The Common Redpoll (Carduelis flammea) is a species in the finch family. It breeds somewhat further south than the Arctic Redpoll, also in habitats with thickets or shrubs. Nominate C. f. flammea (Mealy Redpoll) breeds across the northern parts of North America and Eurasia. There is also an Icelandic subspecies, Icelandic Redpoll (C. f. islandica), and one that breeds in Greenland and Baffin Island called the Greenland Redpoll (C. f. rostrata). Together the Iceland and Greenland... less ↑

The Sharp-shinned Hawk (Accipiter striatus) is a small hawk. In fact, "sharp-shins" are the smallest to reside in USA and Canada, though some Neotropical species are smaller (notably the aptly named Tiny Hawk). The taxonomy is far from resolved, with some authorities considering the southern taxa three separate species: White-breasted Hawk (A. chionogaster), Plain-breasted Hawk (A. ventralis) and Rufous-thighed Hawk (A. erythronemius). See taxonomy for further on this. less ↑

Acer rubrum (Red Maple, also known as Swamp or Soft Maple), is one of the most common and widespread deciduous trees of eastern North America. It ranges from the Lake of the Woods on the border between Ontario and Minnesota, east to Newfoundland, south to near Miami, Florida, and southwest to east Texas. Many of its features, especially its leaves, are quite variable in form. At maturity it often attains a height of around 15 m (50 ft).... less ↑

The Red-winged Blackbird (Agelaius phoeniceus) is a passerine bird of the family Icteridae found in most of North and much of Central America. It breeds from Alaska and Newfoundland south to Florida, the Gulf of Mexico, Mexico and Guatemala, with isolated populations in western El Salvador, northwestern Honduras and northwestern Costa Rica. It may winter as far north as Pennsylvania and British Columbia, but northern populations are generally migratory, moving south to Mexico and the southern... less ↑

Agkistrodon contortrix is a species of venomous snake found in North America, a member of the Crotalinae (pit viper) subfamily. Common names for the species include Copperhead and moccasin. The behaviour of Agkistrodon contortrix may lead to accidental encounters with humans. Five subspecies are currently recognized, including the nominate subspecies described here. less ↑

The moose (North America) or Eurasian elk (Europe) (Alces alces) is the largest extant species in the deer family. Moose are distinguished by the palmate antlers of the males; other members of the family have antlers with a dendritic ("twig-like") configuration. Moose typically inhabit boreal and mixed deciduous forests of the Northern Hemisphere in temperate to subarctic climates. less ↑

The Pintail or Northern Pintail (Anas acuta) is a widely occurring duck which breeds in the northern areas of Europe, Asia and North America. It is strongly migratory and winters south of its breeding range to the equator. Unusually for a bird with such a large range, it has no geographical subspecies if the possibly conspecific Eaton's Pintail is considered to be a separate species. less ↑

The Northern Shoveler ( /ˈʃʌvələr/; Anas clypeata), Northern Shoveller in British English, sometimes known simply as the Shoveler, is a common and widespread duck. It breeds in northern areas of Europe and Asia and across most of North America, and 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,... less ↑

The Common Teal or Eurasian Teal (Anas crecca) is a common and widespread duck which breeds in temperate Eurasia and migrates south in winter. It is the Old World counterpart of the North American Green-winged Teal ( A. carolinensis), which was formerly (and sometimes is still) considered a subspecies of A. crecca. The Common Teal often simply called "the teal" due to being the only one of these small dabbling ducks in much of its range. less ↑

The Blue-winged Teal (Anas discors) is a small dabbling duck. Its placement in Anas is by no means certain; a member of the "blue-winged" group also including the shovelers, it may be better placed in Spatula. It is not a teal in the strict sense, and also does not seem closely related to the Garganey as was for some time believed. Indeed, its color pattern is strikingly reminiscent of the Australasian Shoveler. less ↑

The Mallard (Anas platyrhynchos), probably the best-known and most recognizable of all ducks, is a dabbling duck which breeds throughout the temperate and sub-tropical areas of North America, Europe, Asia, Africa, New Zealand (where it is currently the most common duck species), and Australia. It is strongly migratory in the northern parts of its breeding range, and winters farther south. For example, in North America it winters south to Mexico, but also regularly strays into Central... less ↑

The American Toad (Bufo americanus) is a common species of toad found throughout the eastern United States and Canada. It is divided into three subspecies—the Eastern American Toad (B. a. americanus), the Dwarf American Toad (B. a. charlesmithi), and the rare Hudson Bay Toad (B. a. copei). Newer taxonomies consider this species Anaxyrus americanus. less ↑

The Golden Eagle (Aquila chrysaetos) is one of the best known birds of prey in the Northern Hemisphere. Like all eagles, it belongs to the family Accipitridae. Once widespread across the Holarctic, it has disappeared from many of the more heavily populated areas. Despite being locally extinct or uncommon, the species is still fairly ubiquitous, being present in Eurasia, North America and parts of Africa. less ↑

The Great Egret (Ardea alba), also known as Great White Egret, Common Egret, Large Egret or Great White Heron, is a large, widely-distributed egret. Distributed across most of the tropical and warmer temperate regions of the world, in southern Europe it is rather localized. In North America it is more widely distributed, and it is ubiquitous across the Sun Belt of the United States and in the rainforests of South America. It is sometimes confused with... less ↑

The Great Blue Heron (Ardea herodias) is a large wading bird in the heron family Ardeidae, common near the shores of open water and in wetlands over most of North and Central America as well as the West Indies and the Galápagos Islands. It is a rare vagrant to Europe, with records from Spain, the Azores and England. An all-white Caribbean population was once known as a separate species, the Great White Heron. less ↑

The Ruddy Turnstone (Arenaria interpres) is a small wading bird, one of two species of turnstone in the genus Arenaria. It is now classified in the sandpiper family Scolopacidae but was formerly sometimes placed in the plover family Charadriidae. It is a highly migratory bird, breeding in northern parts of Eurasia and North America and flying south to winter on coastlines almost worldwide. It is the only species of turnstone in much of its range and... less ↑

The Short-eared Owl (Asio flammeus) is a species of typical owl (family Strigidae). Owls belonging to genus Asio are known as the eared owls, as they have tufts of feathers resembling mammalian ears. These "ear" tufts may or may not be visible. Asio flammeus will display its tufts when in a defensive pose. However, its very short tufts are usually not visible. The Short-eared Owl is found in open country and grasslands. The word flammeus is... less ↑

The Upland Sandpiper, Bartramia longicauda, is a large shorebird, closely related to the curlews (Thomas, 2004). Older names are the Upland Plover and Bartram's Sandpiper. It is the only member of the genus Bartramia. The genus name and the old common name Bartram's Sandpiper commemorate the American naturalist William Bartram. The name "Bartram's Sandpiper" was made popular by Alexander Wilson, who was taught ornithology and natural history illustration by Bartram. less ↑

The Northern Short-tailed Shrew (Blarina brevicauda) is the largest shrew in the genus Blarina, and occurs in the northeastern region of North America. It is a semifossorial, highly active and voracious insectivore and is present in a variety of habitats. It is notable in that it is one of the few venomous mammals. The specific epithet, brevicauda, is a combination of the Latin brevis and cauda, meaning "short tail". less ↑

The Brant Goose (Branta bernicla), a goose of the genus Branta, is known in North America as Brant, Brent Goose or Black Brant. The spelling "Brant" is the original one, with "Brent" being a later folk-etymological idea that it was derived from a classical Greek waterbird name brenthos. It is in fact onomatopoeic, derived from the guttural call note of the species. For the origin of the scientific name bernicla, see Barnacle Goose. less ↑

The Canada Goose (Branta canadensis) is a wild goose belonging to the genus Branta, which is native to Arctic and temperate regions of North America, having a black head and neck, white patches on the face, and a brownish-gray body. It is quite often called the Canadian Goose, but that name is not strictly correct, according to the American Ornithologists' Union. less ↑

The Cattle Egret (Bubulcus ibis) is a cosmopolitan species of heron (family Ardeidae) found in the tropics, subtropics and warm temperate zones. It is the only member of the monotypic genus Bubulcus, although some authorities regard its two subspecies as full species. Despite the similarities in plumage to the egrets of the genus Egretta, it is more closely related to the herons of Ardea. Originally native to parts of Asia, Africa and Europe, it has undergone... less ↑

The Red-tailed Hawk (Buteo jamaicensis) is a bird of prey, one of three species colloquially known in the United States as the "chickenhawk," though it rarely preys on chickens. It breeds throughout most of North America, from western Alaska and northern Canada to as far south as Panama and the West Indies, and is one of the most common buteos in North America. Red-tailed Hawks can acclimate to all the biomes within its range. There are... less ↑

The Green Heron (Butorides virescens) is a small heron of North and Central America. It was long considered conspecific with its sister species the Striated Heron (Butorides striata), and together they were called "Green-backed Heron". Birds of the nominate subspecies (no matter which taxonomic arrangement is preferred) are extremely rare vagrants to western Europe; individuals from the Pacific coast of North America may similarly stray as far as Hawaii. less ↑

The Dunlin, Calidris alpina, is a small wader, sometimes separated with the other "stints" in Erolia. It is a circumpolar breeder in Arctic or subarctic regions. Birds that breed in northern Europe and Asia are long-distance migrants, wintering south to Africa and southeast Asia. Birds that breed in Alaska and the Canadian Arctic migrate short distances to the Pacific and Atlantic coasts of North America, although those nesting in Northern Alaska overwinter in Asia. less ↑

The Stilt Sandpiper, Calidris himantopus or Micropalama himantopus, is a small shorebird; it bears some resemblance to the smaller calidrid sandpipers or "stints". DNA sequence information is incapable of determining whether it should be placed in Calidris or in the monotypic genus Micropalama (Thomas et al., 2004). It appears most closely allied with the Curlew Sandpiper, which is another aberrant species only tentatively placed in Calidris and could conceivably separated with it in Erolia. less ↑

The Pectoral Sandpiper, "Calidris" melanotos, is a small wader. It is sometimes separated with the "stint" sandpipers in Erolia. This may or may not represent a good monophyletic group, depending on the placement of the phylogenetically enigmatic Curlew Sandpiper ("C." ferruginea), the type species of Erolia. In any case, the genus name Ereunetes – formerly used for the Western Sandpiper ("C." mauri) and Semipalmated Sandpiper ("C." pusilla), which are also members of the stint clade –... less ↑

The Labrador Duck, Camptorhynchus labradorius, was a striking black and white eider-like sea duck that was never known to be common, and is believed to be the first bird to become extinct in North America after 1500. The last Labrador Duck is believed to have been seen at Elmira, New York on December 12, 1878; the last preserved specimen was shot in 1875 on Long Island. It was thought to breed in Labrador, although no nests... less ↑

The coyote (US: /kaɪˈoʊtiː/ or /ˈkaɪ.oʊt/, UK: /kɔɪˈjoʊteɪ/ or /kɔɪˈjoʊt/; Canis latrans), also known as the American jackal or the prairie wolf, is a species of canine found throughout North and Central America, ranging from Panama in the south, north through Mexico, the United States and Canada. It occurs as far north as Alaska and all but the northernmost portions of Canada. There are currently 19 recognized subspecies, with 16 in Canada, Mexico and the United States, and... less ↑

The Wilson's Warbler (Cardellina pusilla) is a small New World warbler. It is primarily greenish above and yellow below, with rounded wings and a long, slim tail. The male has a black crown patch which is greatly reduced or missing entirely 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. less ↑

The North American Beaver (Castor canadensis) is the only species of beaver in the Americas, native to North America and introduced to South America. In the United States and Canada, where no other species of beaver occurs, it is usually simply referred to as beaver. Its other vernacular names, including American beaver and Canadian beaver, distinguish this species from the one other extant beaver, Castor fiber, native to Eurasia. ("Canadian beaver" also refers to the subspecies... less ↑

The Turkey Vulture, Cathartes aura, is a bird found throughout most of the Americas. It also known in some North American regions as the Turkey Buzzard (or just "buzzard"), and in some areas of the Caribbean as the John Crow or Carrion Crow. One of three species in the genus Cathartes, in the family Cathartidae, the Turkey Vulture is the most widespread of the New World vultures, ranging from southern Canada to the southernmost tip of... less ↑

The Veery, Catharus fuscescens, is a small thrush species. It is occasionally called Willow Thrush or Wilson's Thrush. This species is 16-18 cm in length, and has the white-dark-white underwing pattern characteristic of Catharus thrushes. It is a member of a close-knit group of migrant species which also includes the cryptotaxa Gray-cheeked Thrush and Bicknell's Thrush (Winker & Pruett, 2006). less ↑

The Grey-cheeked Thrush, Catharus minimus, is a medium-sized thrush. This species is 15-17 cm in length, and has the white-dark-white underwing pattern characteristic of Catharus thrushes. It is a member of a close-knit group of migrant species together with the Veery and Bicknell's Thrush (Winker & Pruett, 2006); it forms a cryptic species pair with the latter. The Grey-cheeked Thrush is all but indistinguishable from Bicknell's Thrush except by its slightly larger size and different song.... less ↑

Oriental Staff Vine (Celastrus orbiculatus) is a woody vine native to East Asia of the Celastraceae family. It is also commonly called Oriental Bittersweet, Japanese Bittersweet or Asiatic Bittersweet. Oriental staff vine was introduced into North America in 1879, and is considered to be an invasive species in eastern North America. It closely resembles the native North American species, Celastrus scandens, with which it will readily hybridize. less ↑

The Piping Plover (Charadrius melodus) is a small sand-colored, sparrow-sized shorebird that nests and feeds along coastal sand and gravel beaches in North America. The adult has yellow-orange legs, a black band across the forehead from eye to eye, and a black ring around the neck. This chest band is usually thicker in males during the breeding season, and it's the only reliable way to tell the sexes apart. It is difficult to see when standing... less ↑

Chelidonium majus, commonly known as the greater celandine or tetterwort (in America, the latter refers to Sanguinaria canadensis), is the only species in the genus Chelidonium, family Papaveraceae. The lesser celandine is not closely related, but its family, the Ranunculaceae, is allied to the Papaveraceae (Order Ranunculales). The greater celandine is native to Europe and the Mediterranean basin. It is also widespread in North America, having been brought there by settlers as a herbal remedy for... less ↑

The Snow Goose (Chen caerulescens), also known as the Blue Goose, is a North American species of goose. Its name derives from the typically white plumage. The genus of this bird is disputed. The American Ornithologists' Union and BirdLife International place this species and the other "white" geese in the Chen genus, while other authorities place it in the more traditional "grey" goose genus Anser. less ↑
