COSEWIC assessment and status report on the Tweedy’s Lewisia Lewisiopsis tweedyi in Canada (2014)
Tweedy’s Lewisia is a clump-forming perennial herb arising from a thick, fleshy, reddish taproot. The evergreen, fleshy leaves form a basal cluster, from which arise multiple stems, each bearing 2-5 showy salmon-coloured, yellowish-pink or white flowers. Tweedy’s Lewisia is a distinctive showy species that has long been grown as an ornamental but has a reputation for being difficult to keep alive and therefore of commercial interest only to alpin ...
COSEWIC Assessment and Status Report on the Audouin's Night-stalking Tiger Beetle Omus audouini in Canada (2014)
The Audouin's Night-stalking Tiger Beetle is a medium sized (14 – 18 mm), dull black, flightless beetle. A closely related species, the Greater Night-stalking Tiger Beetle, occurs in similar habitats, but the adults of both species are easily distinguished.
COSEWIC Assessment and Status Report on the Bocaccio Sebastes paucispinis in Canada (2014)
Bocaccio is one of at least 39 species of rockfish found in marine waters off British Columbia (BC). It is distinguished from other rockfish (Sebastes spp.) by its long upper jaw. There are two demographic clusters of Bocaccio, one centred on the west coast of British Columbia and another centred on central/southern California. However, genetic studies fail to find population differentiation along the Pacific coast. This report treats all the Boc ...
COSEWIC Assessment and Status Report on the Cutlip Minnow Exoglossum maxillingua in Canada (2014)
The Cutlip Minnow, Exoglossum maxillingua, is a stout-bodied minnow that reaches a maximum length of 160 mm. It has silvery sides with a greenish purple sheen, and is distinguished from all other members of the family Cyprinidae in North America by its unique tri-lobed lower jaw.
COSEWIC Assessment and Status Report on the Eastern Tiger Salamander Ambystoma tigrinum in Canada (2014)
Eastern Tiger Salamanders are robust mole salamanders and among the largest terrestrial salamanders in North America. Adults are primarily dark olive to grey or brown with lighter olive to yellow spots on the back and sides. The head is round when viewed from above, the eyes are relatively small, and the underside is dark with yellow blotches. The Eastern Tiger Salamander was recently recognized to be a separate species from other tiger salamande ...
COSEWIC Assessment and Status Report on the Giant Threespine Stickleback Gasterosteus aculeatus and the Unarmoured Threespine Stickleback Gasterosteus aculeatus in Canada (2014)
The Giant Threespine Stickleback has a mean adult standard length (SL) exceeding 75 mm, being almost twice the length of most other freshwater Threespine Stickleback. Although not unique, several other morphological features also set it apart from the "typical" freshwater form: it has a more streamlined shape; more gill rakers and robust body armour; and has an unusual colouration. The two confirmed populations of the Giant Threespine Stickleback ...
COSEWIC assessment and status report on the Grasshopper Sparrow pratensis subspecies Ammodramus savannarum pratensis in Canada (2014)
The Grasshopper Sparrow pratensis subspecies (hereafter Eastern Grasshopper Sparrow) is a small dull-coloured song bird of grassland habitats. It has a short tail, flat head and conical beige bill. Adults of both sexes have similar plumage, i.e. a plain buff-coloured throat and breast, buff, unmarked or faintly marked flanks, whitish below and mottled with rust above. Its summer diet is largely composed of grasshoppers and so the Eastern Grasshop ...
COSEWIC Assessment and Status Report on the Harlequin Duck Histrionicus histrionicus Eastern population in Canada (2014)
The Harlequin Duck is a small sea duck. Breeding males are striking in appearance with their slate blue colour highlighted by streaks of white, copper, and black. Females are brown, with a pale belly, plus three white spots on each side of their head.
COSEWIC Assessment and Status Report on the Little Brown Myotis Myotis lucifugus Northern Myotis Myotis septentrionalis Tri-colored Bat Perimyotis subflavus in Canada (2014)
All three bat species are small (average 7.4 g), brown-pelaged, insectivorous species of the Family Vespertilionidae. Little Brown Myotis (Myotis lucifugus) likely is the most common bat species in Canada and the most familiar of the three species to the public because they often use buildings as day-roosts and forage in areas where they are visible (e.g., over lakes, aound streetlights, etc.). Northern Myotis (M. septentrionalis</e
COSEWIC Assessment and Status Report on the North Atlantic Right Whale Eubalaena glacialis in Canada (2014)
North Atlantic Right Whales (Eubalaena glacialis) are large baleen whales that measure ˜14 m (± 0.15 SD) and weigh ˜30 mt (± 5.4 SD) at maximum size according to standard growth models fitted using necropsy and photogrammetry data. However, Right Whales can reach lengths up to 18 m. Females are ˜0.7 m longer than males when sexually mature. Right Whales appear stocky, with broad paddle-like flippers, a large head (˜1/4 of their body length) and n ...
COSEWIC Assessment and Status Report on the Oregon Branded Skipper Hesperia colorado oregonia in Canada (2014)
The Oregon Branded Skipper (Hesperia colorado oregonia) is a small butterfly-like insect (wingspan 25 - 37 mm) in the family Hesperiidae. The dorsal wing surfaces are an overall reddish-orange with broad, dark brown wing margins and orange angular spots. The ventral wing surfaces are greenish grey with a rich brown background to the hindwing. Sexes are similar.
COSEWIC Assessment and Status Report on the Piping Plover Charadrius melodus in Canada (2014)
The Piping Plover is a small shorebird that is found only in North America. It has a pale, sand-coloured back, short stout bill and orange legs. During the breeding season, it also has a single black band across the breast, another black band across the forehead between the eyes, and a distinctive black tip on the orange bill. There are two subspecies: the interior subspecies breeds on the Canadian prairies, the US Great Plains, and in the Great ...
COSEWIC Assessment and Status Report on the Plains Bison Bison bison bison and the Wood Bison Bison bison athabascae in Canada (2014)
The American bison is a member of the wild cattle family and is the largest land mammal in North America. The two recognized subspecies--Plains Bison (Bison bison bison) and Wood Bison (B. b. athabascae)--have distinct morphology, body shape, size, and pelage patterns. Phylogenetic divisions between them remain despite a massive translocation of Plains Bison into the remnant Wood Bison population during the 1920s, which has had
COSEWIC assessment and status report on the Rocky Mountain Tailed Frog Ascaphus montanus in Canada (2014)
Adult Rocky Mountain Tailed Frogs are small frogs with a large head, a vertical pupil, broad and flattened outer hind toes and no ear drum. They vary in colour from tan or brown to olive green or red, and there is often a distinct, dark-edged copper bar between the eyes. Males have a short, conical extension of the cloaca, the source of the name "tailed frog”, which is used for copulation. The tadpoles possess an oral disc modified into a sucker ...
COSEWIC assessment and status report on the Short-tailed Albatross Phoebastria albatrus in Canada (2014)
The Short-tailed Albatross is the largest North Pacific seabird and, like all albatrosses, is adapted for long-distance oceanic travel. The species was hunted for its feathers and came close to extinction in the 1940s as a result, but is now recovering because of careful management by Japanese biologists. Before the feather harvest, Short-tailed Albatrosses were common off the coasts of the eastern Pacific, but are now rare non-breeding visi ...
