The black guillemot or tystie (Cepphus grylle) is a medium-sized seabird of the Alcidae family, native throughout northern Atlantic coasts and eastern North American coasts. It is resident in much of its range, but large populations from the high arctic migrate southwards in winter. The bird can be seen in and around its breeding habitat of rocky shores, cliffs and islands in single or smalls groups of pairs. They feed mainly by diving towards the sea floor feeding on fish, crustaceans or other benthic invertebrates. They are listed on the IUCN red list as a species of least concern. Both sexes have very similar appearances with black plumage and a large white patch on the upper side of their wings in summer. The bill is also black, being rather long and slender, while the feet are coral-red. In winter adult underparts are white and the upperparts are a pale grey with the back and shoulders exhibiting barred light grey and white patterning. (Source: Wikipedia.org, CC BY-SA)
The black skimmer (Rynchops niger) is a tern-like seabird, one of three similar birds species in the skimmer genus Rynchops in the gull family Laridae. It breeds in North and South America. Northern populations winter in the warmer waters of the Caribbean and the tropical and subtropical Pacific coasts, but the South American races make only shorter movements in response to annual floods which extend their feeding areas in the river shallows.

The black tern (Chlidonias niger) is a small tern generally found in or near inland water in Europe, Western Asia and North America. As its name suggests, it has predominantly dark plumage. In some lights it can appear blue in the breeding season, hence the old English name 'blue darr'. The genus name is from Ancient Greek khelidonios, 'swallow-like', from khelidon, 'swallow': another old English name for the black tern is 'carr (i.e. lake) swallow'. The species name is from Latin niger 'shining black'. (Source: Wikipedia.org, CC BY-SA)
The black vulture (Coragyps atratus), also known as the American black vulture, Mexican vulture, zopilote, urubu, or gallinazo, is a bird in the New World vulture family whose range extends from the northeastern United States to Perú, Central Chile and Uruguay in South America. Although a common and widespread species, it has a somewhat more restricted distribution than its compatriot, the turkey vulture, which breeds well into Canada and all the way south to Tierra del Fuego. It is the only extant member of the genus Coragyps, which is in the family Cathartidae. Despite the similar name and appearance, this species is unrelated to the Eurasian black vulture, an Old World vulture, of the family Accipitridae (which includes raptors like the eagles, hawks, kites, and harriers). For ease of locating animal corpses (their main source of sustenance), black vultures tend to inhabit relatively open areas with scattered trees, such as chaparral, in addition to subtropical forested areas and parts of the Brazilian pantanal.

The black harrier (Circus maurus) is a medium-sized African harrier whose range extends from South Africa to Botswana and Namibia. It has a wingspan of 105–115 cm (41–45 in) and a body length of 44–50 cm (17–20 in). When perched, this bird appears all black. However, in flight a white rump and flight feathers become visible. Its morphology is comparable to that of other harriers, with a slim body, narrow wings and a long tail. Male and female plumages are similar. Juveniles have buff under-parts and heavily spotted breasts. (Source: Wikipedia.org, CC BY-SA)
The dickcissel (Spiza americana) is a small seed-eating migratory bird in the family Cardinalidae. It breeds on the prairie grasslands of the Midwestern United States and winters in Central America, northern Colombia, and northern Venezuela. It is the only member of the genus Spiza, though some sources list another supposedly extinct species. Dickcissels have a large, pale bill, a yellow line over the eyes, brownish upperparts with black streaks on the back, dark wings, a rust patch on the shoulders, and light underparts. Adult males have a black throat patch, a yellow breast, and grey cheeks and crown. This head and breast pattern is especially brilliant in the breeding plumage, making it resemble an eastern meadowlark. Females and juveniles are brownish on the cheeks and crown, and are somewhat similar in appearance to house sparrows; they have streaked flanks. (Source: Wikipedia.org, CC BY-SA)
The black-throated loon (Gavia arctica), also known as the Arctic loon and the black-throated diver, is a migratory aquatic bird found in the northern hemisphere, primarily breeding in freshwater lakes in northern Europe and Asia. It winters along sheltered, ice-free coasts of the north-east Atlantic Ocean and the eastern and western Pacific Ocean. This loon was first described by Carl Linnaeus in 1758. It has two subspecies. It was previously considered to be the same species as the Pacific loon, of which it is traditionally considered to be a sister species, although this is debated. In a study that used mitochondrial and nuclear intron DNA, the black-throated loon was found to be sister to a clade consisting of the Pacific loon and two sister species, the common loon and the yellow-billed loon.

The broad-winged hawk (Buteo platypterus) is a medium-sized hawk of the genus Buteo. During the summer, some subspecies are distributed over eastern North America, as far west as British Columbia and Texas; they then migrate south to winter in the Neotropics from Mexico south to southern Brazil. Other subspecies are all-year residents on Caribbean islands. As in most raptors, females are slightly larger than males. Broad-winged hawks' wings are relatively short and broad with a tapered, somewhat pointed appearance. The two types of coloration are a dark morph with fewer white areas and a light morph that is more pale overall. Although the broad-winged hawk's numbers are relatively stable, populations are declining in some parts of its breeding range because of forest fragmentation. (Source: Wikipedia.org, CC BY-SA)
The Oriental darter (Anhinga melanogaster) is a water bird of tropical South Asia and Southeast Asia. It has a long and slender neck with a straight, pointed bill and, like the cormorant, it hunts for fish while its body is submerged in water. It spears a fish underwater, bringing it above the surface, tossing and juggling it before swallowing the fish head first. The body remains submerged as it swims, and the slender neck alone is visible above the water, which accounts for the colloquial name of snakebird. Like the cormorants, it has wettable feathers and it is often found perched on a rock or branch with its wings held open to dry. The Oriental darter is like all other anhingas, a cormorant-like species that has a very long neck. The structure of the neck is as in other species of darter with strongly developed muscles about a kink in the neck at the 8th and 9th vertebrae that allows it to be flexed and darted forward with rapid force to stab fish underwater. The edges of the commissures of the mandible tips have minute inward pointing serrations that hold impaled fish. (Source: Wikipedia.org, CC BY-SA)
The grey plover or black-bellied plover (Pluvialis squatarola) is a large plover breeding in Arctic regions. It is a long-distance migrant, with a nearly worldwide coastal distribution when not breeding. The grey plover is 27–30 cm (11–12 in) long with a wingspan of 71–83 cm (28–33 in) and a weight of 190–280 g (6.7–9.9 oz) (up to 345 g (12.2 oz) in preparation for migration). In spring and summer (late April or May to August), adults are spotted black and white on the back and wings. The face and neck are black with a white border; they have a black breast and belly and a white rump. The tail is white with black barring. The bill and legs are black. They moult to winter plumage in mid August to early September and retain this until April; this being a fairly plain grey above, with a grey-speckled breast and white belly. The juvenile and first-winter plumages, held by young birds from fledging until about one year old, are similar to the adult winter plumage but with the back feathers blacker with creamy white edging. In all plumages, the inner flanks and axillary feathers at the base of the underwing are black, a feature which readily distinguishes it from the other three Pluvialis species in flight. On the ground, it can also be told from the other Pluvialis species by its larger (24–34 mm, 0.94–1.34 in), heavier bill. (Source: Wikipedia.org, CC BY-SA)
The black-billed cuckoo (Coccyzus erythropthalmus) is a New World species in the Cuculidae (cuckoo) family. The scientific name is from Ancient Greek. The genus name, kokkuzo, means to call like a common cuckoo, and erythropthalmus is from eruthros, 'red' and ophthalmos, 'eye'. It is very similar and overlaps in range with the closely related yellow-billed cuckoo. A distinguishing characteristic of family Cuculidae is laying eggs in the nests of other birds. Although many cuckoos are obligate brood parasites, C. erythropthalmus often incubate their own chicks. (Source: Wikipedia.org, CC BY-SA)
The black-headed gull (Chroicocephalus ridibundus) is a small gull that breeds in much of the Palearctic including Europe and also in coastal eastern Canada. Most of the population is migratory and winters further south, but some birds reside in the milder westernmost areas of Europe. Small numbers also occur in northeastern North America, where it was formerly known as the common black-headed gull. As is the case with many gulls, it was previously placed in the genus Larus. The black-headed gull displays a variety of compelling behaviours and adaptations. Some of these include removing eggshells from one's nest after hatching, begging co-ordination between siblings, differences between sexes, conspecific brood parasitism, and extra-pair paternity. They are an overwintering species, found in a variety of different habitats. (Source: Wikipedia.org, CC BY-SA)
The blackpoll warbler (Setophaga striata) is a New World warbler. Breeding males are mostly black and white. They have a prominent black cap, white cheeks and white wing bars. The blackpoll breeds in forests of northern North America, from Alaska throughout most of Canada, to the mountains of New York and New England. They are a common migrant through much of North America. In fall, they fly south to the Greater Antilles and the northeastern coasts of South America in a non-stop long-distance migration over open water, averaging 2500 km, one of the longest distance non-stop overwater flights ever recorded for a migratory songbird. Rare vagrants to western Europe, they are one of the more frequent transatlantic passerine wanderers. (Source: Wikipedia.org, CC BY-SA)
The black-throated blue warbler (Setophaga caerulescens) is a small passerine bird of the New World warbler family. Its breeding ranges are located in the interior of deciduous and mixed coniferous forests in eastern North America. Over the cooler months, it migrates to islands in the Caribbean and Central America. It is very rarely found in western Europe, where it is considered to be a non-indigenous species. The black-throated blue warbler is sexually dimorphic; the adult male has a black face and cheeks, deep blue upperparts and white underparts, while the adult female is olive-brown above and light yellow below. (Source: Wikipedia.org, CC BY-SA)
The black-throated green warbler (Setophaga virens) is a small songbird of the New World warbler family. It has an olive-green crown, a yellow face with olive markings, a thin pointed bill, white wing bars, an olive-green back and pale underparts with black streaks on the flanks. Adult males have a black throat and upper breast; females have a pale throat and black markings on their breast. The breeding habitat of the black-throated green warbler is coniferous and mixed forests in eastern North America and western Canada and cypress swamps on the southern Atlantic coast. These birds' nests are open cups, which are usually situated close to the trunk of a tree. (Source: Wikipedia.org, CC BY-SA)
The Blackburnian warbler (Setophaga fusca) is a small New World warbler. They breed in eastern North America, from southern Canada, westwards to the southern Canadian Prairies, the Great Lakes region and New England, to North Carolina. Blackburnian warblers are migratory, wintering in southern Central America and in South America, and are very rare vagrants to western Europe. Blackburnian warblers are small passerines and average-sized wood-warblers. They measure around 11 to 13 cm (4.3 to 5.1 in) long, with a 20 to 22 cm (7.9 to 8.7 in) wingspan, and weigh 8 to 13 g (0.28 to 0.46 oz). The average mass of an adult bird is 9.7 g (0.34 oz), although is slightly higher in fall due to fat reserves, averaging 10.2–10.4 g (0.36–0.37 oz). Among standard measurements, the wing chord is 6.3 to 7.3 cm (2.5 to 2.9 in), the tail is 4.2 to 5 cm (1.7 to 2.0 in), the bill is 0.9 to 1 cm (0.35 to 0.39 in) and the tarsus is 1.6 to 1.8 cm (0.63 to 0.71 in). In summer, male Blackburnian warblers display dark gray backs and double white wing bars, with yellowish rumps and dark brown crowns. The underparts of these birds are white, and are tinged with yellow and streaked black. The head is strongly patterned in yellow and black, with a flaming-orange throat.

The blue crane (Grus paradisea), also known as the Stanley crane and the paradise crane, is the national bird of South Africa. The species is listed as Vulnerable by the IUCN. The blue crane is a tall, ground-dwelling bird, but is fairly small by the standards of the crane family. It is 100–120 cm (3 ft 3 in – 3 ft 11 in) tall, with a wingspan of 180–200 cm (5 ft 11 in – 6 ft 7 in) and weighs 3.6–6.2 kg (7.9–13.7 lb). Among standard measurements, the wing chord measures 51.4–59 cm (20.2–23.2 in), the exposed culmen measures 8–10 cm (3.1–3.9 in) and the tarsus measures 20.5–25.2 cm (8.1–9.9 in). This crane is pale blue-gray in color becoming darker on the upper head, neck and nape. From the crown to the lores, the plumage is distinctly lighter, sometimes whitish. The bill is ochre to greyish, with a pink tinge. The long wingtip feathers which trail to the ground. The primaries are black to slate grey, with dark coverts and blackish on the secondaries. Unlike most cranes, it has a relatively large head and a proportionately thin neck. Juveniles are similar but slightly lighter, with tawny coloration on the head, and no long wing plumes.

The blue grosbeak (Passerina caerulea), is a medium-sized North American passerine bird in the cardinal family Cardinalidae. It is mainly migratory, wintering in Central America and breeding in northern Mexico and the southern United States. The male is blue with two brown wing bars. The female is mainly brown with scattered blue feathers on the upperparts and two brown wing bars. The male blue grosbeak is deep blue, with both black and brown on its wings. The female is mostly brown. Both sexes are distinguished by their large, deep bill and double wing bars. These features, as well as the grosbeak's relatively larger size, distinguish this species from the indigo bunting. Length can range from 14 to 19 cm (5.5 to 7.5 in) and wingspan is from 26 to 29 cm (10 to 11 in). Body mass is typically from 26 to 31.5 g (0.92 to 1.11 oz). (Source: Wikipedia.org, CC BY-SA)
The blue jay (Cyanocitta cristata) is a passerine bird in the family Corvidae, native to eastern North America. It lives in most of the eastern and central United States; some eastern populations may be migratory. Resident populations are also in Newfoundland, Canada; breeding populations are found across southern Canada. It breeds in both deciduous and coniferous forests, and is common in residential areas. Its coloration is predominantly blue, with a white chest and underparts, and a blue crest; it has a black, U-shaped collar around its neck and a black border behind the crest. Males and females are similar in size and plumage, and plumage does not vary throughout the year. Four subspecies have been recognized. The blue jay feeds mainly on seeds and nuts, such as acorns, which it may hide to eat later; soft fruits; arthropods; and occasionally small vertebrates. It typically gleans food from trees, shrubs, and the ground, and sometimes hawks insects from the air. Blue jays can be very aggressive to other birds; they sometimes raid nests and have even been found to have decapitated other birds. (Source: Wikipedia.org, CC BY-SA)
Audubon's warbler (Setophaga auduboni) is a small bird of the family Parulidae. This passerine bird was long known to be closely related to its eastern counterpart, the myrtle warbler, and at various times the two forms have been classed as separate species or grouped as the yellow-rumped warbler, Setophaga coronata. The two forms probably diverged when the eastern and western populations were separated in the last ice age. In North America, the discovery of a hybrid zone between the two forms in western Canada led the American Ornithologists' Union in 1973 to recognize them as a single species. Audubon's warbler has a westerly distribution. It breeds in much of western Canada, the western United States, and into Mexico. It is migratory, wintering from the southern parts of the breeding range into western Central America. (Source: Wikipedia.org, CC BY-SA)
The blue-gray gnatcatcher or blue-grey gnatcatcher (Polioptila caerulea) is a very small songbird native to North America. These birds prefer humid areas with large leaves, woodlands, and more open sandy areas with sparse trees where they mainly eat insects, insect eggs, and spiders. The males often work to build nests, help incubate and raise the young, as well as feed the children, often thought to be a mother's role. Their nests are often built far out on a tree's branch with spider silks and lichen plants holding them together. They may hover over foliage while snatching prey (gleaning), or fly to catch insects in flight (hawking). The tail is often held upright while defending territory or searching for food.

The blue-winged teal (Spatula discors) is a species of bird in the duck, goose, and swan family Anatidae. One of the smaller members of the dabbling duck group, it occurs in North America, where it breeds from southern Alaska to Nova Scotia, and south to northern Texas. It winters along the Pacific and Atlantic coasts and south into the Caribbean islands and Central America. The blue-winged teal is 40 cm (16 in) long, with a wingspan of 58 cm (23 in), and a weight of 370 g (13 oz). The adult male has a greyish blue head with a white facial crescent, a light brown body with a white patch near the rear and a black tail. The adult female is mottled brown, and has a whitish area at base of bill. Both sexes have sky-blue wing coverts, a green speculum, and yellow legs. They have two molts per year and a third molt in their first year. The call of the male is a short whistle; the female's call is a soft quack. (Source: Wikipedia.org, CC BY-SA)
The yellow warbler (Setophaga petechia) is a New World warbler species. Yellow warblers are the most widespread species in the diverse genus Setophaga, breeding in almost the whole of North America, the Caribbean, and down to northern South America. Other than in male breeding plumage and body size, all warbler subspecies are very similar. Winter, female and immature birds all have similarly greenish-yellow uppersides and are a duller yellow below. Young males soon acquire breast and, where appropriate, head coloration. Females are somewhat duller, most notably on the head. In all, the remiges and rectrices are blackish olive with yellow edges, sometimes appearing as an indistinct wing-band on the former. The eyes and the short thin beak are dark, while the feet are lighter or darker olive-buff. (Source: Wikipedia.org, CC BY-SA)
The greenish warbler (Phylloscopus trochiloides) is a widespread leaf warbler with a breeding range in northeastern Europe, and temperate to subtropical continental Asia. This warbler is strongly migratory and winters in India. It is not uncommon as a spring or early autumn vagrant in Western Europe and is annually seen in Great Britain. In Central Europe large numbers of vagrant birds are encountered in some years; some of these may stay to breed, as a handful of pairs does each year in Germany. This is a typical leaf warbler in appearance, grayish-green above and off-white below. The single wing bar found in the southern and western populations distinguishes them from most similar species (except Arctic warbler P. borealis). It is slightly smaller than that species and has a thinner bill, without a dark tip to the lower mandible. A latitude-based analysis of wintering birds indicated that more northerly P. trochiloides are smaller, i.e. this species does not seem to follow Bergmann's rule. (Source: Wikipedia.org, CC BY-SA)
The blue-headed quail-dove (Starnoenas cyanocephala), or blue-headed partridge-dove, is a species of bird in the pigeon and dove family Columbidae. It is monotypic within the subfamily Starnoenadinae and genus Starnoenas. This bird has a mainly cinnamon-brown body with a bright blue crown, black eye stripe, white facial stripe, and a black gorget narrowly bordered with white markings and blue mottling on the sides. 30–33 cm in length. This species lives primarily on the forest floor where it forages for seeds, berries, and snails. It is generally found in pairs, though larger groups have been recorded with 18 birds found at a water hole in 1995. Breeding occurs mainly between April and June, with nests made on or close to the ground. (Source: Wikipedia.org, CC BY-SA)
The bluebirds are a North American group of medium-sized, mostly insectivorous or omnivorous birds in the order of Passerines in the genus Sialia of the thrush family (Turdidae). Bluebirds are one of the few thrush genera in the Americas. Bluebirds lay an average of 4 to 6 eggs. They will usually brude 2 times but maybe 3. Bluebirds nest from March all the way through August. Bluebirds have blue, or blue and rose beige, plumage. Female birds are less brightly colored than males, although color patterns are similar and there is no noticeable difference in size. Bluebirds are territorial and prefer open grassland with scattered trees. This is similar to the behavior of many species of woodpeckers. Bluebirds can typically produce between two and four broods during the spring and summer (March through August in the Northeastern United States). Males identify potential nest sites and try to attract prospective female mates to those nesting sites with special behaviors that include singing and flapping wings, and then placing some material in a nesting box or cavity. If the female accepts the male and the nesting site, she alone builds the nest and incubates the eggs. (Source: Wikipedia.org, CC BY-SA)
The boat-tailed grackle (Quiscalus major) is a passerine bird of the family Icteridae found as a permanent resident on the coasts of the Southeastern United States. The male boat-tailed grackle is 37–43 cm (15–17 in) long and weighs 165–250 g (5.8–8.8 oz). Adult males have entirely iridescent black plumage, a long dark bill, a pale yellowish or brown iris, and a long keel-shaped tail. The adult female is much smaller at 26–33 cm (10–13 in) long and a weight of 90–115 g (3.2–4.1 oz). She is also distinguished by her shorter tail and tawny-brown coloration, which covers the body apart from the darker wings and tail. The wingspan in adult birds is 39–50 cm (15–20 in). In standard measurements, this species measures 13–20 cm (5.1–7.9 in) along the wing bone, 11–20 cm (4.3–7.9 in) in tail length, 2–4.2 cm (0.79–1.65 in) along the culmen, and 3.6–5.8 cm (1.4–2.3 in) along the tarsus. On average, the boat-tailed grackle weighs about 10% more than the closely related great-tailed grackle, although the male great-tailed grackle has an even longer tail.

The Bohemian waxwing (Bombycilla garrulus) is a starling-sized passerine bird that breeds in the northern forests of the Palearctic and North America. It has mainly buff-grey plumage, black face markings and a pointed crest. Its wings are patterned with white and bright yellow, and some feather tips have the red waxy appearance that give this species its English name. The three subspecies show only minor differences in appearance. Females are similar to males, although young birds are less well-marked and have few or no waxy wingtips. Although the Bohemian waxwing's range overlaps those of the cedar and Japanese waxwings, it is easily distinguished from them by size and plumage differences. The breeding habitat is coniferous forests, usually near water. The pair build a lined cup-shaped nest in a tree or bush, often close to the trunk. The clutch of 3–7 eggs is incubated by the female alone for 13–14 days to hatching. The chicks are altricial and naked, and are fed by both parents, initially mostly with insects, but thereafter mainly fruit. They fledge about 14–16 days after leaving the egg. Many birds desert their nesting range in winter and migrate farther south. In some years, large numbers of Bohemian waxwings irrupt well beyond their normal winter range in search of the fruit that makes up most of their diet. (Source: Wikipedia.org, CC BY-SA)
The tyrant flycatchers (Tyrannidae) are a family of passerine birds which occur throughout North and South America. They are considered the largest family of birds known to exist in the world, with more than 400 species. They are the most diverse avian family in every country in the Americas, except for the United States and Canada. The members vary greatly in shape, patterns, size and colors. Some tyrant flycatchers may superficially resemble the Old World flycatchers, which they are named after but are not closely related to. They are members of suborder Tyranni (suboscines), which do not have the sophisticated vocal capabilities of most other songbirds. (Source: Wikipedia.org, CC BY-SA)
Bonaparte's gull (Chroicocephalus philadelphia) is a member of the gull family Laridae found mainly in northern North America. At 28 to 38 cm (11 to 15 in) in length, it is one of the smallest species of gull. Its plumage is mainly white with grey upperparts. During breeding season, Bonaparte's gull gains a slaty-black hood. The sexes are similar in appearance. Bonaparte's gull is among the smallest of the gull species; only little gull and Saunders's gull are smaller. Adults range from 28 to 38 cm (11 to 15 in) in length, with a wingspan of 76–84 cm (30–33 in) and a body mass of 180–225 g (6.3–7.9 oz). There is no difference in plumage or bare part colour between the sexes, though males tend to be heavier than females. Bonaparte's gull is smaller-bodied, smaller-headed, and smaller-billed than the other common hooded gulls of North America. The adult has grey upperparts and white underparts; its wingtips are black above and pale below. In breeding plumage, it has a slaty black hood, which it loses in non-breeding plumage. Its short, thin bill is black, and its legs are orangish-red. (Source: Wikipedia.org, CC BY-SA)
A booby is a seabird in the genus Sula, part of the family Sulidae. Boobies are closely related to the gannets (Morus), which were formerly included in Sula. Boobies hunt fish by diving from a height into the sea and pursuing their prey underwater. Facial air sacs under their skin cushion the impact with the water. Boobies are colonial breeders on islands and coasts. They normally lay one or more chalky-blue eggs on the ground or sometimes in a tree nest. Selective pressures, likely through competition for resource, have shaped the ecomorphology and foraging behaviours of the six species of boobies in the Pacific. (Source: Wikipedia.org, CC BY-SA)
The brant or brent goose (Branta bernicla) is a small goose of the genus Branta. There are three subspecies, all of which winter along temperate-zone sea-coasts and breed on the high-Arctic tundra. The brant goose was strictly coastal bird in winter, rarely leaving tidal estuaries, where it feeds on eelgrass (Zostera marina) and the seaweed, sea lettuce (Ulva). On the east coast of North America, the inclusion of sea lettuce is a recent change to their diet, brought about by a blight on eelgrass in 1931. This resulted in the near-extirpation of the brant. The few that survived changed their diet to include sea lettuce until the eelgrass eventually began to return. Brants have maintained this diet ever since as a survival strategy. A similar collapse in eelgrass in Ireland in the 1930s also negatively impacted the population. In recent decades, it has started using agricultural land a short distance inland, feeding extensively on grass and winter-sown cereals. (Source: Wikipedia.org, CC BY-SA)
The broad-winged hawk (Buteo platypterus) is a medium-sized hawk of the genus Buteo. During the summer, some subspecies are distributed over eastern North America, as far west as British Columbia and Texas; they then migrate south to winter in the Neotropics from Mexico south to southern Brazil. Other subspecies are all-year residents on Caribbean islands. As in most raptors, females are slightly larger than males. Broad-winged hawks' wings are relatively short and broad with a tapered, somewhat pointed appearance. The two types of coloration are a dark morph with fewer white areas and a light morph that is more pale overall. Although the broad-winged hawk's numbers are relatively stable, populations are declining in some parts of its breeding range because of forest fragmentation. (Source: Wikipedia.org, CC BY-SA)
The brown songlark (Cincloramphus cruralis), also Australian songlark, is a small passerine bird found throughout much of Australia. A member of the family Locustellidae, this species is notable for sexual size dimorphism, among the most pronounced in any bird. It is a moderate-sized bird of nondescript plumage; the female brownish above and paler below, the larger male a darker brown. The bird is found throughout Australia, except for parts of the far north and Tasmania. There are particularly dense populations in the southern parts of the country. It prefers open pastures and grassy scrub, and feeds on seeds and insects. The species is highly nomadic. Local numbers fluctuate depending on rainfall and the bird will often flee from drought-affected areas. (Source: Wikipedia.org, CC BY-SA)
The brown pelican (Pelecanus occidentalis) is a bird of the pelican family, Pelecanidae, one of three species found in the Americas and one of two that feed by diving into water. It is found on the Atlantic Coast from New Jersey to the mouth of the Amazon River, and along the Pacific Coast from British Columbia to northern Chile, including the Galapagos Islands. The nominate subspecies in its breeding plumage has a white head with a yellowish wash on the crown. The nape and neck are dark maroon–brown. The upper sides of the neck have white lines along the base of the gular pouch, and the lower fore neck has a pale yellowish patch. The male and female are similar, but the female is slightly smaller. The nonbreeding adult has a white head and neck. The pink skin around the eyes becomes dull and gray in the nonbreeding season. It lacks any red hue, and the pouch is strongly olivaceous ochre-tinged and the legs are olivaceous gray to blackish-gray. (Source: Wikipedia.org, CC BY-SA)
The brown-headed nuthatch (Sitta pusilla) is a small songbird endemic to pine forests throughout the Southeastern United States. Genetic analyses indicated low differentiation between northern and southern populations in Florida, but the study also found lower genetic diversity among south Florida populations that may be a result of the increased habitat fragmentation that was documented. The Bahama nuthatch was formerly considered a subspecies (S. p. insularis), has since been reclassified as its own separate species. Two recent studies assessing vocalizations in Bahama and continental nuthatch populations found important differences. One of the studies also demonstrated that continental and Bahama populations did not respond aggressively to calls of the other population. This type of call-response study is often used to help define cryptic species. The bird, like other nuthatches, possesses a sharp black nail-like beak, which it uses to pound open seeds. It is a frequent visitor to feeding stations and is highly fond of sunflower seeds and suet cakes. Bold and inquisitive, this bird is readily approachable by humans. (Source: Wikipedia.org, CC BY-SA)
The buff-breasted sandpiper (Calidris subruficollis) is a small shorebird. The species name subruficollis is from Latin subrufus, 'reddish' (from sub, 'somewhat', and rufus, 'rufous') and collis, '-necked/-throated' (from collum, 'neck'). It is a calidrid sandpiper. This species is brown above, and has a buff face and underparts in all plumages. It has a short bill and yellow legs. Males are larger than females. Juveniles resemble the adults, but may be paler on the rear underparts. It migrates mainly through central North America, and is uncommon on the coasts. It occurs as a regular wanderer to western Europe, and is not classed as rare in Great Britain or Ireland, where small flocks have occurred. Only the pectoral sandpiper is a more common American shorebird visitor to Europe. (Source: Wikipedia.org, CC BY-SA)
The bufflehead (Bucephala albeola) is a small sea duck of the genus Bucephala, the goldeneyes. This species was first described by Carl Linnaeus in his landmark 1758 10th edition of Systema Naturae as Anas albeola. The bufflehead ranges from 32–40 cm (13–16 in) long and weighs 270–550 g (9.5–19.4 oz), with the drakes larger than the females. Averaging 35.5 cm (14.0 in) and 370 g (13 oz), it rivals the green-winged teal as the smallest American duck. The bufflehead has a wingspan of 21.6 in (55 cm). Adult males are striking black and white, with iridescent green and purple heads and a large white patch behind the eye. Females are grey-toned with a smaller white patch behind the eye and a light underside. (Source: Wikipedia.org, CC BY-SA)
The glaucous gull (Larus hyperboreus) is a large gull, the second-largest gull in the world. It breeds in Arctic regions of the Northern Hemisphere and winters south to shores of the Holarctic. The genus name is from Latin larus, which appears to have referred to a gull or other large seabird. The specific name hyperboreus is Latin for 'northern' from the Ancient Greek Huperboreoi people from the far north 'Glaucous' is from Latin glaucus and denotes the grey colour of the gull. An older English name for this species is burgomaster. This gull is migratory, wintering from in the North Atlantic and North Pacific Oceans as far south as the British Isles and northernmost states of the United States, also on the Great Lakes. A few birds sometimes reach the southern USA and northern Mexico. (Source: Wikipedia.org, CC BY-SA)
A partridge is a medium-sized galliform bird in any of several genera, with a wide native distribution throughout parts of Europe, Asia and Africa. Several species have been introduced to the Americas. They are sometimes grouped in the Perdicinae subfamily of the Phasianidae (pheasants, quail, etc.). However, molecular research suggests that partridges are not a distinct taxon within the family Phasianidae, but that some species are closer to the pheasants, while others are closer to the junglefowl. Partridges are medium-sized game birds, (Also known as Ditch Chickens in the Mid-West), generally intermediate in size between the larger pheasants, smaller quail; they're ground-dwelling birds that feature variable plumage colouration across species, with most tending to grey and brown.

het proefexamen op deze website is niet gedetailleerd genoeg waardoor de kennis volgens mij niet voldoende getest wordt, ik heb op meer dan 5 websites een proefexamen gemaakt en deze is zeer slecht. Gebruik aub de gratis website die de overheid heeft voorzien https://www.mijnrijbewijsb.be/, je zal zien dat de examens hier in ieder geval op deze website in veel groter detail gaan. (ik heb hier niets gekocht, enkel het gratis proefexamen gedaan)
