25-3-2018 TABLE MOUNTAIN AVIARY, CAPE TOWN - WOOD DUCK (MALE) (Aix sponsa)

The Wood Duck, known scientifically as Aix sponsa, is a medium-sized perching duck native to North America. It is one of the most splendidly plumaged waterfowl on the continent. Adult Wood Ducks measure from 47 to 54 cm in length with a wingspan of 66 to 73 cm, and weigh between 454 and 862 grams. The male is particularly striking with iridescent plumage and red eyes, complemented by a distinctive white flare down the neck. The female is more subdued in coloration, featuring a white eye-ring and a whitish throat. Both sexes boast crested heads, and their speculum is an iridescent blue-green with a white trailing edge.

To identify the male Wood Duck, look for its multicolored iridescent plumage and red eyes, along with the white flare down its neck. The female can be recognized by her white eye-ring and whitish throat. Both sexes have crested heads, which are a key feature for identification.

Wood Ducks inhabit wooded swamps, shallow lakes, marshes, ponds, and creeks. They show a preference for areas with ample tree cover close to water bodies.

These ducks are found throughout the eastern United States, the west coast, parts of southern Canada, and the west coast of Mexico. Northern populations migrate south for the winter, while birds in the southern range tend to be year-round residents.

Wood Ducks are known for nesting in tree cavities near water and can produce two broods in a single season in southern regions. They may compete with other species for nesting sites and are known to practice "nest dumping" when nest boxes are placed too closely. The ducklings are precocial and capable of swimming and finding food shortly after hatching.

The male Wood Duck emits a rising whistle, "jeeeeee," while the female makes a drawn-out, rising squeal, "do weep do weep," when flushed, and a sharp "cr-r-ek, cr-e-ek" as an alarm call.

Females typically lay seven to fifteen eggs, which incubate for around thirty days. They line their nests with feathers and other soft materials, and the elevation of the nest provides some protection from predators.

Wood Ducks are omnivores, feeding by dabbling or grazing on land. Their diet consists mainly of berries, acorns, seeds, and insects. They possess the ability to crush acorns in their gizzard after swallowing.

The Wood Duck is currently listed as Least Concern. Conservation efforts, including the establishment of the Migratory Bird Treaty Act and the erection of nesting boxes, have helped their populations rebound from historical declines. They are now the second most commonly hunted duck in North America, after the mallard.

25-3-2018 TABLE MOUNTAIN AVIARY, CAPE TOWN - MANDARIN DUCK (MALE) (Aix galericulata)

The Mandarin Duck (Aix galericulata) is a captivating species of perching duck native to the East Palearctic. Exhibiting pronounced sexual dimorphism, the male is adorned with an array of spectacular colors and ornate plumage, while the female maintains a more subdued appearance. This medium-sized duck measures 41–49 cm in length with a wingspan of 65–75 cm. It shares its genus with the North American Wood Duck, its closest relative.

The male Mandarin Duck is unmistakable with its red bill, large white crescent above the eye, and a face graced with reddish "whiskers." The breast is a rich purple with two vertical white bars, and the flanks are a vibrant ruddy color, complemented by two sail-like orange feathers at the back. The female, on the other hand, resembles the female Wood Duck, with a more muted grayish-lavender plumage, a distinctive white eye-ring, and a stripe extending from the eye. Both sexes boast crests, though the male's is more prominent.

Mandarin Ducks favor the dense, shrubby forested edges of rivers and lakes for breeding. They are typically found in low-lying areas but may also breed in valleys up to 1,500 meters in altitude. In winter, they can be found in marshes, flooded fields, and open rivers, and may also inhabit coastal lagoons and estuaries.

Originally widespread in East Asia, the Mandarin Duck's populations have declined in eastern Russia and China. However, Japan still hosts approximately 5,000 pairs. The species migrates to overwinter in lowland eastern China and southern Japan. In the British Isles and Western Europe, introduced populations have established, with notable numbers in Great Britain and the region of Berlin. Isolated populations also exist in the United States.

Mandarin Ducks are known for their shyness, often seeking cover under trees and forming smaller flocks. They may become more confident in the presence of humans.

Mandarin Ducks breed in densely wooded areas near water sources. They nest in tree cavities, laying a clutch of nine to twelve eggs in the spring. The male does not incubate the eggs and departs before they hatch. The ducklings leap from the nest to follow their mother to water shortly after hatching.

The diet of Mandarin Ducks varies seasonally, consisting mainly of plants and seeds, such as beech mast. They also consume snails, insects, small fish, and in different seasons, acorns, grains, dew worms, frogs, mollusks, and small snakes. They typically feed at dawn or dusk.

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.

1-7-2018 CAMPO DE ARROZ FAVARA, 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.

11-7-2018 BROSQUIL, VALENCIA - EUROPEAN RABBIT (Oryctolagus cuniculus)

The European rabbit (Oryctolagus cuniculus) is a small mammal native to southwestern Europe and northwest Africa. It is known as an invasive species because it has been introduced to countries on all continents with the exception of Antarctica, and has caused many problems within the environment and ecosystems.

The European rabbit is smaller than the European hare and Mountain hare and lacks black ear tips, as well as having proportionately shorter legs. The fur of the European rabbit is generally greyish-brown, but this is subject to much variation. The guard hairs are banded brown and black, or grey, while the nape of the neck and scrotum are reddish. The chest patch is brown, while the rest of the underparts are white or grey. A white star shape is often present on kits' foreheads but rarely occurs in adults. The whiskers are long and black, and the feet are fully furred and buff-coloured. The tail has a white underside, which becomes prominent when escaping danger. This may act as a signal for other rabbits to run. Moulting occurs once a year, beginning in March on the face and spreading over the back. The underfur is completely replaced by October-November. The European rabbit exhibits great variation in colour, from light sandy to dark grey and completely black. Such variation depends largely on the amount of guard hairs relative to regular pelage.

1-7-2018 CAMPO DE ARROZ FAVARA, 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.

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.

The Squacco Heron uses freshwater localities throughout Europe and the Middle East as breeding grounds to later migrate south to the Sub-Saharan African region. Non-breeding Squacco Herons share similar traits with other heron species like the Indian Pond Heron and Malagasy Pond Heron which show tawny color plumage, lighter streaking, smaller bill, and narrower wing tips.

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.

1-7-2018 CAMPO DE ARROZ FAVARA, VALENCIA - GREY HERON (Ardea cinerea)

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

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

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

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

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

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

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

The Grey Heron can be confused with the larger North American Great Blue Heron or the South American Cocoi Heron. However, it can be distinguished by its size and the coloration of its flanks and thighs.

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

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

1-7-2018 CAMPO DE ARROZ FAVARA, VALENCIA - 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.

Known for their ambush hunting tactics, these herons stand motionless at the water's edge, striking at prey primarily during the night or early morning. They exhibit a diverse diet, consuming fish, amphibians, insects, and more. They are also one of the few heron species to use tools, such as bait, to fish. By day, they rest in trees or shrubbery, and outside of breeding season, some subspecies display more sociable tendencies.

The Black-crowned Night Heron is a vocal species within its colonies, often heard making a "quok" or "woc" sound.

Colonial nesters, they construct platforms of sticks in trees or on the ground in protected areas. Clutch sizes range from three to eight eggs.

The Black-crowned Night Heron can be confused with other heron species, but its distinctive black crown, back, and shorter stature help differentiate it.

Their diet is varied, including small fish, crustaceans, insects, small mammals, and even refuse. They have been observed using bait to attract fish, a rare behavior for birds.

The IUCN lists the Black-crowned Night Heron as Least Concern, indicating a stable population across its extensive range.

25-3-2018 TABLE MOUNTAIN AVIARY, CAPE TOWN - RED WINGED STARLING (Onychognathus morio)

The red-winged starling is territorial, aggressive and intolerant when nesting, and will attack other species, including domestic animals and humans. When not breeding, red-winged starlings are highly gregarious and will associate with other members of their species in large flocks.

This starling is a cliff nester, breeding on rocky cliffs, outcrops and gorges. The red-winged starling builds a lined nest of grass and twigs, and with a mud base, on a natural or structural ledge. It lays two to four, usually three, blue eggs, spotted with red-brown. The female incubates the eggs for 13–14 days, with another 22–28 days to fledge. This starling is commonly double-brooded. It may be parasitised by the great spotted cuckoo.

It is preyed upon by other birds such as peregrine falcons, lanner falcons, tawny eagles, cape eagle-owls, pied crows, and gymnogene.

25-3-2018 TABLE MOUNTAIN AVIARY, CAPE TOWN - HAUTLAUB'S GULL (Chroicocephalus hartlaubii)

The Hartlaub's gull (Chroicocephalus hartlaubii), also colloquially known as the king gull, is a small, nimble seabird with a length of 36–38 cm. Its plumage is predominantly white, complemented by a grey back and upperwings. The wingtips are black, adorned with striking white "mirrors." A notable feature is its dark red bill and legs. During the breeding season, it sports a very faint lavender grey hood, while outside of this period, its head remains plain white. Both sexes exhibit similar markings. The Hartlaub's gull is distinguishable from the slightly larger grey-headed gull by its thinner, darker bill, deeper red legs, paler head, and dark eyes. It reaches full maturity in two years, and juveniles can be identified by a brown band across the wings, lacking a black terminal tail band and presenting less dark areas in the wings compared to their grey-headed counterparts.

When observing Hartlaub's gulls, look for the combination of their dark red bill and legs, the white "mirrors" on the black wingtips, and the faint grey hood during breeding season. Juveniles will have a brown band on the wings and darker legs, with a white head that distinguishes them from similar-aged grey-headed gulls.

Hartlaub's gull is a coastal species, favoring the shores and estuaries rather than the open ocean. It is not considered pelagic and is seldom seen far from land.

This gull is a non-migratory breeding resident endemic to the Atlantic coastline of South Africa and Namibia. A significant portion of its population, estimated at around 30,000 birds, resides within the Greater Cape Town area.

Hartlaub's gull is highly social and gregarious, especially in winter. It is known for its raucous, crow-like kaaarrh call, which can be quite loud, particularly in urban colonies. The species has adapted well to human presence and can become very tame around human habitations. Despite being relatively rare globally, it is common within its range and is often considered a nuisance in cities due to its fouling of buildings and noisy nature.

25-3-2018 TABLE MOUNTAIN AVIARY, CAPE TOWN - GREAT WHITE PELICAN (Pelecanus onocrotalus)

The great white pelican, known scientifically as Pelecanus onocrotalus, is a gargantuan bird, surpassed in size only by its cousin, the Dalmatian pelican. With a body length ranging from 140 to 180 cm and a wingspan stretching from 226 to 360 cm, it is one of the largest flying birds. The pelican's bill is an impressive 28.9 to 47.1 cm long, colored in hues of pink and yellow, and is accompanied by a pale-yellow gular pouch. Males are generally larger than females and exhibit a pronounced sexual dimorphism, with males averaging more than 30% heavier than females.

Adult great white pelicans are predominantly white with black flight feathers and a faint pink tinge on the neck. The bill is bluish-grey with a red tip and a yellowish gular pouch. During the breeding season, males display pinkish facial skin, while females exhibit a more orangey hue. Juveniles are distinguishable by their darker, brownish underparts and patterned underwings.

These pelicans favor shallow, warm freshwater environments, such as lakes, swamps, and lagoons, often with dense reed beds nearby for nesting. They are also found in coastal estuarine areas and occasionally at elevations up to 1,372 m in East Africa and Nepal.

The great white pelican breeds from southeastern Europe through Asia to Africa. It is a migratory species with populations found from Eastern Europe to Kazakhstan during the breeding season. In Africa, it is resident south of the Sahara Desert.

The great white pelican is a highly sociable bird, often forming large flocks. It is an adept swimmer and an elegant flier, known for its soaring flight with occasional slow wingbeats followed by glides. These birds are cooperative feeders, often foraging in groups.

This species is mostly silent but can emit a variety of low-pitched calls, including a deep, quiet croak in flight and deep "moooo" calls at breeding colonies.

Breeding occurs in large colonies with nests varying from stick nests in trees to ground scrapes lined with grass and other materials. The female lays 1 to 4 eggs, with incubation lasting 29 to 36 days. Chicks fledge at 65 to 75 days of age, with sexual maturity reached at 3 to 4 years..

Their diet consists mainly of fish, with daily requirements ranging from 0.9 to 1.4 kg. They feed cooperatively, using their pouches to scoop up water and fish, then contracting the pouch to drain the water and retain the fish. They may also opportunistically consume other birds' chicks and, in some cases, have been observed eating pigeons.

The great white pelican is listed as Least Concern on the IUCN Red List. It is protected under various international agreements and occurs within numerous Important Bird Areas and Special Protection Areas. However, it faces threats from overfishing, habitat loss, and human disturbance.

25-3-2018 TABLE MOUNTAIN AVIARY, CAPE TOWN - AFRICAN HARRIER HAWK (Polyboroides typus)

The African harrier-hawk, or gymnogene, is a medium-sized bird of prey, measuring about 60 to 66 centimeters in length. It is distinguished by its pale grey upperparts, head, and breast, while its belly is white with fine dark barring. The broad wings are pale grey with a distinctive black trailing edge, highlighted by a narrow white line. Its tail is black with a single broad white band. A notable feature is the bare facial patch, which can be red or yellow. Both sexes appear similar, though juveniles display pale brown where adults are grey, and dark brown replaces the black areas.

When observing this raptor, look for the double-jointed ankles, a unique adaptation that allows it to probe into crevices for food. The African harrier-hawk's flight is characterized by its black trailing edge on the wings and the single white band on the tail. The facial patch color can also be a helpful identifier, varying between individuals.

This adaptable bird can be found in a range of habitats including thick rainforests, forest edges, riparian areas, agricultural lands, and even human-occupied areas. It is quite common in traditional rural villages and has been known to breed in palm trees within urban settings.

The African harrier-hawk is widespread across sub-Saharan Africa, with a higher prevalence in the tropical regions of western Africa. Its presence becomes less common towards the eastern and southern parts of the continent.

This species exhibits a fascinating courtship display where pairs may soar together at great heights, often vocalizing. Males may perform undulating flights alone, and when in pairs, they may engage in talon-touching maneuvers. The African harrier-hawk is also known for its intelligence in locating prey by gauging the aggression level of mobbing passerines.

The call of the African harrier-hawk is a distinctive whistled "sueee-sueee-sueee," often heard during flight or courtship displays.

Breeding seasons vary across their range, with March to August in Nigeria and the austral summer in southern regions. Nests are large, circular structures made of sticks and lined with leaves, often reused across seasons. Clutch sizes range from one to three eggs.

An omnivorous diet includes fruit from oil palms and small vertebrates. Its climbing ability and double-jointed legs allow it to raid nests of cavity-nesters for eggs and nestlings. It also preys on introduced species such as feral pigeons and house sparrows.

30-6-2018 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.

30-6-2018 MONTE CORONA, VALENCIA - SPOTTED FLYCATCHER (Muscicapa striata)

The Spotted Flycatcher, Muscicapa striata, is a modestly adorned yet charming small passerine bird belonging to the Old World flycatcher family. It is a migratory species, breeding across Europe and the Palearctic as far as Siberia, and spending the winter months in Africa and southwestern Asia. Despite its widespread presence, there is concern over its decline in certain areas.

Adult Spotted Flycatchers possess grey-brown upperparts and a somewhat pallid underbelly. Their crown and breast are streaked, which is the origin of their common name. They have short, black legs and a black bill shaped to suit their insectivorous diet. Juveniles can be distinguished by their browner plumage and the presence of spots on their upperparts.

These birds favor deciduous woodlands, parks, and gardens, particularly those with open spaces amidst trees.

The Spotted Flycatcher has a broad breeding range, extending from Europe to western Siberia and northwest Africa. During the non-breeding season, they migrate to southern Africa.

25-3-2018 TABLE MOUNTAIN AVIARY, CAPE TOWN - TURKEY VULTURE (Cathartes aura)

The turkey vulture, known scientifically as Cathartes aura, is a bird of prey that is the most widespread of the New World vultures. It is a large bird, with a wingspan of 160–183 cm (63–72 in), a length of 62–81 cm (24–32 in), and weight ranging from 0.8 to 2.41 kg (1.8 to 5.3 lb). The adult turkey vulture is recognized by its bald red head, dark plumage, and a relatively short, hooked, ivory-colored beak. The underwing coverts are silvery-gray, providing a contrast against the darker wing linings.

When observing the turkey vulture in flight, look for its distinctive silhouette with wings held in a shallow V-shape. The bird often rocks or tips from side to side, allowing the silvery-gray flight feathers to catch the light. The small, red head is proportionally small compared to its body, and the beak is short and hooked. The legs and feet are pinkish in color, often stained white due to urohidrosis, a cooling behavior where the bird defecates on its own legs.

Turkey vultures inhabit a variety of open and semi-open areas, including subtropical forests, shrublands, pastures, and deserts. They are often found in areas that juxtapose with woodlands, which are important for nesting and roosting.

The turkey vulture's range extends from southern Canada to the southernmost tip of South America. It is a permanent resident in the southern United States, with northern populations migrating as far south as South America.

Turkey vultures are gregarious and roost in large community groups. They are known for their soaring flight, utilizing thermals to stay aloft with minimal flapping. On the ground, they have an ungainly, hopping walk and require significant effort to take flight. They are also known for their horaltic pose, where they spread their wings to dry, warm their body, or bake off bacteria.

Lacking a syrinx, the turkey vulture's vocalizations are limited to grunts or low hisses.

Breeding season varies with latitude, starting in March in the southern United States and extending into August in northerly latitudes. Turkey vultures nest in protected locations such as cliffs, caves, or hollow trees, laying one to three cream-colored eggs with brown or lavender spots. Both parents incubate and care for the altricial chicks by regurgitating food.

Turkey vultures feed almost exclusively on carrion, preferring recently dead animals and avoiding putrefied remains. They have a keen sense of smell and can detect the gases produced by decaying animals, which aids in locating food.

The turkey vulture is classified as Least Concern by the IUCN Red List. Populations appear stable, and it has not reached the threshold for inclusion as a threatened species.

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.

Red-tailed Hawks are known for their soaring flight, often seen circling high above the ground. They are territorial and can be aggressive, especially during the breeding season. These hawks are solitary hunters but may form pairs or small family groups.

29-6-2018 MONTE CORONA, VALENCIA - STRIPED GRAYLING BUTTERFLY (Hipparchia fidia)

Hipparchia fidia, the striped grayling, is a butterfly of the family Nymphalidae. It is found on the Iberian Peninsula, the Balearic Islands and in south-eastern France and the bordering parts of Italy and North Africa.

S. fidia L. (44 d). Above similar to the preceding [ fatua ], but the underside much more variegated and brighter: the ocelli of the forewing large, broadly bordered with yellow, there being before them white smears which are proximally bordered by a black line.

 On the underside of the hindwing the exterior black discal line projects behind the apex of the cell as a broad tooth; it is externally broadly white and beyond it there are moreover strong white smears extending towards the distal margin.

The wingspan is 48–56 millimetres (1.9–2.2 in).

The butterflies fly from July to August depending on the location.

The larvae feed on various types of grass.

25-3-2018 TABLE MOUNTAIN AVIARY, CAPE TOWN - SPOTTED EAGLE OWL (Bubo africanus)

The Spotted Eagle-Owl, known scientifically as Bubo africanus, is a medium-sized owl and one of the more diminutive members of the eagle owl family. It measures approximately 45 cm (18 inches) in length and weighs between 454 to 907 grams (1.0 to 2.0 pounds), with a wingspan ranging from 100 to 140 cm (39 to 55 inches). This species is distinguished by its off-white to pale ochre facial disk and striking yellow eyes. It boasts prominent ear-tufts, a dusky brown upper body, and off-white lower parts adorned with brown bars.

When attempting to identify the Spotted Eagle-Owl, look for its prominent ear-tufts and the distinctive barring on its chest and belly. The yellow eyes set against the pale facial disk are also key identification features. Its flight is silent and buoyant, typical of owl species.

The Spotted Eagle-Owl is versatile in its choice of habitat. It is commonly found in southern Africa, thriving in both thorn savanna and suburban gardens. It has a particular fondness for rocky outcrops and open areas, where it often roosts on the ground or in tree crowns.

This owl is widespread across sub-Saharan Africa and the Arabian Peninsula. It is the most prevalent owl species in southern Africa and is frequently encountered in urban areas, living in close proximity to human settlements.

The Spotted Eagle-Owl is a solitary and nocturnal bird, known for its typical eagle-owl hoots. The male's call consists of two hoots, "Hooo hooopoooo," while the female responds with three, "Hooo hoo hooo." The young communicate with hisses and beak snaps when threatened. This species is also known to bathe, often seen during summer thunderstorms with wings spread.

The male's two-part hoot and the female's three-part response are characteristic of this species. The young make a rasping noise when hungry, which can be heard over long distances.

Spotted Eagle-Owls are monogamous and breed from late July to early February. They often nest on the ground or in large cavities, including man-made structures. The female lays two to four eggs and incubates them for about 32 days. Owlets leave the nest at around five weeks old and are flight-capable at seven weeks, though they remain dependent on their parents for several weeks thereafter.

The diet of the Spotted Eagle-Owl primarily includes rodents, small mammals, birds, insects, and reptiles. It has a preference for small mammals like rodents and shrews. The owl often swallows prey whole and regurgitates indigestible parts as pellets. It is a generalist feeder and may move to new hunting grounds when prey becomes scarce.

The Spotted Eagle-Owl is classified as Least Concern on the IUCN Red List. It is a common species within its range, but it faces threats from car collisions, electric wires, persecution, secondary poisoning, and parasite infections. Conservation efforts include specialized care for captive owlets and release methods for reintegration into the wild. It is illegal to capture or keep indigenous owls in South Africa without a permit.

25-3-2018 TABLE MOUNTAIN AVIARY, CAPE TOWN - EASTERN GRAY SQUIRREL (Sciurus carolinensis)

The eastern gray squirrel (Sciurus carolinensis), also known, outside of the United States, as the grey squirrel, is a species of tree squirrel in the genus Sciurus. It is native to eastern North America, where it is the most prodigious and ecologically essential natural forest regenerator. Widely introduced to certain places around the world, the eastern gray squirrel in Europe, in particular, is regarded as an invasive species.

In Europe, Sciurus carolinensis is included (since 2016) in the list of Invasive Alien Species of Union concern (the Union list). This implies that this species cannot be imported, bred, transported, commercialized, or intentionally released into the environment in the whole of the European Union.

Sciurus carolinensis is native to the eastern and midwestern United States, and to the southerly portions of the central provinces of Canada. In the mid-1800s the population in the midwestern United States was described as being "truly astonishing," but human predation and habitat destruction through deforestation resulted in drastic population reductions, to the point that the animal was almost absent from Illinois by 1900.

The native range of the eastern gray squirrel overlaps with that of the fox squirrel (Sciurus niger), with which it is sometimes confused, although the core of the fox squirrel's range is slightly more to the west. The eastern gray squirrel is found from New Brunswick, through southwestern Quebec and throughout southern Ontario plus in southern Manitoba, south to East Texas and Florida. Breeding eastern gray squirrels are found in Nova Scotia, but whether this population was introduced or came from natural range expansion is not known.

A prolific and adaptable species, the eastern gray squirrel has also been introduced to, and thrives in, several regions of the western United States and in 1966, this squirrel was introduced onto Vancouver Island in Western Canada in the area of Metchosin, and has spread widely from there. They are considered highly invasive and a threat to both the local ecosystem and the native squirrel, the American red squirrel.

Overseas, eastern gray squirrels in Europe are a concern because they have displaced some of the native squirrels there. They have been introduced into Ireland, Britain, Italy, South Africa, and Australia (where it was extirpated by 1973).

In Ireland, the native squirrel – also colored red – the Eurasian red squirrel S. vulgaris – has been displaced in several eastern counties, though it still remains common in the south and west of the country. The gray squirrel is also an invasive species in Britain; it has spread across the country and has largely displaced the red squirrel. That such a displacement might happen in Italy is of concern, as gray squirrels might spread to other parts of mainland Europe.

25-3-2018 CAPE TOWN, SOUTH AFRICA - EGYPTIAN GOOSE (Alopochen aegyptiaca)

The Egyptian goose is largely terrestrial, capable of perching on trees and buildings. It is known for its aggressive territorial behavior, especially during breeding season, and is not hesitant to engage in aerial combat with intruders. The species is monogamous, with both parents caring for their offspring.

The male's call is a subdued, hoarse quack, becoming louder and more rapid when agitated, resembling a steam engine. The female's quack is raucous and frequently heard, particularly when defending her young.

Nesting occurs in a variety of locations, with a preference for holes in mature trees. Both parents incubate the eggs, and the young are capable of foraging for themselves shortly after hatching.

Egyptian geese primarily consume seeds, leaves, grasses, and plant stems. They may also eat small animals such as locusts and worms. Goslings initially feed on small aquatic invertebrates before transitioning to grazing.

The Egyptian goose is classified as Least Concern by the IUCN, indicating a stable population. However, in regions where it has been introduced, it is considered invasive and may pose a threat to native species.
