The Eskimo curlew (Numenius borealis), also known as northern curlew, is a species of curlew in the family Scolopacidae. It was one of the most numerous shorebirds in the tundra of western Arctic Canada and Alaska. Thousands of birds were then killed per year in the late 1800s. As there has not been a reliable sighting since 1987 or a confirmed sighting since 1963, the Eskimo curlew is considered Critically Endangered or possibly extinct. The bird was about 30 cm (12 in) long and fed mostly on insects and berries. Eskimo curlews are small curlews, about 30 centimeters in length, weighing approximately 360 g, and having a wingspan of 70 cm. Adults have long dark greyish legs and a long bill curved slightly downward. The upperparts are mottled brown and the underparts are light brown. They show cinnamon wing linings in flight. They are similar in appearance to the Hudsonian curlew, the American subspecies of the whimbrel, but smaller in size. (Source: Wikipedia.org, CC BY-SA)
The brown thrasher (Toxostoma rufum), sometimes erroneously called the brown thrush or fox-coloured thrush, is a bird in the family Mimidae, which also includes the New World catbirds and mockingbirds. The brown thrasher is abundant throughout the eastern and central United States and southern and central Canada, and it is the only thrasher to live primarily east of the Rockies and central Texas. It is the state bird of Georgia. As a member of the genus Toxostoma, the bird is relatively large-sized among the other thrashers. It has brown upper parts with a white under part with dark streaks. Because of this, it is often confused with the smaller wood thrush (Hylocichla mustelina), among other species. The brown thrasher is noted for having over 1000 song types, and the largest song repertoire of birds. However, each note is usually repeated in two or three phrases.

The field sparrow (Spizella pusilla) is a small New World sparrow in the family Passerellidae. It is about 140 mm (6 in) long and weighs about 12.5 g (0.4 oz). The head is grey with a rust-coloured crown, white eye-ring and pink bill. The upper parts are brown streaked with black and buff, the breast is buff, the belly is white and the tail is forked. There are two different colour morphs, one being greyer and the other more rufous. The field sparrow is distributed across eastern Canada and the eastern United States, with northern populations migrating southwards to southern United States and Mexico in the fall. The typical habitat of this bird is bushy country with shrubs and grassland. The nest is a cup-shaped construction built on the ground and hidden beneath a bush or clump of grass. The birds forage on the ground or in low vegetation, feeding mainly on seeds and insects. The population is thought to be in slow decline, but it is a common species with a wide range, and the International Union for Conservation of Nature has assessed its conservation status as being of 'least concern'.

The true finches are small to medium-sized passerine birds in the family Fringillidae. Finches have stout conical bills adapted for eating seeds and nuts and often have colourful plumage. They occupy a great range of habitats where they are usually resident and do not migrate. They have a worldwide distribution except for Australia and the polar regions. The family Fringillidae contains more than two hundred species divided into fifty genera. It includes species known as siskins, canaries, redpolls, serins, grosbeaks and euphonias.

The fish crow (Corvus ossifragus) is a species of crow associated with wetland habitats in the eastern and southeastern United States. The fish crow is a small bird, with an average adult weight of 280–320 grams (9.9–11.3 oz) in males and 247–293 grams (8.7–10.3 oz) in females. The average male wingspan is similarly larger at 278–292 millimetres (10.9–11.5 in), compared to 264–277 millimetres (10.4–10.9 in) in females. The total body length is between 36–40 centimetres (14–16 in). The fish crow is superficially similar to the American crow, but is smaller and has a silkier, smoother plumage by comparison. The upperparts have a blue or blue-green sheen, while the underparts have a more greenish tint to the black. The eyes are dark brown. The differences are often only really apparent between the two species when seen side by side or when heard calling. The bill is usually somewhat slimmer than the American crow, but is only readily distinguishable if both species are seen together. (Source: Wikipedia.org, CC BY-SA)
The osprey (Pandion haliaetus), /ˈɒspri, -preɪ/, also called sea hawk, river hawk, and fish hawk, is a diurnal, fish-eating bird of prey with a cosmopolitan range. It is a large raptor reaching more than 60 cm (24 in) in length and 180 cm (71 in) across the wings. It is brown on the upperparts and predominantly greyish on the head and underparts. The osprey tolerates a wide variety of habitats, nesting in any location near a body of water providing an adequate food supply. It is found on all continents except Antarctica, although in South America it occurs only as a non-breeding migrant. As its other common names suggest, the osprey's diet consists almost exclusively of fish. It possesses specialised physical characteristics and unique behaviour in hunting its prey. Its unique characteristics classify it in its own taxonomic genus, Pandion, and family, Pandionidae. (Source: Wikipedia.org, CC BY-SA)
Flamingos or flamingoes /fləˈmɪŋɡoʊz/ are a type of wading bird in the family Phoenicopteridae, which is the only extant family in the order Phoenicopteriformes. There are four flamingo species distributed throughout the Americas (including the Caribbean), and two species native to Afro-Eurasia. A group of flamingoes is called a 'flamboyance.' Flamingos usually stand on one leg with the other tucked beneath the body. The reason for this behaviour is not fully understood. One theory is that standing on one leg allows the birds to conserve more body heat, given that they spend a significant amount of time wading in cold water. However, the behaviour also takes place in warm water and is also observed in birds that do not typically stand in water. An alternative theory is that standing on one leg reduces the energy expenditure for producing muscular effort to stand and balance on one leg. A study on cadavers showed that the one-legged pose could be held without any muscle activity, while living flamingos demonstrate substantially less body sway in a one-legged posture. As well as standing in the water, flamingos may stamp their webbed feet in the mud to stir up food from the bottom. (Source: Wikipedia.org, CC BY-SA)
The double-crested cormorant (Nannopterum auritum) is a member of the cormorant family of water birds. It is found near rivers and lakes, and in coastal areas, and is widely distributed across North America, from the Aleutian Islands in Alaska down to Florida and Mexico. Measuring 70–90 cm (28–35 in) in length, it is entirely black except for a bare patch of orange-yellow facial skin and some extra plumage that it exhibits in the breeding season, when it grows a double crest in which black feathers are mingled with white. Five subspecies are recognized. It mainly eats fish and hunts by swimming and diving. Its feathers, like those of all cormorants, are not waterproof and it must spend time drying them out after spending time in the water. Once threatened by the use of DDT, the numbers of this bird have increased markedly in recent years. (Source: Wikipedia.org, CC BY-SA)
The Florida scrub jay (Aphelocoma coerulescens) is one of the species of scrub jay native to North America. It is the only species of bird endemic to the U.S. state of Florida and one of only 15 species endemic to the continental United States. Because of this, it is keenly sought by birders. It is known to have been present in Florida as a distinct species for at least 2 million years, and is possibly derived from the ancestors of Woodhouse's scrub jay. It measures 23 to 28 cm (9.1 to 11.0 in) in length, and weighs from 66 to 92 g (2.3 to 3.2 oz), with an average 80.2 g (2.83 oz). The wingspan of the jay is 33–36 cm (13–14 in). It has a strong black bill, blue head and nape without a crest, a whitish forehead and supercilium, blue bib, blue wings, grayish underparts, gray back, long blue tail, black legs and feet.

The Old World flycatchers are a large family, the Muscicapidae, of small passerine birds restricted to the Old World (Europe, Africa and Asia), with the exception of several vagrants and two species, bluethroat (Luscinia svecica) and northern wheatear (Oenanthe oenanthe), found also in North America. These are mainly small arboreal insectivores, many of which, as the name implies, take their prey on the wing. The family includes 352 species and is divided into 51 genera.

Guillemot is the common name for several species of seabird in the Alcidae or auk family (part of the order Charadriiformes). In British use, the term comprises two genera: Uria and Cepphus. In North America the Uria species are called murres and only the Cepphus species are called 'guillemots'. This word of French origin derives from a form of the name William, cf. French: Guillaume. The two living species of Uria, together with the razorbill, dovekie, and the extinct great auk, make up the tribe Alcini. They have distinctly white bellies, thicker and longer bills than Cepphus, and form very dense colonies on cliffs during the reproductive season. Guillemot eggs are large (around 11% of female weight), pyriform in shape, and colourful, making them attractive targets for egg collectors. (Source: Wikipedia.org, CC BY-SA)
The fork-tailed flycatcher (Tyrannus savana) is a passerine bird of the tyrant flycatcher family, and is the member of a genus typically referred to as kingbirds. Named for their distinguishingly long, forked tail, fork-tailed flycatchers are seen in lightly forested or grassland areas, from southern Mexico, to south past Argentina. They are most frequently observed sitting on conspicuous perches waiting for flying arthropods to fly past, they then sally out, eat their prey, and return to their perches. Northern populations near southern Mexico tend to be permanent residents, while fork-tailed flycatchers that live further south are migrants with a reputation to wander as far north as the Eastern Seaboard of the United States.

Sabine's gull (/ˈseɪbɪn/ SAY-bin) (Xema sabini) also known as the fork-tailed gull or xeme, is a small gull. It is the only species placed in the genus Xema. It breeds in colonies on coasts and tundra, laying two or three spotted olive-brown eggs in a ground nest lined with grass. Sabine's gull is pelagic outside the breeding season. It takes a wide variety of mainly animal food, and will eat any suitable small prey. This species is easy to identify through its striking wing pattern. The adult has a pale grey back and wing coverts, black primary flight feathers and white secondaries. The white tail is forked. The male's hood darkens during breeding season. Young birds have a similar tricoloured wing pattern, but the grey is replaced by brown, and the tail has a black terminal band. Juveniles take two years to attain full adult plumage. Sabine's gulls have an unusual molt pattern for gulls. Fledged birds retain their juvenile plumage through the autumn and do not start molting into their first winter plumage until they have reached their wintering grounds. Adults have their complete molt in the spring prior to the spring migration, and have a partial molt in the autumn after returning to the wintering area, a reversal of the usual pattern for gulls. They have a very high-pitched and squeaking call. (Source: Wikipedia.org, CC BY-SA)
The fork-tailed storm petrel (Hydrobates furcatus) is a small seabird of the storm petrel family Hydrobatidae. It is the second-most abundant and widespread storm petrel (after Leach's storm petrel) and is the only bird in its family that is bluish-grey in colour. The fork-tailed storm petrel is pelagic, spending up to 8 months in the northern Pacific Ocean. They only return to land to breed, where they nest in a single colony. Their nests can be found in a rock crevice or small burrow, where a single egg is laid. Their breeding range is along the coast of the northern Pacific Ocean, extending from northern California to northeast Asia. They mainly feed on planktonic crustaceans, small fish, and squid, but also consume offal. Similarly to other storm petrels, they forage by picking food off the surface of the water while in flight.

Moorhens, sometimes called marsh hens—are medium-sized water birds that are members of the rail family (Rallidae). Most species are placed in the genus Gallinula, Latin for 'little hen'. They are close relatives of coots. They are often referred to as (black) gallinules. Recently, one of the species of Gallinula was found to have enough differences to form a new genus Paragallinula with the only species being the lesser moorhen (Paragallinula angulata). Two species from the Australian region, sometimes separated in Tribonyx, are called 'native hens' (also native-hen or nativehen). The native hens differ visually by shorter, thicker and stubbier toes and bills, and longer tails that lack the white signal pattern of typical moorhens. (Source: Wikipedia.org, CC BY-SA)
Frigatebirds are a family of seabirds called Fregatidae which are found across all tropical and subtropical oceans. The five extant species are classified in a single genus, Fregata. All have predominantly black plumage, long, deeply forked tails and long hooked bills. Females have white underbellies and males have a distinctive red gular pouch, which they inflate during the breeding season to attract females. Their wings are long and pointed and can span up to 2.3 metres (7.5 ft), the largest wing area to body weight ratio of any bird. Able to soar for weeks on wind currents, frigatebirds spend most of the day in flight hunting for food, and roost on trees or cliffs at night. Their main prey are fish and squid, caught when chased to the water surface by large predators such as tuna. Frigatebirds are referred to as kleptoparasites as they occasionally rob other seabirds for food, and are known to snatch seabird chicks from the nest. Seasonally monogamous, frigatebirds nest colonially. A rough nest is constructed in low trees or on the ground on remote islands. A single egg is laid each breeding season. The duration of parental care is among the longest of any bird species; frigatebirds are only able to breed every other year. (Source: Wikipedia.org, CC BY-SA)
The fulmarine petrels or fulmar-petrels are a distinct group of petrels within the family Procellariidae. They are the most variable of the four groups within the Procellariidae, differing greatly in size and biology. They do, however, have a unifying feature, their skull, and in particular their nasal tubes. They are predominantly found in the Southern Ocean with one species, the northern fulmar, ranging in the North Pacific and Atlantic Oceans. Fossils of fulmarine petrels dating back to the Upper Miocene have been found in Menorca. (Source: Wikipedia.org, CC BY-SA)
The gadwall (Mareca strepera) is a common and widespread dabbling duck in the family Anatidae. The gadwall is 47–58 cm (19–23 in) long with a 78–85 cm (31–33 in) wingspan. The male is slightly larger than the female, weighing on average 990 g (35 oz) against her 850 g (30 oz). The breeding male is patterned grey, with a black rear end, light chestnut wings, and a brilliant white speculum, obvious in flight or at rest. In non-breeding (eclipse) plumage, the drake looks more like the female, but retains the male wing pattern, and is usually greyer above and has less orange on the bill. The female is light brown, with plumage much like a female mallard. It can be distinguished from that species by the dark orange-edged bill, smaller size, the white speculum, and white belly. Both sexes go through two moults annually, following a juvenile moult. (Source: Wikipedia.org, CC BY-SA)
Gannets are seabirds comprising the genus Morus in the family Sulidae, closely related to boobies. Gannets are large white birds with yellowish heads, black-tipped wings and long bills. Northern gannets are the largest seabirds in the North Atlantic, having a wingspan of up to two metres (6+1⁄2 feet). The other two species occur in the temperate seas around southern Africa, southern Australia, and New Zealand. Gannets are colonial breeders on islands and coasts, normally laying one chalky-blue egg. They lack brood patches and use their webbed feet to warm the eggs. They reach maturity around 5 years of age. First-year birds are completely black, and subsequent subadult plumages show increasing amounts of white. (Source: Wikipedia.org, CC BY-SA)
The glossy ibis (Plegadis falcinellus) is a water bird in the order Pelecaniformes and the ibis and spoonbill family Threskiornithidae. The scientific name derives from Ancient Greek plegados and Latin, falcis, both meaning 'sickle' and referring to the distinctive shape of the bill. This species is a mid-sized ibis. It is 48–66 cm (19–26 in) long, averaging around 59.4 cm (23.4 in) with an 80–105 cm (31–41 in) wingspan. The culmen measures 9.7 to 14.4 cm (3.8 to 5.7 in) in length, each wing measures 24.8–30.6 cm (9.8–12.0 in), the tail is 9–11.2 cm (3.5–4.4 in) and the tarsus measures 6.8–11.3 cm (2.7–4.4 in). The body mass of this ibis can range from 485 to 970 g (1.069 to 2.138 lb). Breeding adults have reddish-brown bodies and shiny bottle-green wings. Non-breeders and juveniles have duller bodies. This species has a brownish bill, dark facial skin bordered above and below in blue-gray (non-breeding) to cobalt blue (breeding), and red-brown legs. Unlike herons, ibises fly with necks outstretched, their flight being graceful and often in V formation. It also has shiny feathers. (Source: Wikipedia.org, CC BY-SA)
The golden eagle (Aquila chrysaetos) is a bird of prey living in the Northern Hemisphere. It is the most widely distributed species of eagle. Like all eagles, it belongs to the family Accipitridae. They are one of the best-known birds of prey in the Northern Hemisphere. These birds are dark brown, with lighter golden-brown plumage on their napes. Immature eagles of this species typically have white on the tail and often have white markings on the wings. Golden eagles use their agility and speed combined with powerful feet and large, sharp talons to hunt a variety of prey, mainly hares, rabbits, and marmots and other ground squirrels. Golden eagles maintain home ranges or territories that may be as large as 200 km2 (77 sq mi). They build large nests in cliffs and other high places to which they may return for several breeding years. Most breeding activities take place in the spring; they are monogamous and may remain together for several years or possibly for life. Females lay up to four eggs, and then incubate them for six weeks. Typically, one or two young survive to fledge in about three months. These juvenile golden eagles usually attain full independence in the fall, after which they wander widely until establishing a territory for themselves in four to five years.

The American golden plover (Pluvialis dominica), is a medium-sized plover. The genus name is Latin and means relating to rain, from pluvia, 'rain'. It was believed that golden plovers flocked when rain was imminent. The species name dominica refers to Santo Domingo, now Hispaniola, in the West Indies. American golden plover and picked up the spores while lining their nests. Then when the birds arrive in new places they molt, leaving behind the feathers and their precious cargo to start growing again at the other end of the world. The breeding adult American golden plover has a black face, neck, breast, and belly, with a white crown and nape that extends to the side of the breast. The back is mottled black and white with pale, gold spots. The breeding female is similar, but with less black. When in winter plumage, both sexes have grey-brown upperparts, pale grey-brown underparts, and a whitish eyebrow. The head is small, along with the bill. (Source: Wikipedia.org, CC BY-SA)
The thrushes are a passerine bird family, Turdidae, with a worldwide distribution. The family was once much larger before biologists reclassified the former subfamily Saxicolinae, which includes the chats and European robins, as Old World flycatchers. Thrushes are small to medium-sized ground living birds that feed on insects, other invertebrates and fruit. Some unrelated species around the world have been named after thrushes due to their similarity to birds in this family. Thrushes are plump, soft-plumaged, small to medium-sized birds, inhabiting wooded areas, and often feeding on the ground. The smallest thrush may be the forest rock thrush, at 21 g (3⁄4 oz) and 14.5 cm (5+3⁄4 in). However, the shortwings, which have ambiguous alliances with both thrushes and Old World flycatchers, can be even smaller. The lesser shortwing averages 12 cm (4+1⁄2 in). The largest thrush is the Great thrush at 128 to 175 g (4+1⁄2 to 6+1⁄8 oz) and 28 to 33 cm (11 to 13 in), though the commonly recognized Blue whistling-thrush is an Old world flycatcher. The Amami thrush might, however, grow larger than the Great thrush. Most species are grey or brown in colour, often with speckled underparts. (Source: Wikipedia.org, CC BY-SA)
The common goldeneye or simply goldeneye (Bucephala clangula) is a medium-sized sea duck of the genus Bucephala, the goldeneyes. Its closest relative is the similar Barrow's goldeneye. The genus name is derived from the Ancient Greek boukephalos ('bullheaded', from bous, 'bull ' and kephale, 'head'), a reference to the bulbous head shape of the bufflehead. The species name is derived from the Latin clangere ('to resound'). Common goldeneyes are aggressive and territorial ducks, and have elaborate courtship displays. Adult males ranges from 45–51 cm (18–20 in) and weigh approximately 1,000 g (2.2 lb), while females range from 40–50 cm (16–20 in) and weigh approximately 800 g (1.8 lb). The common goldeneye has a wingspan of 30.3-32.7 in (77-83 cm). The species is named for its golden-yellow eye. Adult males have a dark head with a greenish gloss and a circular white patch below the eye, a dark back and a white neck and belly. Adult females have a brown head and a mostly grey body. Their legs and feet are orange-yellow. (Source: Wikipedia.org, CC BY-SA)
The black-rumped flameback (Dinopium benghalense), also known as the lesser golden-backed woodpecker or lesser goldenback, is a woodpecker found widely distributed in the Indian subcontinent. It is one of the few woodpeckers that are seen in urban areas. It has a characteristic rattling-whinnying call and an undulating flight. It is the only golden-backed woodpecker with a black throat and a black rump. The black-rumped flameback is a large species at 26–29 cm in length. It has a typical woodpecker shape, and the golden yellow wing coverts are distinctive. The rump is black and not red as in the greater flameback. The underparts are white with dark chevron markings. The black throat finely marked with white immediately separates it from other golden backed woodpeckers in the Indian region. The head is whitish with a black nape and throat, and there is a greyish eye patch. Unlike the greater flameback it has no dark moustachial stripes. The adult male has a red crown and crest. Females have a black forecrown spotted with white, with red only on the rear crest. Young birds are like the female, but duller. (Source: Wikipedia.org, CC BY-SA)
The common merganser (North American) or goosander (Eurasian) (Mergus merganser) is a large seaduck of rivers and lakes in forested areas of Europe, Asia, and North America. The common merganser eats mainly fish. It nests in holes in trees. It is 58–72 cm (23–28+1⁄2 in) long with a 78–97 cm (30+1⁄2–38 in) wingspan and a weight of 0.9–2.1 kg (2 lb 0 oz – 4 lb 10 oz); males average slightly larger than females, but with some overlap. Like other species in the genus Mergus, it has a crest of longer head feathers, but these usually lie smoothly rounded behind the head, not normally forming an erect crest. Adult males in breeding plumage are easily distinguished, the body white with a variable salmon-pink tinge, the head black with an iridescent green gloss, the rump and tail grey, and the wings largely white on the inner half, black on the outer half. Females and males in 'eclipse' (non-breeding plumage, July to October) are largely grey, with a reddish-brown head, white chin, and white secondary feathers on the wing. Juveniles (both sexes) are similar to adult females but also show a short black-edged white stripe between the eye and bill. The bill and legs are red to brownish-red, brightest on adult males, dullest on juveniles. (Source: Wikipedia.org, CC BY-SA)
The wedge-tailed grass finch (Emberizoides herbicola) is a species of bird in the family Thraupidae; it was formerly placed in the Emberizidae. It is found in Argentina, Bolivia, Brazil, Colombia, Costa Rica, Ecuador, French Guiana, Guyana, Panama, Paraguay, Peru, Suriname, Uruguay, and Venezuela. Its major range is in southeastern South America in southern Brazil, Bolivia, eastern Paraguay, and extreme northeast Argentina in the cerrado, pantanal, and southern caatinga; it also ranges into northern Colombia with central Venezuela, and the Atlantic coastal Guianas, as well as Ilha de Marajo at the Amazon River outlet. Its natural habitats are dry savanna, subtropical or tropical seasonally wet or flooded lowland grassland, and heavily degraded former forest. (Source: Wikipedia.org, CC BY-SA)
The chicken (Gallus gallus domesticus) is a domesticated junglefowl species, with attributes of wild species such as the grey and the Ceylon junglefowl that are originally from Southeast Asia. Rooster and cock are terms for adult male birds, and a younger male may be called a cockerel. A male that has been castrated is a capon. An adult female bird is called a hen, and a sexually immature female is called a pullet. Humans keep chickens primarily as a source of food (consuming both their meat and eggs) or as pets. Traditionally they were also bred for cockfighting, which is still practiced in some places. Chickens domesticated for meat are broilers and for eggs are layers. Chickens are one of the most common and widespread domestic animals, with a total population of 23.7 billion as of 2018, up from more than 19 billion in 2011. There are more chickens in the world than any other bird. There are numerous cultural references to chickens—in myth, folklore and religion, and in language and literature.

The great auk (Pinguinus impennis) is a species of flightless alcid that became extinct in the mid-19th century. It was the only modern species in the genus Pinguinus. It is not closely related to the birds now known as penguins, which were discovered later by Europeans and so named by sailors because of their physical resemblance to the great auk. It bred on rocky, remote islands with easy access to the ocean and a plentiful food supply, a rarity in nature that provided only a few breeding sites for the great auks. When not breeding, they spent their time foraging in the waters of the North Atlantic, ranging as far south as northern Spain and along the coastlines of Canada, Greenland, Iceland, the Faroe Islands, Norway, Ireland, and Great Britain.

The Carolina wren (Thryothorus ludovicianus) is a common species of wren that is a resident in the eastern half of the United States of America, the extreme south of Ontario, Canada, and the extreme northeast of Mexico. Severe winters restrict the northern limits of their range, while favorable weather conditions lead to a northward extension of their breeding range. Their preferred habitat is in dense cover in forest, farm edges, and suburban areas. This wren is the state bird of South Carolina. Seven recognized subspecies occur across the range of these wrens and they differ slightly in song and appearance. The birds are generally inconspicuous, avoiding the open for extended periods of time. When out in the open, they investigate their surroundings and are rarely stationary. After finding a mate, pairs maintain a territory and stay together for several years. Both males and females give out alarm calls, but only males sing to advertise territory. Carolina wrens raise multiple broods during the summer breeding season, but can fall victim to brood parasitism by brown-headed cowbirds, among other species. Some populations have been affected by mercury contamination. (Source: Wikipedia.org, CC BY-SA)
The cinereous owl (Strix sartorii) or Mexican barred owl, is an owl that is endemic to Mexico. Very few specimens of cinereous owl have been measured. The limited number of measurements indicate lengths between 430 and 505 cm (14.11 and 16.57 ft), male weights between 469 and 812 g (1.034 and 1.790 lb), and female weights between 610 and 1,051 g (1.345 and 2.317 lb) This large round-headed owl's upperparts are brownish gray with whitish to buff bars. It has grayish white to browish gray facial disks surrounded by darker brown and buffy bars. Its underparts are pale buff to white with dark streaks. (Source: Wikipedia.org, CC BY-SA)
The great crested flycatcher (Myiarchus crinitus) is a large insect-eating bird of the tyrant flycatcher family. It is the most widespread member of the genus Myiarchus in North America, and is found over most of the eastern and mid-western portions of the continent. It dwells mostly in the treetops and rarely is found on the ground. Adult great crested flycatchers usually measure between 17–21 cm (6.7–8.3 in) in length with a wingspan of around 34 cm (13 in). This bird usually weighs between 27–40 g (0.95–1.41 oz). The great crested flycatcher does not display sexual dimorphism. All adults are brownish on the upperparts with yellow underparts; they have a long rusty brown tail and a bushy crest. Their throat and breast are grey. (Source: Wikipedia.org, CC BY-SA)
The great black hawk (Buteogallus urubitinga) is a bird of prey in the family Accipitridae, which also includes the eagles, hawks, and Old World vultures. The adult great black hawk is 56 to 64 centimetres (22 to 25 in) long and weighs 1.1 kilograms (2 lb 7 oz). It resembles the common black hawk, but is larger with a different call and tail pattern. It has very broad wings, and is mainly black. The short tail is white with a broad black tip. The bill is black and the legs and cere are yellow. The sexes are similar, but immature birds are dark brown above with spotting and streaks. Their underparts are buff with dark spots, and the tail has a number of black and dusky bars. The call of great black hawk is a distinctive piping ooo-wheeeeee. (Source: Wikipedia.org, CC BY-SA)
The great horned owl (Bubo virginianus), also known as the tiger owl (originally derived from early naturalists' description as the 'winged tiger' or 'tiger of the air'), or the hoot owl, is a large owl native to the Americas. It is an extremely adaptable bird with a vast range and is the most widely distributed true owl in the Americas. Its primary diet is rabbits and hares, rats and mice, and voles, although it freely hunts any animal it can overtake, including rodents and other small mammals, larger mid-sized mammals, birds, reptiles, amphibians, and invertebrates. In ornithological study, the great horned owl is often compared to the Eurasian eagle-owl (Bubo bubo), a closely related species, which despite the latter's notably larger size, occupies the same ecological niche in Eurasia, and the red-tailed hawk (Buteo jamaicensis), with which it often shares similar habitat, prey, and nesting habits by day, thus is something of a diurnal ecological equivalent. The great horned owl is one of the earliest nesting birds in North America, often laying eggs weeks or even months before other raptorial birds. (Source: Wikipedia.org, CC BY-SA)
The marbled godwit (Limosa fedoa) is a large migratory shorebird in the family Scolopacidae. On average, it is the largest of the four species of godwit. The total length is 40–50 cm (16–20 in), including a large bill of 8–13 cm (3.1–5.1 in), and wingspan is 70–88 cm (28–35 in). Body mass can vary from 240 to 520 g (8.5 to 18.3 oz). The average weight of 40 males was 326 g (11.5 oz) and that of 45 females was 391 g (13.8 oz). Bill length is from 73.9 to 131 mm (2.91 to 5.16 in). Among all the members of the sandpiper family, only the curlews attain sizes that significantly exceed this species. Adults have long blue-grey legs and a very long pink bill with a slight upward curve and dark at the tip. The long neck, breast and belly are pale brown with dark bars on the breast and flanks. The back is mottled and dark. They show cinnamon wing linings in flight. (Source: Wikipedia.org, CC BY-SA)
The common loon or great northern diver (Gavia immer) is a large member of the loon, or diver, family of birds. Breeding adults have a plumage that includes a broad black head and neck with a greenish, purplish, or bluish sheen, blackish or blackish-grey upperparts, and pure white underparts except some black on the undertail coverts and vent. Non-breeding adults are brownish with a dark neck and head marked with dark grey-brown. Their upperparts are dark brownish-grey with an unclear pattern of squares on the shoulders, and the underparts, lower face, chin, and throat are whitish. The sexes look alike, though males are significantly heavier than females. During the breeding season, loons live on lakes and other waterways in Canada; the northern United States (including Alaska); and southern parts of Greenland and Iceland. Small numbers breed on Svalbard and sporadically elsewhere in Arctic Eurasia. Common loons winter on both coasts of the US as far south as Mexico, and on the Atlantic coast of Europe.

The greater crested tern (Thalasseus bergii), also called crested tern or swift tern, is a tern in the family Laridae that nests in dense colonies on coastlines and islands in the tropical and subtropical Old World. Its five subspecies breed in the area from South Africa around the Indian Ocean to the central Pacific and Australia, all populations dispersing widely from the breeding range after nesting. This large tern is closely related to the royal and lesser crested terns, but can be distinguished by its size and bill colour. The greater crested tern has grey upperparts, white underparts, a yellow bill, and a shaggy black crest that recedes in winter. Its young have a distinctive appearance, with strongly patterned grey, brown and white plumage, and rely on their parents for food for several months after they have fledged. Like all members of the genus Thalasseus, the greater crested tern feeds by plunge diving for fish, usually in marine environments; the male offers fish to the female as part of the courtship ritual.

The great egret (Ardea alba), also known as the common egret, large egret, or (in the Old World) great white egret or great white heron is a large, widely distributed egret. The four subspecies are found in Asia, Africa, the Americas, and southern Europe. Recently it is also spreading to more northern areas of Europe. Distributed across most of the tropical and warmer temperate regions of the world, it builds tree nests in colonies close to water. The great egret is a large heron with all-white plumage. Standing up to 1 m (3.3 ft) tall, this species can measure 80 to 104 cm (31 to 41 in) in length with a wingspan of 131 to 170 cm (52 to 67 in). Body mass can range from 700 to 1,500 g (1.5 to 3.3 lb), with an average around 1,000 g (2.2 lb). It is thus only slightly smaller than the great blue or grey heron (A. cinerea). Apart from size, the great egret can be distinguished from other white egrets by its yellow bill and black legs and feet, though the bill may become darker and the lower legs lighter in the breeding season. In breeding plumage, delicate ornamental feathers are borne on the back. Males and females are identical in appearance; juveniles look like nonbreeding adults. Differentiated from the intermediate egret (Ardea intermedia) by the gape, which extends well beyond the back of the eye in case of the great egret, but ends just behind the eye in case of the intermediate egret.

The great blue heron (Ardea herodias) is a large wading bird in the heron family Ardeidae, common near the shores of open water and in wetlands over most of North America and Central America, as well as far northwestern South America, the Caribbean and the Galápagos Islands. It is a rare vagrant to coastal Spain, the Azores, and areas of far southern Europe. An all-white population found in south Florida and the Florida Keys is known as the great white heron. Debate exists about whether this represents a white color morph of the great blue heron, a subspecies of it, or an entirely separate species. (Source: Wikipedia.org, CC BY-SA)
