The California condor (Gymnogyps californianus) is a New World vulture and the largest North American land bird. It became extinct in the wild in 1987 when all remaining wild individuals were captured, but has since been reintroduced to northern Arizona and southern Utah (including the Grand Canyon area and Zion National Park), the coastal mountains of California, and northern Baja California in Mexico. It is the only surviving member of the genus Gymnogyps, although four extinct members of the genus are also known. The species is listed by the International Union for the Conservation of Nature as Critically Endangered, and similarly considered Critically Imperiled by NatureServe. The plumage is black with patches of white on the underside of the wings; the head is largely bald, with skin color ranging from gray on young birds to yellow and bright orange on breeding adults. Its 3.0 m (9.8 ft) wingspan is the widest of any North American bird, and its weight of up to 12 kg (26 lb) nearly equals that of the trumpeter swan, the heaviest among native North American bird species. The condor is a scavenger and eats large amounts of carrion. It is one of the world's longest-living birds, with a lifespan of up to 60 years. (Source: Wikipedia.org, CC BY-SA)
The Canada goose (Branta canadensis), sometimes called Canadian goose, is a large wild goose with a black head and neck, white cheeks, white under its chin, and a brown body. It is native to the arctic and temperate regions of North America, and it is occasionally found during migration across the Atlantic in northern Europe. It has been introduced to the United Kingdom, Ireland, Finland, Sweden, Denmark, New Zealand, Japan, Chile, Argentina, and the Falkland Islands. Like most geese, the Canada goose is primarily herbivorous and normally migratory; often found on or close to fresh water, the Canada goose is also common in brackish marshes, estuaries, and lagoons.

The Canada jay (Perisoreus canadensis), also known as the gray jay, grey jay, camp robber, or whisky jack, is a passerine bird of the family Corvidae. It is found in boreal forests of North America north to the tree line, and in the Rocky Mountains subalpine zone south to New Mexico and Arizona. A fairly large songbird, the Canada jay has pale grey underparts, darker grey upperparts, and a grey-white head with a darker grey nape. It is one of three members of the genus Perisoreus, a genus more closely related to the magpie genus Cyanopica than to other birds known as jays. The Canada jay itself has nine recognized subspecies. Canada jays live year-round on permanent territories in coniferous forests, surviving in winter months on food cached throughout their territory in warmer periods. The birds form monogamous mating pairs, with pairs accompanied on their territories by a third juvenile from the previous season. (Source: Wikipedia.org, CC BY-SA)
The Canada warbler (Cardellina canadensis) is a small boreal songbird of the New World warbler family (Parulidae). It summers in Canada and northeastern United States and winters in northern South America. The Canada warbler is sometimes called the 'necklaced warbler', because of the band of dark streaks across its chest. The adults have minimal sexual dimorphism, although the male's 'necklace' is darker and more conspicuous and also has a longer tail. Adults are 12–15 cm (4.7–5.9 in) long, have a wingspan of 17–22 cm (6.7–8.7 in) and weigh 9–13 g (0.32–0.46 oz). The chest, throat and belly of the bird is yellow, and its back is dark grey. It has no wingbars or tail spots, but the underside of the tail is white. It has a yellow line in front of its eye in the direction of the beak, but the most striking facial feature is the white eyerings or 'spectacles'. Immature specimens have similar coloration as adults but duller and with less pronounced facial features. (Source: Wikipedia.org, CC BY-SA)
The tufted titmouse (Baeolophus bicolor) is a small songbird from North America, a species in the tit and chickadee family (Paridae). The black-crested titmouse, found from central and southern Texas southward, was included as a subspecies but now is considered a separate species, Baeolophus atricristatus. These small birds have a white front and grey upper body outlined with rust colored flanks. Other characteristics include their black foreheads and the tufted grey crest on their heads. In juveniles, the black forehead is greatly diminished such that they may be confused with the oak titmouse (although their ranges do not overlap). Males tend to be larger than females.

The canvasback (Aythya valisineria) is a species of diving duck, the largest found in North America. It ranges from 48–56 cm (19–22 in) in length and weighs 862–1,600 g (1.900–3.527 lb), with a wingspan of 79–89 cm (31–35 in). It is the largest species in the genus Aythya, being similar in size to a mallard but with a heavier and more compact build than it. 191 males wintering in western New York averaged 1,252 g (2.760 lb) and 54 females there averaged 1,154 g (2.544 lb). The canvasback has a distinctive wedge-shaped head and long graceful neck. The adult male (drake) has a black bill, a chestnut red head and neck, a black breast, a grayish back, black rump, and a blackish brown tail. The drake's sides, back, and belly are white with fine vermiculation resembling the weave of a canvas, which gave rise to the bird's common name. The bill is blackish and the legs and feet are bluish-gray. The iris is bright red in the spring, but duller in the winter. The adult female (hen) also has a black bill, a light brown head and neck, grading into a darker brown chest and foreback. The sides, flanks, and back are grayish brown. The bill is blackish and the legs and feet are bluish-gray. Its sloping profile distinguishes it from other ducks. (Source: Wikipedia.org, CC BY-SA)
Various Passeriformes (perching birds) are commonly referred to as warblers. They are not necessarily closely related to one another, but share some characteristics, such as being fairly small, vocal, and insectivorous. (Source: Wikipedia.org, CC BY-SA)
Cardinalidae (often referred to as the 'cardinal-grosbeaks' or simply the 'cardinals') is a family of New World-endemic passerine birds that consists of cardinals, grosbeaks, and buntings. It also includes several birds such as the tanager-like Piranga and the warbler-like Granatellus. As such, membership of this group is not easily defined by a single or even a set of physical characteristics, but instead by molecular work. In general they are medium to large songbirds with stout features, some with large heavy bills. Members of this group are beloved for their brilliant red, yellow, or blue plumages seen in many of the breeding males in this family. Most species are monogamous breeders that nest in open-cup nests, with many taking turn incubating the nest and taking care of their young. Most are arboreal species though the dickcissel is a ground-dwelling prairie bird. (Source: Wikipedia.org, CC BY-SA)
The Carolina parakeet (Conuropsis carolinensis), or Carolina conure, is an extinct species of small green neotropical parrot with a bright yellow head, reddish orange face and pale beak that was native to the Eastern, Midwest and Plains states of the United States. It was the only indigenous parrot within its range, as well as one of only three parrot species native to the United States (the others being the thick-billed parrot, now extirpated, and the green parakeet, still present in Texas; a fourth parrot species, the red-crowned amazon, is debated). It was called puzzi la née ('head of yellow') or pot pot chee by the Seminole and kelinky in Chickasaw. Though formerly prevalent within its range, the bird had become rare by the middle of the 19th century. The last confirmed sighting in the wild was of the ludovicianus subspecies in 1910. The last known specimen, a male named Incas, perished in captivity at the Cincinnati Zoo in 1918, and the species was declared extinct in 1939. (Source: Wikipedia.org, CC BY-SA)
The mourning dove (Zenaida macroura) is a member of the dove family, Columbidae. The bird is also known as the American mourning dove, the rain dove, and colloquially as the turtle dove, and it was once known as the Carolina pigeon and Carolina turtledove. It is one of the most abundant and widespread of all North American birds and a popular gamebird, with more than 20 million birds (up to 70 million in some years) shot annually in the U.S., both for sport and meat. Its ability to sustain its population under such pressure is due to its prolific breeding; in warm areas, one pair may raise up to six broods of two young each in a single year. The wings make an unusual whistling sound upon take-off and landing, a form of sonation. The bird is a strong flier, capable of speeds up to 88 km/h (55 mph). Mourning doves are light gray and brown and generally muted in color. Males and females are similar in appearance. The species is generally monogamous, with two squabs (young) per brood. Both parents incubate and care for the young. Mourning doves eat almost exclusively seeds, but the young are fed crop milk by their parents. (Source: Wikipedia.org, CC BY-SA)
The tits, chickadees, and titmice constitute the Paridae, a large family of small passerine birds which occur mainly in the Northern Hemisphere and Africa. Most were formerly classified in the genus Parus. Members of this family are commonly referred to as 'tits' throughout much of the English speaking world, but North American species are called either 'chickadees' (onomatopoeic, derived from their distinctive 'chick-a dee dee dee' alarm call) or 'titmice'. The name titmouse is recorded from the 14th century, composed of the Old English name for the bird, mase (Proto-Germanic *maison, Dutch mees, German Meise), and tit, denoting something small. The former spelling, 'titmose', was influenced by mouse in the 16th century. Emigrants to New Zealand presumably identified some of the superficially similar birds of the genus Petroica of the family Petroicidae, the Australian robins, as members of the tit family, giving them the title tomtit, although, in fact, they are not related. These birds are mainly small, stocky, woodland species with short, stout bills. Some have crests. They range in length from 10 to 22 cm (3.9 to 8.7 in). They are adaptable birds, with a mixed diet including seeds and insects. Many species live around human habitation and come readily to bird feeders for nuts or seed, and learn to take other foods.

Several unrelated groups of songbirds are called catbirds because of their wailing calls, which resemble a cat's meowing. The genus name Ailuroedus likewise is from the Greek for 'cat-singer' or 'cat-voiced'. (Source: Wikipedia.org, CC BY-SA)
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 cedar waxwing (Bombycilla cedrorum) is a member of the family Bombycillidae or waxwing family of passerine birds. It is a medium-sized, mostly brown, gray, and yellow. This bird is named for its wax-like wing tips. It is a native of North and Central America, breeding in open wooded areas in southern Canada and wintering in the southern half of the United States, Central America, and the far northwest of South America. Its diet includes cedar cones, fruit, holly berries, and insects. The cedar waxwing is listed as least concern on the IUCN Red List. Cedar waxwings are medium-sized birds approximately 6–7 in (15–18 cm) long and weighing roughly 30 g (1.1 oz). Wingspan ranges from 8.7 to 11.8 in (22-30 cm). They are smaller and browner than their close relative, the Bohemian waxwing (which breeds farther to the north and west). Their markings are a 'silky, shiny collection of brown, gray, and lemon-yellow, accented with a subdued crest, rakish black mask, and brilliant-red wax droplets on the wing feathers.' These droplets may be the same color as the madrone berries they are known to eat. (Source: Wikipedia.org, CC BY-SA)
The chestnut-sided warbler (Setophaga pensylvanica) is a New World warbler. They breed in eastern North America and in southern Canada westwards to the Canadian Prairies. They also breed in the Great Lakes region and in the eastern United States. This species is a moderately-sized New World warbler. Despite having very different plumage, it is thought to be closely related to the widespread yellow warbler. In total, this species measures from 10 to 14 cm (3.9 to 5.5 in) in length and spans 16 to 21 cm (6.3 to 8.3 in) across the wings. Body weight ranges from 8 to 13.1 g (0.28 to 0.46 oz). Among standard measurements, the wing chord is 5.7 to 6.8 cm (2.2 to 2.7 in), the tail is 4.2 to 5.8 cm (1.7 to 2.3 in), the bill is 0.9 to 1 cm (0.35 to 0.39 in) and the tarsus is 1.7 to 1.9 cm (0.67 to 0.75 in).

Wilson's warbler (Cardellina pusilla) is a small New World warbler. It is greenish above and yellow below, with rounded wings and a long, slim tail. The male has a black crown patch; depending on the subspecies, that mark is reduced or absent in the female. It breeds across Canada and south through the western United States, and winters from Mexico south through much of Central America. It is a very rare vagrant to western Europe. Wilson's warbler is a small passerine, ranging from 10 to 12 cm (3.9 to 4.7 in) in length, with a wingspan of 14–17 cm (5.5–6.7 in) and a mass of 5–10 g (0.18–0.35 oz). It has a plain green-brown back and yellow underparts. The male has a small black cap. Males of the western race C. p. chryseola are greener above and brighter than males of the eastern, nominate race. Individuals from Alaska and the west-central portion of the species' range average slightly larger than those found in eastern and Pacific coastal populations. Its song is a chattering series of loud descending notes. The call is a flat 'chuff'. (Source: Wikipedia.org, CC BY-SA)
The chipping sparrow (Spizella passerina) is a species of New World sparrow, a passerine bird in the family Passerellidae. It is widespread, fairly tame, and common across most of its North American range. There are two subspecies, the eastern chipping sparrow and the western chipping sparrow. This bird is a partial migrant with northerly populations flying southwards in the fall to overwinter in Mexico and the southern United States, and flying northward again in spring. It molts twice a year. In its breeding plumage it has orangish-rust upper parts, gray head and underparts and a distinctive reddish cap. In non-breeding plumage, the cap is brown and the facial markings are less distinct. The song is a trill and the bird has a piercing flight call that can be heard while it is migrating at night.

The chuck-will's-widow (Antrostomus carolinensis) is a nocturnal bird of the nightjar family Caprimulgidae. It is mostly found in the southeastern United States (with disjunct populations in Long Island, New York, Ontario, Canada and Cape Cod, Massachusetts) near swamps, rocky uplands, and pine woods. It migrates to the West Indies, Central America, and northwestern South America. The chuck-will's-widow has a short bill and a long tail typical of the nightjars. It has mottled brownish underparts, a buff throat, reddish-brown feathers lined with black, and brown and white patterning on head and chest. Males have patches of white on their outer tail feathers. It is the largest nightjar in North America. In length, it ranges from 28 to 33 cm (11 to 13 in). The wingspan can range from 58 to 66 cm (23 to 26 in). The body mass of the species is from 66 to 188 g (2.3 to 6.6 oz). Among standard measurements, the wing chord is 20.1 to 22.5 cm (7.9 to 8.9 in), the tail is 13 to 15.1 cm (5.1 to 5.9 in), the bill is 1.1 to 1.4 cm (0.43 to 0.55 in) and the tarsus is 1.5 to 1.9 cm (0.59 to 0.75 in).

The cliff swallow or American cliff swallow (Petrochelidon pyrrhonota) is a member of the passerine bird family Hirundinidae, the swallows and martins. The generic name Petrochelidon is derived from Ancient Greek petros meaning 'rock' and khelidon 'swallow', and the specific name pyrrhonota comes from purrhos meaning 'flame-coloured' and -notos '-backed'. Cliff swallows are extremely social songbirds that can be found in large nesting colonies reaching over 2,000 nests. They are frequently seen flying overhead in large flocks during migration, gracefully foraging over fields for flying insects or perching tightly together on a wire preening under the sun. Cliff swallows build gourd-shaped nests made from mud with small entrance holes. They build their nests tightly together, on top of one another, under bridges or alongside mountain cliffs. Living in large populations, these aerial insectivores use extensive vocalizations to communicate warnings or food availability to the other individuals. (Source: Wikipedia.org, CC BY-SA)
Sage-grouse are grouse belonging to the bird genus Centrocercus. The genus includes two species: the Gunnison grouse (Centrocercus minimus) and the greater sage-grouse (Centrocercus urophasianus). These birds are distributed throughout large portions of the north-central and Western United States, as well as the Canadian provinces of Alberta and Saskatchewan. The International Union for Conservation of Nature classified the C. minimus species as endangered in 2020 and C. urophasianus as near threatened in 2016. Sage grouse are also collectively known as 'sagehen,' 'sage grouse,' 'sage cock,' 'sage chicken,' or 'cock of the plains.' (Source: Wikipedia.org, CC BY-SA)
Steller's jay (Cyanocitta stelleri) is a bird native to western North America and the mountains of Central America, closely related to the blue jay found in eastern North America. It is also known as the long-crested jay, mountain jay, and pine jay. It is the only crested jay west of the Rocky Mountains. It is also sometimes colloquially called a 'blue jay' in the Pacific Northwest, but is distinct from the blue jay (C. cristata) of eastern North America. The species inhabits pine-oak and coniferous forests. Steller's jay is about 30–34 cm (12–13 in) long and weighs about 100–140 g (3.5–4.9 oz). Steller's jay shows a great deal of regional variation throughout its range. Blackish-brown-headed birds from the north gradually become bluer-headed farther south. The Steller's jay has a more slender bill and longer legs than the blue jay and, in northern populations, has a much more pronounced crest.: 69 It is also somewhat larger.

The chestnut-bellied hummingbird (Saucerottia castaneiventris) is a Near Threatened species of hummingbird in the 'emeralds', tribe Trochilini of subfamily Trochilinae. It is endemic to Colombia. The chestnut-bellied hummingbird is about 9 cm (3.5 in) long. Both sexes have a black bill with a red base to the mandible. The adult male has bronze-green upperparts and a chestnut tail. Its throat and upper breast are glittering green, the belly chestnut, and the undertail coverts chestnut with greenish edges. The female is similar but with a slightly paler belly and white bars near the end of some throat feathers. Immatures are similar to the female with rufous edges on the feathers of the neck and rump.

The common gull or sea mew (Larus canus) is a medium-sized gull that breeds in the Palearctic, northern Europe. The closely related short-billed gull is sometimes included in this species, which may be known collectively as 'mew gull'. Many common gulls migrate further south in winter. There are differing accounts as to how the species acquired its vernacular name (see Etymology section below). Adult common gulls are 40–46 cm (16–18 in) long, noticeably smaller than the herring gull and slightly smaller than the ring-billed gull. It is further distinguished from the ring-billed gull by its shorter, more tapered bill, which is a more greenish shade of yellow and is unmarked during the breeding season. The body is grey above and white below. The legs are yellow in breeding season, becoming duller in the winter. In winter, the head is streaked grey and the bill often has a poorly defined blackish band near the tip, which is sometimes sufficiently obvious to cause confusion with ring-billed gull.

The trumpeter swan (Cygnus buccinator) is a species of swan found in North America. The heaviest living bird native to North America, it is also the largest extant species of waterfowl, with a wingspan of 185 to 250 cm (6 ft 2 in to 8 ft 2 in). It is the American counterpart and a close relative of the whooper swan (Cygnus cygnus) of Eurasia, and even has been considered the same species by some authorities. By 1933, fewer than 70 wild trumpeters were known to exist, and extinction seemed imminent, until aerial surveys discovered a Pacific population of several thousand trumpeters around Alaska's Copper River. Careful reintroductions by wildlife agencies and the Trumpeter Swan Society gradually restored the North American wild population to over 46,000 birds by 2010. (Source: Wikipedia.org, CC BY-SA)
The common buzzard (Buteo buteo) is a medium-to-large bird of prey which has a large range. A member of the genus Buteo, it is a member of the family Accipitridae. The species lives in most of Europe and extends its breeding range across much of the Palearctic as far as northwestern China (Tian Shan), far western Siberia and northwestern Mongolia. Over much of its range, it is a year-round resident. However, buzzards from the colder parts of the Northern Hemisphere as well as those that breed in the eastern part of their range typically migrate south for the northern winter, many journeying as far as South Africa. The common buzzard is an opportunistic predator that can take a wide variety of prey, but it feeds mostly on small mammals, especially rodents such as voles. It typically hunts from a perch. Like most accipitrid birds of prey, it builds a nest, typically in trees in this species, and is a devoted parent to a relatively small brood of young. The common buzzard appears to be the most common diurnal raptor in Europe, as estimates of its total global population run well into the millions. (Source: Wikipedia.org, CC BY-SA)
The common gallinule (Gallinula galeata) is a bird in the family Rallidae. It was split from the common moorhen by the American Ornithologists' Union in July 2011. It lives around well-vegetated marshes, ponds, canals, and other wetlands in the Americas. The species is not found in the polar regions or many tropical rainforests. Elsewhere, the common gallinule is likely the most commonly seen rail species in much of North America, except for the American coot in some regions. This is a common breeding bird in marsh environments and well-vegetated lakes. Populations in areas where the waters freeze, such as southern Canada and the northern USA, will migrate to more temperate climes. This species will consume a wide variety of vegetable material and small aquatic creatures. It forages beside or in the water, sometimes upending in the water to feed. Its wide feet allow it to hop about on lily pads. It is often secretive, but can become tame in some areas. Despite loss of habitat in parts of its range, the common gallinule remains plentiful and widespread. (Source: Wikipedia.org, CC BY-SA)
The Connecticut warbler (Oporornis agilis) is a small songbird of the New World warbler family. These medium-sized warblers measure 13–15 cm (5.1–5.9 in) in length, with a 22–23 cm (8.7–9.1 in) wingspan. Connecticut warblers weigh 10 g (0.35 oz) when they fledge, attaining an average weight of around 15 g (0.53 oz) as adults. However, birds preparing for migration pack on more weigh to survive the strenuous journey and can weigh up to 25 g (0.88 oz). This species has light yellow underparts and olive upper-parts; they have a light eye ring, pink legs, a long tail, pale wing bars and a thin pointed bill. Males have a grey hood; female and immatures are more brown and have a whitish throat. (Source: Wikipedia.org, CC BY-SA)
Phalacrocoracidae is a family of approximately 40 species of aquatic birds commonly known as cormorants and shags. Several different classifications of the family have been proposed, but in 2021 the IOU (formerly the IOC) adopted a consensus taxonomy of seven genera. The great cormorant (Phalacrocorax carbo) and the common shag (Gulosus aristotelis) are the only two species of the family commonly encountered in Britain and Ireland and 'cormorant' and 'shag' appellations have been later assigned to different species in the family somewhat haphazardly. Cormorants and shags are medium-to-large birds, with body weight in the range of 0.35–5 kilograms (0.77–11.02 lb) and wing span of 60–100 centimetres (24–39 in). The majority of species have dark feathers. The bill is long, thin and hooked. Their feet have webbing between all four toes. All species are fish-eaters, catching the prey by diving from the surface. They are excellent divers, and under water they propel themselves with their feet with help from their wings; some cormorant species have been found to dive as deep as 45 metres (150 ft). They have relatively short wings due to their need for economical movement underwater, and consequently have among the highest flight costs of any flying bird. (Source: Wikipedia.org, CC BY-SA)
Cowbirds are birds belonging to the genus Molothrus in the family Icteridae. They are of New World origin, and are obligate brood parasites, laying their eggs in the nests of other species. The genus was introduced by English naturalist William John Swainson in 1832 with the brown-headed cowbird (Molothrus ater) as the type species. The genus name combines the Ancient Greek mōlos, meaning 'struggle' or 'battle', with thrōskō, meaning 'to sire' or 'to impregnate'. (Source: Wikipedia.org, CC BY-SA)
The great crested grebe (Podiceps cristatus) is a member of the grebe family of water birds noted for its elaborate mating display. The great crested grebe is the largest member of the grebe family found in the Old World, with some larger species residing in the Americas. They measure 46–51 cm (18–20 in) long with a 59–73 cm (23–29 in) wingspan and weigh 0.9 to 1.5 kg (2.0 to 3.3 lb). It is an excellent swimmer and diver, and pursues its fish prey underwater. The adults are unmistakable in summer with head and neck decorations. In winter, this is whiter than most grebes, with white above the eye, and a pink bill. The young are distinctive because their heads are striped black and white. They lose these markings when they become adults. (Source: Wikipedia.org, CC BY-SA)
The black-crested titmouse or Mexican titmouse (Baeolophus atricristatus), is a passerine bird in the tit family Paridae. Once considered a subspecies of the tufted titmouse (B. bicolor), it was recognized as a separate species in 2002. It is native to southern Texas, Oklahoma, and east-central Mexico. Vagrants have been seen as far north and east as St. Louis, Missouri. The bird is 5.5 to 6.0 in (14 to 15 cm) long, with rusty flanks, gray upperparts, and a whitish belly. The male has a long, dark black crest that is usually erect, while the female's crest is not as dark. It is common wherever trees grow, whether they are deciduous, heavy timber, or urban shade trees. Its call peter, peter, peter is similar to that of the tufted titmouse, but shorter. Its diet consists of berries, nuts, spiders, insects, and insect eggs. (Source: Wikipedia.org, CC BY-SA)
The kinglet calyptura (Calyptura cristata) is a small passerine bird. It is the only member of the genus Calyptura in the family Tyrannidae. It had traditionally been considered a member of the family Cotingidae. It is endemic to Atlantic forest in south-eastern Brazil. For a long time this species was feared to be extinct, as it went unrecorded during the 20th century until two birds were observed in Serra dos Órgãos on several days in October 1996. Since these sightings, there have not been any confirmed records, although at least one recent—but unconfirmed—record exists from near Ubatuba. Consequently, it is considered Critically Endangered by BirdLife International. (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 downy woodpecker (Dryobates pubescens) is a species of woodpecker, the smallest in North America. Length ranges from 14 to 18 cm (5.5 to 7.1 in). Downy woodpeckers primarily live in forested areas throughout the United States and Canada, with the exception of deserts in the southwest and the northern tundra. The bird nests in tree cavities and feeds primarily on insects, although it supplements its diet with seeds and berries. The downy woodpecker is very similar in appearance to the hairy woodpecker, although they are not closely related. The downy woodpecker is virtually identical in plumage pattern to the larger hairy woodpecker, but it can be distinguished from the hairy by the presence of black spots on its white tail feathers and the length of its bill. The downy woodpecker's bill is shorter than its head, whereas the hairy woodpecker's bill is approximately equal to head length. (Source: Wikipedia.org, CC BY-SA)
Albatrosses, of the biological family Diomedeidae, are large seabirds related to the procellariids, storm petrels, and diving petrels in the order Procellariiformes (the tubenoses). They range widely in the Southern Ocean and the North Pacific. They are absent from the North Atlantic, although fossil remains show they once occurred there and occasional vagrants are found. Albatrosses are among the largest of flying birds, and species of the genus Diomedea (great albatrosses) have the longest wingspans of any extant birds, reaching up to 3.7 m (12 ft). The albatrosses are usually regarded as falling into four genera, but disagreement exists over the number of species. (Source: Wikipedia.org, CC BY-SA)
The mottled duck (Anas fulvigula) or mottled mallard is a medium-sized species of dabbling duck. It is intermediate in appearance between the female mallard and the American black duck. It is closely related to those species, and is sometimes erroneously considered a subspecies of the former. Along the Gulf of Mexico coast, the mottled duck is one of the most frequently banded waterfowl. This is due in part to the fact that it is mostly non-migratory. Approximately one out of every 20 mottled ducks is banded, making it an extremely prized and sought after bird among hunters. (Source: Wikipedia.org, CC BY-SA)
The dusky grouse (Dendragapus obscurus) is a species of forest-dwelling grouse native to the Rocky Mountains in North America. It is closely related to the sooty grouse (Dendragapus fuliginosus), and the two were previously considered a single species, the blue grouse. Adults have a long square tail, gray at the end. Adult males are mainly dark with a purplish throat air sac surrounded by white, and a yellow to red wattle over the eye during display. Adult females are mottled brown with dark brown and white marks on the underparts. Their breeding habitat is the edges of conifer and mixed forests in mountainous regions of western North America, from southeastern Alaska and Yukon south to New Mexico. Their range is closely associated with that of various conifers. Their nest is a scrape on the ground concealed under a shrub or log. (Source: Wikipedia.org, CC BY-SA)
Audubon's shearwater (Puffinus lherminieri) is a common tropical seabird in the petrel family. Sometimes known as the dusky-backed shearwater, the specific epithet honours the French naturalist Félix Louis L'Herminier. Certain populations are known variously as Baillon's shearwater, tropical shearwater, Bannerman's shearwater, Mascarene shearwater and Persian shearwater; some of these are considered distinct species by various authors. If they are all placed in P. lherminieri, the North Atlantic little shearwater (otherwise often separated as P. baroli) is generally included here too. Thus, these small shearwaters form a cryptic species complex. (Source: Wikipedia.org, CC BY-SA)
The black-necked grebe or Aeared grebe (Podiceps nigricollis) is a member of the grebe family of water birds. It was described in 1831 by Christian Ludwig Brehm. There are currently three accepted subspecies, including the nominate subspecies. Its breeding plumage features a distinctive ochre-coloured plumage which extends behind its eye and over its ear coverts. The rest of the upper parts, including the head, neck, and breast, are coloured black to blackish brown. The flanks are tawny rufous to maroon-chestnut, and the abdomen is white. When in its non-breeding plumage, this bird has greyish-black upper parts, including the top of the head and a vertical stripe on the back of the neck. The flanks are also greyish-black. The rest of the body is a white or whitish colour. The juvenile has more brown in its darker areas. The subspecies californicus can be distinguished from the nominate by the former's usually longer bill. The other subspecies, P. n. gurneyi, can be differentiated by its greyer head and upper parts and by its smaller size. P. n. gurneyi can also be told apart by its lack of a non-breeding plumage. This species is present in parts of Africa, Eurasia, and the Americas. (Source: Wikipedia.org, CC BY-SA)
Eiders (/ˈaɪ.dər/) are large seaducks in the genus Somateria. The three extant species all breed in the cooler latitudes of the Northern Hemisphere. The down feathers of eider ducks, and some other ducks and geese, are used to fill pillows and quilts—they have given the name to the type of quilt known as an eiderdown.

É incrível a confusão existente entre os condutores, sobre a circulação no corredor do BUS... Sabemos que não podemos circular, mas é inevitável o seu uso se mudarmos de direcção. Mesmo assim muita gente não entende isto e reina uma completa confusão.
