damaliscus lunatus, although some authorities have recognised it as an independent species. It is most closely related to the Bangweulu tsessebe, sometimes also seen as a separate species, less to the topi, korrigum, coastal topi and tiang subspecies of D. lunatus, and less to the bontebok in the same genus. Common tsessebe are found in Angola, Zambia, Namibia, Botswana, Zimbabwe, Eswatini (formerly Swaziland), and South Africa. 

Common tsessebe are among the fastest antelopes in Africa and can run at speeds up to 90 km/h.

Adult tsessebe are 150 to 230 cm in length.[7] They are quite large animals, with males weighing 137 kg and females weighing 120 kg, on average. Their horns range from 37 cm for females to 40 cm for males. For males, horn size plays an important role in territory defense and mate attraction, although horn size is not positively correlated with territorial factors of mate selection. Their bodies are chestnut brown. The fronts of their faces and their tail tufts are black; the forelimbs and thighs are greyish or bluish-black. Their hindlimbs are brownish-yellow to yellow and their bellies are white. In the wild, tsessebe usually live a maximum of 15 years, but in some areas, their average lifespan is drastically decreased due to overhunting and the destruction of habitat.

The most significant difference between the tsessebe, the southernmost subspecies, and the other topi subspecies is the incline of the horns, with the tsessebe having horns which are placed further apart from each other as one moves distally. This has the effect of the space between them having a more lunate profile when seen from a certain angle, as opposed to lyrate, more like that of a hartebeest. Tsessebe populations show variation as one moves from South Africa to Botswana, with southerly populations having on average the lightest pelage colour, smallest size and the least robust horns. Common tsessebe do not differ significantly from the Bangweulu tsessebe, the northernmost population, but in general the populations from that part of Zambia are on average the darkest-coloured and have the most robust horns, although differences are slight and individuals in both populations show variation in these characteristics which almost completely overlap each other.

Tsessebe are social animals. Females form herds composed of six to 10, with their young. After males turn one year of age, they are ejected from the herd and form bachelor herds that can be as large as 30 young bulls. Territorial adult bulls form herds the same size as young bulls, although the formation of adult bull herds is mainly seen in the formation of a lek. Tsessebe declare their territory through a variety of behaviors. Territorial behavior includes moving in an erect posture, high-stepping, defecating in a crouch stance, ground-horning, mud packing, shoulder-wiping, and grunting.

The most important aggressive display of territorial dominance is in the horning of the ground. Another far more curious form of territory marking is through the anointing of their foreheads and horns with secretions from glands near their eyes. Tsessebe accomplish this by inserting grass stems into their preorbital glands to coat them with secretion, then waving it around, letting the secretions fall onto their heads and horns. This process is not as commonly seen as ground-horning, nor is its purpose as well known.

7-6-2019 MOREMI CAMP, BOTSWANA - SWAINSON'S SPURFOWL (Pternistis swainsonii)

Swainson's spurfowl, also known as Swainson's francolin, is a bird that belongs to the family Phasianidae. It is a native species to the southern regions of Africa. The bird is named in honor of William Swainson, a notable English ornithologist.

A large brown francolin with some darker streaks, dark blackish legs, and a distinctive bare red face and throat. It frequents grasslands and savannas where it is bold and conspicuous, standing on open branches and termite mounds to call its loud screeching “kreeeeet-kreeeeet-kreeeet” call at dawn and dusk. Red-necked Francolin differs by having red legs and feet, by often having white plumage on the underparts or face (depending on the race), and by preferring thickets and forest to open habitats.

The Swainson's spurfowl is found in a variety of habitats, ranging from grasslands to woodlands. These environments provide the necessary cover and food sources for the species.

This bird has a wide range across southern Africa, with sightings confirmed in Angola, Botswana, Lesotho, Malawi, Mozambique, Namibia, South Africa, Eswatini, Zambia, and Zimbabwe.

Information on the breeding habits of Swainson's spurfowl includes observations of hatchlings and juveniles in locations such as Kruger National Park and Zambia, indicating active reproduction in these areas.

As with many birds in the Phasianidae family, Swainson's spurfowl have a diet that includes a variety of seeds, insects, and possibly other small invertebrates.

The IUCN Red List has classified Swainson's spurfowl as Least Concern, indicating that, at present, the species does not face any immediate threat of extinction.

7-6-2019 MOREMI CAMP, BOTSWANA - SAVANNAH ELEPHANT (JUVENILE) (Loxodonta Africana)

The African bush elephant (Loxodonta africana), also known as the African savanna elephant, is a species of elephant native to sub-Saharan Africa. It is one of three extant elephant species and, along with the African forest elephant, one of two extant species of African elephant. It is the largest living terrestrial animal, with fully grown bulls reaching an average shoulder height of 3.04–3.36 metres (10.0–11.0 ft) and a body mass of 5.2–6.9 tonnes (5.7–7.6 short tons); the largest recorded specimen had a shoulder height of 3.96 metres (13.0 ft) and an estimated body mass of 10.4 tonnes (11.5 short tons). The African bush elephant is characterised by its long prehensile trunk with two finger-like processes; a convex back; large ears which help reduce body heat; and sturdy tusks that are noticeably curved. The skin is grey with scanty hairs, and bending cracks which support thermoregulation by retaining water.

The African bush elephant (Loxodonta africana), also known as the African savanna elephant, is a species of elephant native to sub-Saharan Africa. It is one of three extant elephant species and, along with the African forest elephant, one of two extant species of African elephant. It is the largest living terrestrial animal, with fully grown bulls reaching an average shoulder height of 3.04–3.36 metres (10.0–11.0 ft) and a body mass of 5.2–6.9 tonnes (5.7–7.6 short tons); the largest recorded specimen had a shoulder height of 3.96 metres (13.0 ft) and an estimated body mass of 10.4 tonnes (11.5 short tons). The African bush elephant is characterised by its long prehensile trunk with two finger-like processes; a convex back; large ears which help reduce body heat; and sturdy tusks that are noticeably curved. The skin is grey with scanty hairs, and bending cracks which support thermoregulation by retaining water.

The African bush elephant inhabits a variety of habitats such as forests, grasslands, woodlands, wetlands and agricultural land. It is a mixed herbivore feeding mostly on grasses, creepers, herbs, leaves, and bark. The average adult consumes about 150 kg (330 lb) of vegetation and 230 L (51 imp gal; 61 US gal) of water each day. A social animal, the African bush elephant often travels in herds composed of cows and their offspring. Adult bulls usually live alone or in small bachelor groups. During the mating season, males go through a process called musth, a period of high testosterone levels and heightened aggression. For females, the menstrual cycle lasts three to four months, and gestation around 22 months, the longest of any mammal.

Since 2021, the African bush elephant has been listed as Endangered on the IUCN Red List. It is threatened foremost by habitat destruction, and in parts of its range also by poaching for meat and ivory. Between 2003 and 2015, the illegal killing of 14,606 African bush elephants was reported by rangers across 29 range countries. Chad is a major transit country for smuggling of ivory in West Africa. This trend was curtailed by raising penalties for poaching and improving law enforcement. Poaching of the elephant has dated back to the 1970s and 80s, which were considered the largest killings in history. In human culture, elephants have been extensively featured in literature, folklore and media, and are most valued for their large tusks in many places.

20-6-2019 CAMI LES FONTS OLIVA, VALENCIA - MALLARD (JUVENILE) (Anas platyrhynchos)

Mallards are adaptable, medium-sized ducks found in wetlands across the Northern Hemisphere. Males have a distinctive green head and white neck ring, while females are mottled brown, but both share a purplish-blue wing patch called a speculum. They are omnivorous, eating a wide range of foods like seeds, aquatic plants, and insects, and most mallards are migratory, with ducklings able to swim and forage shortly after hatching. 

Appearance and identification

Male (Drake): Glossy green head, white neck collar, and a reddish-brown chest.

Female (Hen): Mottled brown plumage for camouflage.

Both sexes: Have a purple-blue speculum (wing patch) with white borders.

Other features: Yellow or orange bills and feet.

Diet and behavior

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

Foraging: They are dabbling ducks, meaning they skim the water's surface to feed, especially in shallow water.

Social: They are highly social and often form large flocks.

Vocalization: Females produce the loud "quack" sound, while males make a lower-pitched call. 

Reproduction and lifecycle

Pairing: Form pairs in the fall and winter.

Nesting: Females build a nest in a depression on the ground, lining it with grasses and down.

Eggs: Lay between 5 and 15 eggs, which she incubates for 26 to 30 days.

Ducklings: Can run, swim, and forage within a day of hatching.

Lifespan: Average lifespan is around 3-5 years, but some can live much longer, with the oldest known mallard reaching 27 years. 

20-6-2019 OLIVA MARJAL, VALENCIA - RED EARED SLIDER TERRAPIN (Trachemys scripta ssp. elegans)

20-6-2019 CAMI LES FONTS OLIVA, VALENCIA - EURASIAN BLACKBIRD (MALE) (Turdus merula)

The Common Blackbird thrives in a variety of habitats including woodlands with dense undergrowth, gardens, parks, and hedgerows. It shows a preference for deciduous trees and areas with thick vegetation.

This species is widespread across Europe, western Asia, and North Africa. It has also been introduced to Australia and New Zealand. Its range varies from resident populations in the milder regions to partially or fully migratory populations in areas with more severe winters.

The Common Blackbird is territorial, especially during breeding season, with males displaying distinctive threat behaviors to ward off rivals. Outside of breeding season, they can be more sociable, often forming small flocks. The species is known for its adaptability to urban environments, where it may overwinter more readily than in rural settings.

The male's song is a melodious and fluted warble, often heard from elevated perches during the breeding season. The Common Blackbird also has a repertoire of calls including a sharp "seee" when agitated and a "pook-pook-pook" to signal ground predators.

7-6-2019 MOREMI CAMP, BOTSWANA - SOUTHERN RED BILLED HORNBILL (Tockus rufirostris)

The southern red-billed hornbill (Tockus rufirostris) is a species of hornbill in the family Bucerotidae, which is native to the savannas and dryer bushlands of southern Africa. It is replaced by a near-relative, the Damara red-billed hornbill, in the arid woodlands of western Namibia. All five red-billed hornbills were formerly considered conspecific.

The sexes are similar, but males are larger and heavier. Males also have somewhat longer bills, with the lower mandible coloured black to a variable extent. It is distinguishable from other red-billed hornbills by the combination of yellow iris and pale orbital skin (pink to greyish), and the ample blackish plumage streaking from the ear coverts to the side of the neck. The throat is white, and the wing coverts clearly spotted.

The call consists of an accelerating series notes, kuk kuk kuk ... which ends in a crescendo of double notes, kuk-we kuk-we. Unlike other red-billed hornbills, Southern red-billed hornbills do not raise their wings in display.

It is found from Malawi and Zambia to southern Angola, northeastern Namibia, Botswana, Zimbabwe, eastern Eswatini and northern South Africa (Transvaal and northern KZN province). It occurs in the upper Zambezi valley of Mozambique, but is mostly absent from the eastern lowlands.

20-6-2019 RACO DE OLLA, VALENCIA - LITTLE CRAKE (Zapornia parva)

The Little Crake, Zapornia parva, is a diminutive member of the Rallidae family, whose Latin name aptly translates to "small". This species exhibits a striking sexual dimorphism, with males and females donning distinct plumage.

Adult males of the Little Crake are characterized by brown upperparts and a blue-grey face and underparts. The bill is short and straight, yellow with a red base, and the legs are green with elongated toes. The tail is short, displaying a black and white barred pattern underneath. Females, on the other hand, have buff underparts and are grey only on the face. Immature birds resemble females but have a white face and breast. The downy chicks are uniformly black, a common trait among rails.

The preferred breeding habitat of the Little Crake is reed beds, where they find shelter and nesting sites.

These birds are indigenous to Europe, predominantly in the eastern regions, and extend their range just into western Asia. They are migratory, retreating to Africa to overwinter.

Little Crakes are elusive during the breeding season, often heard rather than seen. They become more visible during migration and are known for their yapping "kua" call.

 

The vocalizations of the Little Crake include a distinctive yapping call, which can be more frequently heard during their migratory period.

Nesting in dry spots amidst reed vegetation, the Little Crake lays a clutch of 4–7 eggs. Their secretive nature is most pronounced during this time.

The Little Crake can be readily distinguished from the Spotted Crake by the absence of dark barring and white spots on the flanks. It is also similar in appearance to the Baillon's Crake, which is slightly smaller and has strongly barred flanks, and the Yellow-breasted Crake of the American tropics.

Their diet consists mainly of insects and aquatic animals, which they forage for by probing in mud or shallow water and by sight.

The Little Crake is classified as Least Concern on the IUCN Red List, and it is one of the species protected under the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA).

19-6-2019 RACO DE OLLA, VALENCIA - BLACK WINGED STILT (FEMALE) (Himantopus himantopus)

Striking large black-and-white wader with a thin, straight bill and bright pink legs, found in wetlands with open shallow water throughout much of Africa and Eurasia, often in brackish habitats. Some populations are migratory, departing northerly breeding grounds for warmer southern regions. Often forms noisy colonies on bare ground near water. Essentially unmistakable throughout much of its range, but compare with Pied Stilt in parts of Southeast Asia. Feeds by wading in water, picking from the water surface with its needle-like bill. In flight, long pink legs stick out far beyond the tail. Calls loudly and stridently, especially when alarmed during the breeding season.

The black-winged stilt (Himantopus himantopus) is a widely distributed, very long-legged wader in the avocet and stilt family Recurvirostridae. Its scientific name, Himantopus himantopus, is sometimes used to generalize a single, almost cosmopolitan species. Alternatively, it is restricted to the form that is widespread in Europe, Asia and Africa, which equals the nominate group of H. himantopus sensu lato. Meanwhile, the black-necked (H. mexicanus) and white-backed stilts (H. melanurus) both inhabit the Americas; the pied stilt (H. leucocephalus) ranges from Australasia and New Zealand. Today, most sources accept between one and four actual species. The taxonomic name Himantopus comes from Greek, meaning "strap-foot" or "thong-foot".

Adults are 33–36 cm (13–14 in) long, with long, pink legs, and a long, rather thin black bill. The birds are generally black above and white below, with a white head and neck (with a varying amount of black, species-dependent). Males have a black back, often with a greenish gloss or sheen. Females' backs have a brownish hue, contrasting with the black remiges. In populations where the top of the head is normally white (at least in winter), females tend to have less black on the head and neck the entire year-round, while males often have much more black, particularly in summer. This difference is not clear-cut, however, and males usually grow all-white head feathers in winter. 

Immature birds are grey, instead of black, and have a markedly sandy hue on their wings, with light feather fringes appearing as a whitish line in flight.

19-6-2019 RACO DE OLLA, VALENCIA - BLACK WINGED STILT (Himantopus himantopus)

The Black-winged Stilt, Himantopus himantopus, is a slender wader known for its strikingly long, pink legs and contrasting black-and-white plumage. This elegant bird is a member of the avocet and stilt family, Recurvirostridae.

Adult Black-winged Stilts measure 33–36 cm in length. They possess a long, thin black bill and display a distinctive black and white coloration. The head and neck are predominantly white, with variable black markings depending on the sex and subspecies. Males typically have a glossy or greenish sheen on their black backs, while females exhibit a more brownish tinge. During flight, their long legs trail behind, and their wingbeats are steady.

These birds favor marshes, shallow lakes, and ponds as their breeding grounds. They are also known to inhabit coastal areas during migration and in the winter months.

The Black-winged Stilt has a wide range, extending across Europe, Asia, and Africa. Some populations migrate to coastal regions in winter, while others in milder climates may remain resident or engage in short-range movements.

Black-winged Stilts are often seen foraging in shallow waters, gracefully picking insects and crustaceans from the surface. They are known to nest in small groups, sometimes alongside avocets, and exhibit a variety of courtship behaviors, including intricate displays and duets.

The flight call of the Black-winged Stilt is a sharp and clear kleek, typically heard during its aerial maneuvers.

Nests are simple bare spots on the ground near water. These birds are communal nesters and may breed in loose colonies. They have been known to breed as far north as Britain, with recent successful breeding events recorded in Southern and Northern England.

The Black-winged Stilt can be confused with other stilt species, such as the Black-necked Stilt (H. mexicanus) in the Americas, the White-backed Stilt (H. melanurus), and the Pied Stilt (H. leucocephalus) in Australasia and New Zealand.

Their diet consists mainly of insects and crustaceans, which they deftly pick from the water's surface or from wet sand.

The IUCN lists the Black-winged Stilt as Least Concern, indicating a stable global population. However, they are protected under the Agreement on the Conservation of African-Eurasian Migratory Waterbirds, highlighting the importance of international cooperation in their conservation.

19-6-2019 RACO DE OLLA, VALENCIA - BLACK TAILED SKIMMER DRAGONFLY (Orthetrum cancellatum)

The black-tailed skimmer (Orthetrum cancellatum) is a dragonfly belonging to the family Libellulidae.

This species is widespread in Europe and Asia. It is found throughout European continent including the Mediterranean islands but is absent in the north of Britain and the northern half of Fennoscandia. This is one of the most common European species and it is still increasing its range northwards. To the east, the range extends over central Asia to Kashmir, Mongolia to the northern parts of China and Arunachal Pradesh in India.

It is present in Albania, Austria, Azerbaijan, Belarus, Belgium, Bosnia and Herzegovina, Bulgaria, China, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France (Corsica, and mainland), Georgia, Germany, Greece, Hungary, India, Ireland, Italy, Kazakhstan, Kyrgyzstan, Latvia, Lithuania, Luxembourg, Malta, Moldova, Mongolia, Montenegro, Netherlands, North Macedonia, Norway, Poland, Portugal, Romania, Russia, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Tajikistan, Turkey (Turkey-in-Europe), Turkmenistan, Ukraine, Uzbekistan and in part of United Kingdom.

The black-tailed skimmer is abundant throughout its range and is one of the most commonly seen dragonflies in Europe. It holds a stable population and has no known major threats.

This species has expanded its range, assisted by the creation of gravel pits which give it the extensive open unvegetated areas it prefers. It was first recorded in Great Britain in Essex in 1934. It is decreasing rapidly in the Maltese Islands.

This dragonfly is found at any open water with bare patches along the shore where the patrolling males frequently rest in the sun. It also inhabits near slow-flowing waters. It favors lakes, slow rivers, ponds and sometimes marshy area, without dense riparian vegetation. Females are less bold and not encountered as regularly. Adults prefer to perch on bare ground and rocks.

19-6-2019 RACO DE OLLA, 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.

Common Terns are agile flyers, capable of rapid turns, hovering, and vertical take-off. They are known for their powerful, direct flight and can fly at speeds averaging 30 km/h, increasing during migration. They breed in colonies, often alongside other seabird species, and exhibit strong territorial behavior.

The Common Tern has a distinctive alarm call, a KEE-yah, and a repertoire of other vocalizations used for communication within the colony and with their chicks. Parents and chicks recognize each other's calls, aiding in maintaining family bonds.

Breeding involves aerial courtship displays and ground rituals. Nests are shallow scrapes, sometimes lined with debris. Clutch size is typically three eggs, camouflaged with blotchy patterns. Both sexes incubate, and chicks fledge in 22–28 days. Adults are defensive of their nest and young, often harassing intruders.

The Common Tern can be confused with the Arctic Tern, Roseate Tern, and Forster's Tern, but differences in plumage details, leg and bill color, and vocalizations aid in distinguishing them.

The diet consists mainly of fish, which they catch by plunge-diving, but may also include molluscs, crustaceans, and large insects. They forage up to 15 km from the breeding colony and may follow schools of fish or predatory fish to locate prey.

The Common Tern is classified as Least Concern, with a large population and extensive breeding range. However, threats such as habitat loss, pollution, and disturbance have led to declines in some areas, particularly in North America. Conservation efforts include habitat management and protection from human disturbance.

The Black-winged Stilt can be confused with other stilt species, such as the Black-necked Stilt (H. mexicanus) in the Americas, the White-backed Stilt (H. melanurus), and the Pied Stilt (H. leucocephalus) in Australasia and New Zealand.

Their diet consists mainly of insects and crustaceans, which they deftly pick from the water's surface or from wet sand.

The IUCN lists the Black-winged Stilt as Least Concern, indicating a stable global population. However, they are protected under the Agreement on the Conservation of African-Eurasian Migratory Waterbirds, highlighting the importance of international cooperation in their conservation.

19-6-2019 ALBUFERA, VALENCIA - AUDOUIN'S GULL (Ichthyaetus audouinii)

The Audouin's gull, Ichthyaetus audouinii, presents itself as a large gull species, predominantly inhabiting the Mediterranean, the western coast of Saharan Africa, and the Iberian Peninsula. Its name pays homage to the French naturalist Jean Victoire Audouin. Resembling a small European herring gull, the adult Audouin's gull is distinguished by its short, stubby red bill and the unique "string of pearls" white wing primary tips. The legs of this bird are a subtle grey-green, and it takes a full four years for the gull to don its adult plumage.

When observing the Audouin's gull, one should note the red bill and the distinctive pattern of white spots along the wingtips, which contrast with the larger "mirrors" seen in other gull species. These features are key to distinguishing it from its relatives.

This gull favors coastal and pelagic environments, strictly adhering to regions where it can pursue its specialized diet.

The Audouin's gull is found in the Mediterranean, along the western Saharan African coast, and on the Iberian Peninsula. It breeds on small islands, either colonially or in solitude.

Once considered one of the world's rarest gulls, the Audouin's gull has established new colonies but remains a rare sight with a population of around 10,000 pairs. This bird is not known to wander far from its breeding grounds, though occasional records exist of it appearing as far afield as the Netherlands, England, and even Trinidad.
