The red-necked grebe (Podiceps grisegena) is a migratory aquatic bird found in the temperate regions of the northern hemisphere. Its wintering habitat is largely restricted to calm waters just beyond the waves around ocean coasts, although some birds may winter on large lakes. Grebes prefer shallow bodies of fresh water such as lakes, marshes or fish-ponds as breeding sites. The red-necked grebe is a nondescript dusky-grey bird in winter. During the breeding season, it acquires the distinctive red neck plumage, black cap and contrasting pale grey face from which its name was derived. It also has an elaborate courtship display and a variety of loud mating calls. Once paired, it builds a nest from water plants on top of floating vegetation in a shallow lake or bog.

The red-shouldered hawk (Buteo lineatus) is a medium-sized buteo. Its breeding range spans eastern North America and along the coast of California and northern to northeastern-central Mexico. It is a permanent resident throughout most of its range, though northern birds do migrate, mostly to central Mexico. The main conservation threat to the widespread species is deforestation. Males are 38 to 58 cm (15 to 23 in) long and weigh on average 550 g (1.21 lb). Females are slightly larger at 47 to 61 cm (19 to 24 in) in length and a mean weight of 700 g (1.5 lb). The wingspan can range from 90 to 127 cm (35 to 50 in). Adult birds can vary in mass from 460 to 930 g (1.01 to 2.05 lb). Among standard measurements, the wing bone is 28–35 cm (11–14 in) long, the tail is 16–24 cm (6.3–9.4 in) long and the tarsus is 7.5–9 cm (3.0–3.5 in). Adults have brownish heads, reddish chests, and pale bellies with reddish bars. Their tails, which are quite long by Buteo standards, are marked with narrow white bars.

The red-tailed hawk (Buteo jamaicensis) is a bird of prey that breeds throughout most of North America, from the interior of Alaska and northern Canada to as far south as Panama and the West Indies. It is one of the most common members within the genus of Buteo in North America or worldwide. The red-tailed hawk is one of three species colloquially known in the United States as the 'chickenhawk', though it rarely preys on standard-sized chickens. The bird is sometimes also referred to as the red-tail for short, when the meaning is clear in context. Red-tailed hawks can acclimate to all the biomes within their range, occurring on the edges of non-ideal habitats such as dense forests and sandy deserts. The red-tailed hawk occupies a wide range of habitats and altitudes, including deserts, grasslands (from small meadows to the treed fringes of more extensive prairies), coniferous and deciduous forests, agricultural fields, and urban areas. Its latitudinal limits fall around the tree line in the subarctic and it is absent from the high Arctic. Generally it favors varied habitats with open woodland, woodland edge and open terrain. It is legally protected in Canada, Mexico, and the United States by the Migratory Bird Treaty Act. (Source: Wikipedia.org, CC BY-SA)
The common ringed plover or ringed plover (Charadrius hiaticula) is a small plover that breeds in Arctic Eurasia. The genus name Charadrius is a Late Latin word for a yellowish bird mentioned in the fourth-century Vulgate. It derives from Ancient Greek kharadrios a bird found in ravines and river valleys (kharadra, 'ravine'). The specific hiaticula is Latin and has a similar meaning to the Greek term, coming from hiatus, 'cleft' and -cola, 'dweller' (colere, 'to dwell'). Adults are 17–19.5 cm (6.7–7.7 in) in length with a 35–41 cm (14–16 in) wingspan. They have a grey-brown back and wings, a white belly, and a white breast with one black neckband. They have a brown cap, a white forehead, a black mask around the eyes and a short orange and black bill. The legs are orange and only the outer two toes are slightly webbed, unlike the slightly smaller but otherwise very similar semipalmated plover, which has all three toes slightly webbed, and also a marginally narrower breast band; it was in former times included in the present species. Juvenile ringed plovers are duller than the adults in colour, with an often incomplete grey-brown breast band, a dark bill and dull yellowish-grey legs. This species differs from the smaller little ringed plover in leg colour, the head pattern, and the lack of an obvious yellow eye-ring. (Source: Wikipedia.org, CC BY-SA)
The ring-necked duck (Aythya collaris) is a diving duck from North America commonly found in freshwater ponds and lakes. The scientific name is derived from Greek aithuia, an unidentified seabird mentioned by authors including Hesychius and Aristotle, and Latin collaris, 'of the neck' from collum, 'neck'. The adult male is similar in color pattern to the Eurasian tufted duck, its relative. Males are a little bit bigger than the female. It has two white rings surrounding its gray bill, a shiny black angular head, black back, white line on the wings, a white breast and yellow eyes. The adult female has a grayish brown angular head and body with a dark brown back, a dark bill with a more subtle light band than the male, grayish-blue feet and brown eyes with white rings surrounding them. Females also make a noise like trrr. The cinnamon neck ring is usually difficult to observe, which is why the bird is sometimes referred to as a 'ringbill'. (Source: Wikipedia.org, CC BY-SA)
The rock ptarmigan (Lagopus muta) is a medium-sized game bird in the grouse family. It is known simply as the ptarmigan in the UK. It is the official bird for the Canadian territory of Nunavut, where it is known as the aqiggiq (ᐊᕿᒡᒋᖅ), and the official game bird for the province of Newfoundland and Labrador. In Japan, it is known as the raichō (雷鳥), which means 'thunder bird'. It is the official bird of Gifu, Nagano, and Toyama Prefectures and is a protected species nationwide. Unlike many arctic bird species, ptarmigan do not gain substantial mass to hibernate over winter. The rock ptarmigan is seasonally camouflaged; its feathers moult from white in winter to brown in spring or summer. The breeding male has greyish upper parts with white wings and under parts. In winter, its plumage becomes completely white except for the black outer tail feathers and eye line. It can be distinguished from the winter willow ptarmigan by habitat and markings—the rock ptarmigan prefers higher elevations and more barren habitat. It also has a slender bill and a black eye stripe, which is absent in the willow ptarmigan. (Source: Wikipedia.org, CC BY-SA)
The mountain plover (Charadrius montanus) is a medium-sized ground bird in the plover family (Charadriidae). It is misnamed, as it lives on level land. Unlike most plovers, it is usually not found near bodies of water or even on wet soil; it prefers dry habitat with short grass (usually due to grazing) and bare ground. The word plover came from a Latin word pluvia which means 'rain'. In Medieval England some migratory birds became known as plovers because they returned to their breeding grounds each spring with rain. In 1832 American naturalist John Kirk Townsend spotted a species of unknown bird near the Rocky Mountains, and assumed that all these birds live in mountains. The plover comes back each spring to its breeding grounds, and so the wrong name mountain plover was given to the species. The mountain plover is 8 to 9.5 inches (20 to 24 cm) long and weighs about 3.7 ounces (105 grams). Its wingspread is 17.5 to 19.5 inches (44.5 to 49.5 cm). The mountain plover's call consists of a low, variable whistle. Both sexes are of the same size. In appearance it is typical of Charadrius plovers, except that unlike most, it has no band across the breast. The upperparts are sandy brown and the underparts and face are whitish. There are black feathers on the forecrown and a black stripe from each eye to the bill (the stripe is brown and may be indistinct in winter); otherwise the plumage is plain. The mountain plover is much quieter than its relative the killdeer. Its calls are variable, often low-pitched trilled or gurgling whistles. In courtship it makes a sound much like a far-off cow mooing. (Source: Wikipedia.org, CC BY-SA)
The common yellowthroat (Geothlypis trichas) is a New World warbler. In the U.S. Midwest, it is also known as the yellow bandit. It is an abundant breeder in North America, ranging from southern Canada to central Mexico. The genus name Geothlypis is from Ancient Greek geo, 'ground', and thlupis, an unidentified small bird; thlypis is often used in the scientific names of New World warblers. The specific trichas is also from Greek; trikhas is a kind of thrush, the word being derived from trikhos, 'hair'. Common yellowthroats are small songbirds that have olive backs, wings and tails, yellow throats and chests, and white bellies. Adult males have black face masks which stretch from the sides of the neck across the eyes and forehead, which are bordered above with white or gray. Females are similar in appearance, but have paler underparts and lack the black mask. Immature birds are similar in appearance to the adult female. First-year males have a faint black mask which darkens completely by spring. (Source: Wikipedia.org, CC BY-SA)
The rose-breasted grosbeak (Pheucticus ludovicianus), colloquially called 'cut-throat' due to its coloration, is a large, seed-eating grosbeak in the cardinal family (Cardinalidae). It is primarily a foliage gleaner. Males have black heads, wings, backs, and tails, and a bright rose colored patch on their white breast. Males and females exhibit marked sexual dimorphism. Breeding habitat consists of cool-temperate open deciduous woods throughout much of eastern North America, with migration to tropical America in winter. Rose-breasted grosbeaks have an average maximum lifespan of 7.3 years in the wild, and up to 24 years in captivity. Death in the wild is generally due to collision with objects (buildings, cars, etc.) and predation, to eggs, nestlings and adults. (Source: Wikipedia.org, CC BY-SA)
The roseate spoonbill (Platalea ajaja) is a gregarious wading bird of the ibis and spoonbill family, Threskiornithidae. It is a resident breeder in both South and North America. The roseate spoonbill's pink colour is diet-derived, consisting of the carotenoid pigment canthaxanthin, like the American flamingo. Plume hunting in the eighteenth and nineteenth centuries almost drove the roseate spoonbill to extinction. However, in recent years, the range of the species has expanded. The roseate spoonbill is 71–86 cm (28–34 in) long, with a 120–133 cm (47–52 in) wingspan and a body mass of 1.2–1.8 kg (2.6–4.0 lb). The tarsus measures 9.7–12.4 cm (3.8–4.9 in), the culmen measures 14.5–18 cm (5.7–7.1 in) and the wing measures 32.3–37.5 cm (12.7–14.8 in) and thus the legs, bill, neck and spatulate bill all appear elongated. Adults have a bare greenish head ('golden buff' when breeding) and a white neck, back and breast (with a tuft of pink feathers in the center when breeding), and are otherwise a deep pink. The bill is grey. There is no significant sexual dimorphism. (Source: Wikipedia.org, CC BY-SA)
The roseate tern (Sterna dougallii) is a species of tern in the family Laridae. The genus name Sterna is derived from Old English 'stearn', 'tern', and the specific dougallii refers to Scottish physician and collector Dr Peter McDougall (1777–1814). 'Roseate' refers to the bird's pink breast in breeding plumage. This is a small-medium tern, 33–36 cm (13–14 in) long with a 67–76 cm (26–30 in) wingspan, which can be confused with the common tern, Arctic tern, and the larger, but similarly plumaged, Sandwich tern. The roseate tern's thin sharp bill is black, with a red base which develops through the breeding season, and is more extensive in the tropical and southern hemisphere races. It is shorter-winged and has faster wing beats than common or Arctic tern. The upper wings are pale grey and its under parts white, and this tern looks very pale in flight, like a small Sandwich tern, although the outermost primary flight feathers darken during the summer. The adults have very long, flexible tail streamers and orange-red legs. In summer, the underparts of adults take on the pinkish tinge which gives this bird its name. (Source: Wikipedia.org, CC BY-SA)
The rough-legged buzzard (Europe) or rough-legged hawk (North America)(Buteo lagopus) is a medium-large bird of prey. It is found in Arctic and Subarctic regions of North America, Europe, and Russia during the breeding season and migrates south for the winter. It was traditionally also known as the rough-legged falcon in such works as John James Audubon's The Birds of America. Nests are typically located on cliffs, bluffs or in trees. Clutch sizes are variable with food availability, but three to five eggs are usually laid. These hawks hunt over open land, feeding primarily on small mammals. Along with the kestrels, kites, and osprey, this is one of the few birds of prey to hover regularly. (Source: Wikipedia.org, CC BY-SA)
The ruby-crowned kinglet (Corthylio calendula) is a very small passerine bird found throughout North America. It is a member of the kinglet family. The bird has olive-green plumage with two white wing bars and a white eye-ring. Males have a red crown patch, which is usually concealed. The sexes are identical (apart from the crown), and juveniles are similar in plumage to adults. It is one of the smallest songbirds in North America. The ruby-crowned kinglet is not closely related to other kinglets, and is put in its own genus, Corthylio. Three subspecies are currently recognized. The kinglet is migratory, and its range extends from northwest Canada and Alaska south to Mexico. Its breeding habitat is spruce-fir forests in the northern and mountainous regions of the United States and Canada. The ruby-crowned kinglet builds a cup-shaped nest, which may be pensile or placed on a tree branch and is often hidden. It lays up to 12 eggs, and has the largest clutch of any North American passerine for its size. It is mainly insectivorous, but also eats fruits and seeds. (Source: Wikipedia.org, CC BY-SA)
The ruby-throated hummingbird (Archilochus colubris) is a species of hummingbird that generally spends the winter in Central America, Mexico, and Florida, and migrates to Canada and other parts of Eastern North America for the summer to breed. It is by far the most common hummingbird seen east of the Mississippi River in North America. This hummingbird is from 7 to 9 cm (2.8 to 3.5 in) long and has an 8 to 11 cm (3.1 to 4.3 in) wingspan. Weight can range from 2 to 6 g (0.071 to 0.212 oz), with males averaging 3.4 g (0.12 oz) against the slightly larger female which averages 3.8 g (0.13 oz). Adults are metallic green above and grayish white below, with near-black wings. Their bill, at up to 2 cm (0.79 in), is long, straight, and very slender. As in all hummingbirds, the toes and feet of this species are quite small, with a middle toe of around 0.6 cm (0.24 in) and a tarsus of approximately 0.4 cm (0.16 in). The ruby-throated hummingbird can only shuffle if it wants to move along a branch, though it can scratch its head and neck with its feet. (Source: Wikipedia.org, CC BY-SA)
The ruddy duck (Oxyura jamaicensis) is a duck from North America and one of the stiff-tailed ducks. The genus name is derived from Ancient Greek oxus, 'sharp', and oura, 'tail', and jamaicensis is 'from Jamaica'. These are small, compact ducks with stout, scoop-shaped bills, and long, stiff tails they often hold cocked upward. They have slightly peaked heads and fairly short, thick necks. Male ruddy ducks have blackish caps that contrast with bright white cheeks. In summer, they have rich chestnut bodies with bright blue bills. In winter, they are dull gray-brown above and paler below with dull gray bills. Females and first-year males are brownish, somewhat like winter males but with a blurry stripe across the pale cheek patch. In flight, ruddy ducks show solidly dark tops of the wings.

The rufous hummingbird (Selasphorus rufus) is a small hummingbird, about 8 cm (3.1 in) long with a long, straight and slender bill. These birds are known for their extraordinary flight skills, flying 2,000 mi (3,200 km) during their migratory transits. It is one of nine species in the genus Selasphorus. The adult male has a white breast, rufous face, flanks and tail and an iridescent orange-red throat patch or gorget. Some males have some green on back and/or crown. The female has green, white, some iridescent orange feathers in the center of the throat, and a dark tail with white tips and rufous base. The female is slightly larger than the male. Females and the rare green-backed males are extremely difficult to differentiate from Allen's hummingbird. The typical 'notched' shape of the second rectrix (R2) is considered an important field mark to distinguish the adult male rufous hummingbird from the adult male Allen's hummingbird. This is a typical-sized hummingbird, being a very small bird. It weighs 2–5 g (0.071–0.176 oz), measures 7–9 cm (2.8–3.5 in) long and spans 11 cm (4.3 in) across the wings.

The ruffed grouse (Bonasa umbellus) is a medium-sized grouse occurring in forests from the Appalachian Mountains across Canada to Alaska. It is the most widely distributed game bird in North America. It is non-migratory. It is the only species in the genus Bonasa. The ruffed grouse is sometimes incorrectly referred to as a 'partridge', an unrelated phasianid, and occasionally confused with the grey partridge, a bird of open areas rather than woodlands. The ruffed grouse is the state game bird of Pennsylvania, United States. The average life span of a ruffed grouse is one year, although some birds are thought to live for as long as eleven years. Ruffed grouse are polygynous, and males may mate with several females during the breeding season.[citation needed] (Source: Wikipedia.org, CC BY-SA)
The rusty blackbird (Euphagus carolinus) is a medium-sized New World blackbird, closely related to grackles ('rusty grackle' is an older name for the species). It is a bird that prefers wet forested areas, breeding in the boreal forest and muskeg across northern Canada, and migrating southeast to the United States during winter. Formerly abundant, the rusty blackbird has undergone one of the most rapid declines of any abundant bird species in North America in recent years, for reasons that are not well understood. Adults have a pointed bill and a pale yellow eye. They have black plumage with faint green and purple gloss; the female is greyer. 'Rusty' refers to the brownish winter plumage. They resemble the western member of the same genus, the Brewer's blackbird; however, Brewer's has a longer bill and the male's head is iridescent green. (Source: Wikipedia.org, CC BY-SA)
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)
The sanderling (Calidris alba) is a small wading bird. The name derives from Old English sand-yrðling, 'sand-ploughman'. The genus name is from Ancient Greek kalidris or skalidris, a term used by Aristotle for some grey-coloured waterside birds. The specific, alba, is Latin for 'white'. It is a circumpolar Arctic breeder, and is a long-distance migrant, wintering south to South America, South Europe, Africa, and Australia. It is highly gregarious in winter, sometimes forming large flocks on coastal mudflats or sandy beaches. This bird is similar in size to a dunlin, but stouter, with a thick bill. It shows a strong white wingbar in flight, and runs along the sandy beaches it prefers with a characteristic 'bicycling' action of its legs, stopping frequently to pick small food items. It eats small crabs and other small invertebrates. In spring, birds migrating north from South America consume large numbers of horseshoe crab eggs in the Delaware Bay area.

The Sandwich tern (Thalasseus sandvicensis) is a tern in the family Laridae. It is very closely related to the lesser crested tern (T. bengalensis), Chinese crested tern (T. bernsteini), Cabot's tern (T. acuflavidus), and elegant tern (T. elegans) and has been known to interbreed with the lesser crested. It breeds in the Palearctic from Europe to the Caspian Sea wintering to South Africa, India and Sri Lanka. The Sandwich tern is a medium-large tern with grey upperparts, white underparts, a yellow-tipped black bill and a shaggy black crest which becomes less extensive in winter with a white crown. Young birds bear grey and brown scalloped plumage on their backs and wings. It is a vocal bird. It nests in a ground scrape and lays one to three eggs. Like all Thalasseus terns, the Sandwich tern feeds by plunge diving for fish, usually in marine environments, and the offering of fish by the male to the female is part of the courtship display.

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. Many birds in other families are also commonly called 'finches'. These groups include the estrildid finches (Estrildidae) of the Old World tropics and Australia; some members of the Old World bunting family (Emberizidae) and the New World sparrow family (Passerellidae); and the Darwin's finches of the Galapagos islands, now considered members of the tanager family (Thraupidae).

The scarlet ibis (Eudocimus ruber) is a species of ibis in the bird family Threskiornithidae. It inhabits tropical South America and part of the Caribbean. In form, it resembles most of the other twenty-seven extant species of ibis, but its remarkably brilliant scarlet coloration makes it unmistakable. It is one of the two national birds of Trinidad and Tobago, and its Tupi–Guarani name, guará, is part of the name of several municipalities along the coast of Brazil. This medium-sized wader is a hardy, numerous, and prolific bird, and it has protected status around the world. Its IUCN status is Least Concern. The legitimacy of Eudocimus ruber as a biological classification, however, is in dispute. Traditional Linnaean taxonomy classifies it as a unique species, but some scientists have moved to reclassify it as a subspecies of a more general American ibis species, along with its close relative, the American white ibis (Eudocimus albus). (Source: Wikipedia.org, CC BY-SA)
The lesser scaup (Aythya affinis) is a small North American diving duck that migrates south as far as Central America in winter. It is colloquially known as the little bluebill or broadbill because of its distinctive blue bill. The origin of the name scaup may stem from the bird's preference for feeding on scalp—the Scottish word for clams, oysters, and mussels; however, some credit it to the female's discordant scaup call as the name's source. It is apparently a very close relative of the Holarctic greater scaup or 'bluebill' (A. marila), with which it forms a superspecies. The scientific name is derived from Ancient Greek aithuia an unidentified seabird mentioned by authors including Hesychius and Aristotle, and Latin, affinis 'related to', from its resemblance to the greater scaup.

Sandpipers are a large family, Scolopacidae, of waders. They include many species called sandpipers, as well as those called by names such as curlew and snipe. The majority of these species eat small invertebrates picked out of the mud or soil. Different lengths of bills enable different species to feed in the same habitat, particularly on the coast, without direct competition for food. Sandpipers have long bodies and legs, and narrow wings. Most species have a narrow bill, but otherwise the form and length are quite variable. They are small to medium-sized birds, measuring 12 to 66 cm (4.7–26.0 in) in length. The bills are sensitive, allowing the birds to feel the mud and sand as they probe for food. They generally have dull plumage, with cryptic brown, grey, or streaked patterns, although some display brighter colours during the breeding season. Most species nest in open areas, and defend their territories with aerial displays. The nest itself is a simple scrape in the ground, in which the bird typically lays three or four eggs. The young of most species are precocial. (Source: Wikipedia.org, CC BY-SA)
The limpkin (Aramus guarauna), also called carrao, courlan, and crying bird, is a large wading bird related to rails and cranes, and the only extant species in the family Aramidae. It is found mostly in wetlands in warm parts of the Americas, from Florida to northern Argentina. It feeds on molluscs, with the diet dominated by apple snails of the genus Pomacea. Its name derives from its seeming limp when it walks. This bird is easier to hear than see. Its common vocalization is a loud wild wail or scream with some rattling quality, represented as 'kwEEEeeer or klAAAar.' This call is most often given at night and at dawn and dusk. Other calls include 'wooden clicking', clucks, and in alarm, a 'piercing bihk, bihk...'. (Source: Wikipedia.org, CC BY-SA)
Screech owls are typical owls (Strigidae) belonging to the genus Megascops with 23 living species. For most of the 20th century, this genus was merged with the Old World scops owls in Otus, but nowadays it is again considered separately based on a range of behavioral, biogeographical, morphological, and DNA sequence data. Similar to other owls, the screech owl females are larger than the males of their species. They have a compact size and shape. They are small and agile, and about 7 to 10 inches tall and have a wingspan around 18 to 24 inches. They have prominent, wide-set feather tufts with bright yellow/green eyes. They have different brownish hues with whitish, patterned underside. This coloration helps them get camouflage against the tree bark. (Source: Wikipedia.org, CC BY-SA)
The seaside sparrow (Ammospiza maritima) is a species of American sparrow. Adults have brownish upperparts with gray on the crown and nape, and a grayish-buff-colored breast with dark streaks; they have a dark face with gray cheeks, a white throat, and a short, pointed tail. Birds show a small yellow streak just above the eye. A typical seaside sparrow lifespan in 8 to 9 years of maximum. The oldest record of seaside sparrow was an individual male which at least 10 years old, at he recaptured, measure out the age and re-released during the banding operations of South Carolina.

The hooded warbler (Setophaga citrina) is a New World warbler. It breeds in eastern North America and across the eastern United States and into southernmost Canada (Ontario). It is migratory, wintering in Central America and the West Indies. Hooded warblers are very rare vagrants to western Europe. Recent genetic research has suggested that the type species of Wilsonia (hooded warbler W. citrina) and of Setophaga (American redstart S. ruticilla) are closely related and should be merged into the same genus. As the name Setophaga (published in 1827) takes priority over Wilsonia (published in 1838), hooded warbler would then be transferred as Setophaga citrina. This change has been accepted by the North American Classification Committee of the American Ornithologists' Union, and the IOC World Bird List. The South American Classification Committee continues to list the bird in the genus Wilsonia. (Source: Wikipedia.org, CC BY-SA)
The semipalmated sandpiper (Calidris pusilla) is a very small shorebird. The genus name is from Ancient Greek kalidris or skalidris, a term used by Aristotle for some grey-coloured waterside birds. The specific pusilla is Latin for 'very small'. It is a small sandpiper, 13–15 cm (5.1-5.9 in) long and weighing around 20-32 g (0.7-1.1 oz). Wingspan ranges from 13.8-14.6 in (35-37 cm). Adults have black legs and a short, stout, straight dark bill. The body is dark grey-brown on top and white underneath. The head and neck are tinged light grey-brown. This bird can be difficult to distinguish from other similar tiny shorebirds, in particular the western sandpiper; these are known collectively as 'peeps' or 'stints'. (Source: Wikipedia.org, CC BY-SA)
The willet (Tringa semipalmata) is a large shorebird in the family Scolopacidae. It is a relatively large and robust sandpiper, and is the largest of the species called 'shanks' in the genus Tringa. Its closest relative is the lesser yellowlegs, a much smaller bird with a very different appearance apart from the fine, clear, and dense pattern of the neck, which both species show in breeding plumage. It breeds in North America and the West Indies and winters in southern North America, Central America, the West Indies and South America. (Source: Wikipedia.org, CC BY-SA)
The sharp-shinned hawk (Accipiter striatus), commonly known as a sharpie, is a small hawk, with males being the smallest hawks in the United States and Canada, but with the species averaging larger than some Neotropical species, such as the tiny hawk. The taxonomy is far from resolved, with some authorities considering the southern taxa to represent three separate species: white-breasted hawk (A. chionogaster), plain-breasted hawk (A. ventralis), and rufous-thighed hawk (A. erythronemius). The American Ornithological Society keeps all four variations conspecific. (Source: Wikipedia.org, CC BY-SA)
The saltmarsh sparrow (Ammospiza caudacuta) is a small New World sparrow found in salt marshes along the Atlantic coast of the United States. At one time, this bird and the Nelson's sparrow (Ammospiza nelsoni) were thought to be a single species, the sharp-tailed sparrow. Because of this, the species was briefly known as the 'saltmarsh sharp-tailed sparrow.' Saltmarsh sparrow numbers are declining due to habitat loss largely attributed to human activity. The saltmarsh sparrow measures 11–14 cm (4.3–5.5 in) in length, has a wingspan of 17.8–21 cm (7.0–8.3 in), and weighs 14–23.1 g (0.49–0.81 oz). Adults have brownish upperparts with a gray nape, white throat and belly, and pale orange breast and sides with brown streaking. The face is orange with gray cheeks, a gray median crown stripe, brown lateral crown stripes, and a brown eyeline. The tail feathers are short and sharply pointed. (Source: Wikipedia.org, CC BY-SA)
The sharp-tailed grouse (Tympanuchus phasianellus), also known as the sharptail or fire grouse, is a medium-sized prairie grouse. One of three species in the genus Tympanuchus, the sharp-tailed grouse is found throughout Alaska, much of Northern and Western Canada, and parts of the Western and Midwestern United States. The sharp-tailed grouse is the provincial bird of the Canadian province of Saskatchewan. Adults have a relatively short tail with the two central (deck) feathers being square-tipped and somewhat longer than their lighter, outer tail feathers giving the bird its distinctive name. The plumage is mottled dark and light browns against a white background, they are lighter on the underparts with a white belly uniformly covered in faint 'V'-shaped markings. These markings distinguish sharp-tailed grouse from lesser and greater prairie chickens which are heavily barred on their underparts. Adult males have a yellow comb over their eyes and a violet display patch on their neck. This display patch is another distinguishing characteristic from prairie chickens as male prairie chickens have yellow or orange colored air sacs. The female is smaller than the male and can be distinguished by the regular horizontal markings across the deck feathers as opposed to the irregular markings on the males deck feathers which run parallel to the feather shaft. Females also tend to have less obvious combs. (Source: Wikipedia.org, CC BY-SA)
The horned lark or shore lark (Eremophila alpestris) is a species of lark in the family Alaudidae found across the northern hemisphere. It is known as 'horned lark' in North America and 'shore lark' in Europe. Males defend territories from other males during breeding season and females will occasionally chase away intruding females. Courting involves the male singing to the female while flying above her in circles. He then will fold his wings in and dive towards the female, opening his wings just before reaching the ground. The nest site is selected in the early spring by only the female and is either a natural depression in the bare ground or she digs a cavity using her bill and feet. She will spend 2–4 days preparing the site before building her nest. She weaves fine grasses, cornstalks, small roots, and other plant material and lines it with down, fur, feathers, and occasionally lint. The nest is about 3-4 inches in diameter with the interior diameter about 2.5 in wide and 1.5 in deep. It has been noted that she often adds a “doorstep” of pebbles, corncobs, or dung on one side of the nest. It is speculated that this is used to cover the excavated dirt and hide her nest more.

The northern shoveler (/ˈʃʌvələr/; Spatula clypeata), known simply in Britain as the shoveler, is a common and widespread duck. It breeds in northern areas of Europe and across the Palearctic and across most of North America, wintering in southern Europe, the Indian subcontinent, Southeast Asia, Central, the Caribbean, and northern South America. It is a rare vagrant to Australia. In North America, it breeds along the southern edge of Hudson Bay and west of this body of water, and as far south as the Great Lakes west to Colorado, Nevada, and Oregon. This species is unmistakable in the northern hemisphere due to its large spatulate bill. The breeding drake has an iridescent dark green head, white breast and chestnut belly and flanks. In flight, pale blue forewing feathers are revealed, separated from the green speculum by a white border. In early fall the male will have a white crescent on each side of the face. In non-breeding (eclipse) plumage, the drake resembles the female. (Source: Wikipedia.org, CC BY-SA)
The marbled murrelet (Brachyramphus marmoratus) is a small seabird from the North Pacific. It is a member of the family Alcidae, which includes auklets, guillemots, murres and puffins. It nests in old-growth forests or on the ground at higher latitudes where trees cannot grow. The marbled murrelet has declined in number since humans began logging its nest trees in the latter half of the 19th century. The decline of the marbled murrelet and its association with old-growth forests, at least in the southern part of its range, have made it a flagship species in the forest preservation movement.

The Acadian flycatcher (Empidonax virescens) is a small insect-eating bird of the tyrant flycatcher family. Adults have olive upperparts, darker on the wings and tail, with whitish underparts; they have a white eye ring, white wing bars and a wide bill. The breast is washed with olive. The upper part of the bill is dark; the lower part is yellowish. This bird's song is an explosive peet-sa. The call is a soft peet. They also have a call similar to that of the northern flicker A unique two-note song described as 'ka-zeep', and its location in its preferred habitat, are two features that help to identify this species.

The smew (Mergellus albellus) is a species of duck and is the only living member of the genus Mergellus. Mergellus is a diminutive of Mergus and albellus is from Latin albus 'white'. This genus is closely related to Mergus and is sometimes included in it, though it might be closer to the goldeneyes (Bucephala). The smew has hybridized with the common goldeneye (B. clangula). The drake smew, with its 'cracked ice' or 'panda' appearance, is unmistakable, and looks very black-and-white in flight. The females and immature males are grey birds with chestnut foreheads and crowns, and can be confused at a distance with the ruddy duck; they are often known as 'redhead' smew. It has oval white wing-patches in flight. The smew's bill has a hooked tip and serrated edges, which help it catch fish when it dives for them. The smew is 38–44 cm (15–17 in) long, with a wingspan of 56–69 cm, and a weight 450–650 g. (Source: Wikipedia.org, CC BY-SA)
The dark-eyed junco (Junco hyemalis) is a species of junco, a group of small, grayish New World sparrows. This bird is common across much of temperate North America and in summer ranges far into the Arctic. It is a very variable species, much like the related fox sparrow (Passerella iliaca), and its systematics are still not completely untangled. (Source: Wikipedia.org, CC BY-SA)

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)
