25-3-2018 TABLE MOUNTAIN AVIARY, CAPE TOWN - MEERKAT (Suricata suricatta)
The meerkat (Suricata suricatta) or suricate is a small mongoose found in southern Africa. It is characterised by a broad head, large eyes, a pointed snout, long legs, a thin tapering tail, and a brindled coat pattern. The head-and-body length is around 24–35 cm (9.4–13.8 in), and the weight is typically between 0.62 and 0.97 kg (1.4 and 2.1 lb). The coat is light grey to yellowish-brown with alternate, poorly-defined light and dark bands on the back. Meerkats have foreclaws adapted for digging and have the ability to thermoregulate to survive in their harsh, dry habitat. Three subspecies are recognised.
Meerkats are highly social, and form packs of two to 30 individuals each that occupy home ranges around 5 km2 (1.9 sq mi) in area. There is a social hierarchy—generally dominant individuals in a pack breed and produce offspring, and the nonbreeding, subordinate members provide altruistic care to the pups. Breeding occurs around the year, with peaks during heavy rainfall; after a gestation of 60 to 70 days, a litter of three to seven pups is born.
They live in rock crevices in stony, often calcareous areas, and in large burrow systems in plains. The burrow systems, typically 5 m (16 ft) in diameter with around 15 openings, are large underground networks consisting of two to three levels of tunnels. These tunnels are around 7.5 cm (3.0 in) high at the top and wider below, and extend up to 1.5 m (4 ft 11 in) into the ground. Burrows have moderated internal temperatures and provide a comfortable microclimate that protects meerkats in harsh weather and at extreme temperatures.
Meerkats are active during the day, mostly in the early morning and late afternoon; they remain continuously alert and retreat to burrows when sensing danger. They use a broad variety of calls to communicate among one another for different purposes, for example to raise an alarm on sighting a predator. Primarily insectivorous, meerkats feed heavily on beetles and lepidopterans, arthropods, amphibians, small birds, reptiles, and plant material in their diet.
Commonly living in arid, open habitats with little woody vegetation, meerkats occur in southwestern Botswana, western and southern Namibia, and northern and western South Africa; the range barely extends into southwestern Angola. With no significant threats to the population, the meerkat is listed as Least Concern on the IUCN Red List. Meerkats are widely depicted in television, movies and other media.
25-3-2018 TABLE MOUNTAIN AVIARY, CAPE TOWN - SPOTTED THICK NEE (Burhinus capensis)
The Spotted Thick-knee, also known as the Spotted Dikkop or Cape Thick-knee, is a bird of notable stature, reaching up to 45.5 cm in height. It is adorned with brown-and-white speckled plumage that blends seamlessly into the grasslands and savannas it calls home. The bird's head is large and round, crowned with a prominent yellow eye, while its short, stout beak is well-suited to its diet. In flight or when displaying its characteristic wings-raised stance, it reveals a striking contrast in its plumage. Its legs are long and yellow, and the tibiotarsal joint is notably expanded, a feature that has given rise to its common name.
.
To identify the Spotted Thick-knee, look for its long yellow legs and the distinctive thickening at the knee joint. Its camouflage plumage can make it challenging to spot, but the bird's large, round head and prominent yellow eyes are key distinguishing features. When it takes to the air or assumes its unique pose with wings aloft, the contrasting patterns of its plumage become quite apparent.
This species thrives in the grasslands and savannas, where its mottled plumage provides excellent camouflage against the backdrop of these ecosystems.
The Spotted Thick-knee is native to sub-Saharan Africa, with a range that spans from Senegal, Mali, and Mauritania in the west, across to Ethiopia, Kenya, Tanzania, and down to South Africa in the east and south. It is also found in south Yemen.
The Spotted Thick-knee is a nocturnal creature, often squatting on the ground during the day, which makes it quite elusive. It is a ground hunter, preying on insects, small mammals, and lizards.
The Spotted Thick-knee lays usually two eggs, with a two-day interval between them. The eggs are marked with sepia brown and ash grey on a pale, clay-coloured background. Nesting occurs on the ground, with a scrape lined with grasses, feathers, pebbles, and twigs. Both male and female parents are involved in rearing the young, bringing food to the nest and defending it vigorously. They may even feign injury to distract predators from their offspring.
The Spotted Thick-knee can be confused with the Water Thick-knee but can be distinguished by the distinct wing pattern of the Water Thick-knee.
The diet of the Spotted Thick-knee consists of insects, small mammals, and lizards, which it hunts on the ground.
The Spotted Thick-knee is classified as "Least Concern" by the IUCN, thanks to its extensive range and stable population numbers.
25-3-2018 TABLE MOUNTAIN AVIARY, CAPE TOWN - EUROPEAN STARLING (Sturnus vulgaris)
The Common Starling, Sturnus vulgaris, is a medium-sized passerine bird characterized by its glossy black plumage with a metallic sheen. Throughout the year, the plumage is speckled with white, though less so during the breeding season. Adults measure approximately 20 cm in length, with pink legs and a seasonally changing bill color—black in winter and yellow in summer. Juveniles display browner plumage compared to adults.
To identify the Common Starling, look for its iridescent black feathers, which may appear purple or green when reflecting light. The bird's bill is black in the winter and transitions to yellow in the summer, aiding in identification. The starling's flight is strong and direct, with pointed wings that are distinctive in the air. On the ground, its waddling gait is notable.
Common Starlings are highly adaptable, favoring urban and suburban areas where they find ample nesting and roosting opportunities. They also inhabit grasslands, such as farmlands and pastures, where short grass makes foraging for invertebrates easier.
Native to temperate Europe and western Asia, the Common Starling has been introduced to Australia, New Zealand, North America, and other regions. Its range extends from Europe to northern Africa and across the Palearctic to western Mongolia.
The Common Starling is a gregarious bird, especially in autumn and winter, forming large flocks known as murmurations. These flocks are thought to be a defense against predators. On the ground, starlings forage in groups, often following grazing animals to feed on disturbed invertebrates.
The Common Starling's song is a varied mix of melodic and mechanical sounds, including mimicked noises from other bird species and the environment. Males sing to attract mates and defend their territory. Calls include a harsh alarm scream and a variety of social chatters.
Breeding occurs in the spring and summer, with the female laying four to five glossy, pale blue eggs in a nest built within a natural or artificial cavity. Both parents share incubation duties, and the young fledge after about three weeks.
Omnivorous, the Common Starling's diet includes a wide range of invertebrates, seeds, and fruit. They employ various foraging techniques, such as probing the ground and catching flying insects.
25-3-2018 TABLE MOUNTAIN AVIARY, CAPE TOWN - WOOD DUCK (FEMALE) (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.

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.

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)
%2020.jpg)
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.
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 - 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 - 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 - RED TAILED HAWK (Buteo jamaicensis)
