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 ↑

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 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 American Bullfrog (Rana catesbeiana)), often simply known as the Bullfrog in Canada and the United States, is an aquatic frog, a member of the family Ranidae, or “true frogs”, native to much of North America. This is a frog of larger, permanent water bodies, swamps, ponds, lakes, where it is usually found along the water's edge. On rainy nights, bullfrogs along with many other amphibians, go overland and may be seen in numbers on country... less ↑

The Wood Frog (Rana sylvatica) has a broad distribution over North America, extending from the southern Appalachians to the boreal forest with several notable disjunct populations including lowland eastern North Carolina. The wood frog has garnered attention by biologists over the last century because of its freeze tolerance, relatively great degree of terrestrialism (for a Ranid), interesting habitat associations (peat bogs, vernal pools, uplands), and relatively long-range movements. The ecology and conservation of the wood frog less ↑

Maianthemum canadense (Canadian May-lily, Canada Mayflower, False Lily-of-the-valley, Canadian Lily-of-the-valley, Twoleaved Solomonseal; syn.

The Northern Waterthrush (Parkesia noveboracensis) is one of the larger New World warblers. It breeds in the northern part of North America in Canada, and in the northern United States, (in areas including Alaska). This bird is migratory, wintering in Central America, the West Indies, and Florida; also Venezuela, Colombia, and Ecuador. It is a very rare vagrant to western Europe; also other South American countries. less ↑

The Blue-winged Warbler, Vermivora cyanoptera, is a fairly common New World warbler, 11.5 cm long and weighing 8.5 g. It breeds in eastern North America in southern Ontario and the eastern USA. Its range is extending northwards, where it is replacing the very closely related Golden-winged Warbler, Vermivora chrysoptera. It was formerly called Vermivora pinus, but this name is invalid, as it was given after descriptions of this species and the Pine Warbler. 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 American mink (Neovison vison) is a semi-aquatic species of Mustelid native to North America, though human intervention has expanded its range to many parts of Europe and South America. Because of this, it is classed as Least Concern by the IUCN. Since the extinction of the sea mink, the American mink is the only extant member of the genus Neovison. The American mink is a carnivore which feeds on rodents, fish, crustaceans, frogs and birds.... less ↑

The Eastern tent caterpillar (Malacosoma americanum) is a univoltine, social species that forms communal nests in the branches of trees. It is sometimes confused with the gypsy moth, or the fall webworm and may be erroneously referred to as a bagworm which is the common name applied to unrelated caterpillars in the family Psychidae. The moths oviposit almost exclusively on trees in the plant family Rosaceae, particularly cherry (Prunus) and apple (Malus). The caterpillars are hairy... less ↑

The Common Whitetail or Long-tailed Skimmer (Libellula lydia) is a common dragonfly across much of North America, with a striking and unusual appearance. The male's chunky white body (about 5 cm long), combined with the brownish-black bands on its otherwise translucent wings, give it a checkered look. Females have a brown body and a different pattern of wing spots, closely resembling that of female Libellula pulchella, the Twelve-spotted Skimmer. Whitetail females can be distinguished by their smaller... less ↑

The Snow Bunting (Plectrophenax nivalis), sometimes colloquially called a snowflake, is a passerine bird in the bunting family Emberizidae. It is an arctic specialist, with a circumpolar Arctic breeding range throughout the northern hemisphere. There are small isolated populations on a few high mountain tops south of the Arctic region, including the Cairngorms in central Scotland and the Saint Elias Mountains on the southern Alaska-Yukon border, and also Cape Breton Highlands. less ↑

The Kousa Dogwood (Cornus kousa or Benthamidia kousa) is a small deciduous tree 8–12 m tall, native to eastern Asia. Like most dogwoods, it has opposite, simple leaves, which are 4–10 cm long. The tree is extremely showy when in bloom, but what appear to be four petaled white flowers are actually bracts spread open below the cluster of inconspicuous yellow-green flowers. The blossoms appear in late spring, weeks after the tree leafs out. The Kousa Dogwood... 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 Willet (Tringa semipalmata), formerly in the monotypic genus Catoptrophorus as Catoptrophorus semipalmatus, is a large shorebird in the sandpiper family. It is a good-sized and stout scolopacid, the largest of the shanks. 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. less ↑

The Little Gull, Hydrocoloeus minutus or Larus minutus, is a small gull which breeds in northern Europe and Asia. It also has small colonies in parts of southern Canada. It is migratory, wintering on coasts in western Europe, the Mediterranean and (in small numbers) the northeast USA; in recent years non-breeding birds have summered in western Europe in increasing numbers. As is the case with many gulls, it has traditionally been placed in the genus Larus.... less ↑

The Laughing Gull (Leucophaeus atricilla) is a medium-sized gull of North and South America. It breeds on the Atlantic coast of North America, the Caribbean, and northern South America. Northernmost populations migrate further south in winter, and this species occurs as a rare vagrant to western Europe. (There was an influx into North-west Europe in late October 2005 when at least 18, possibly as many as 35, individuals occurred on one day in the UK alone.)... less ↑

The Black-capped Chickadee (Poecile atricapillus) is a small, North American songbird, a passerine bird in the tit family Paridae. It is the state bird of both Maine and Massachusetts in the United States, and the provincial bird of New Brunswick in Canada. It is notable for its capacity to lower its body temperature during cold winter nights, its good spatial memory to relocate the caches where it stores food, and its boldness near humans (they can... less ↑

The Tennessee Warbler, Oreothlypis peregrina, is a New World warbler. It breeds from the Adirondack Mountains in New York through northern Vermont, New Hampshire, and Maine north and west throughout much of Canada. Also found breeding in northeast Minnesota and northern U.P. of Michigan. It is migratory, wintering in southern Central America and northern Colombia and Venezuela, with a few stragglers going as far south as Ecuador. It is a very rare vagrant to western Europe.... 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 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 smooth green snake (Opheodrys vernalis) is a nonvenomous North American colubrid. It is also referred to as the grass snake. It is a slender, "small medium" snake that measures 36–51 cm (14–20 in) as an adult. It gets its common name from its smooth dorsal scales, as opposed to the rough green snake. It is found in marshes, meadows, open woods, and along stream edges and is native to regions of Canada, Illinois, Virginia, Wyoming, New Mexico,... less ↑

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 forests in eastern North America. Over the cooler months, it migrates to islands in the Caribbean and Central America. It is a very rarely found in western Europe, where it is considered to be an non-indigenous species. The Black-throated Blue Warbler is sexually dimorphic; the adult male... less ↑
