Canadian Intermountain Joint Venture
The Canadian Intermountain Joint Venture (CIJV) is a partnership of "government agencies, Aboriginal groups, nongovernmental organizations, industry, universities and landowners" for the implementation of the North American Waterfowl Management Plan in the inter-mountain areas of south and central British Columbia in Canada, and the south-western mountain region of Alberta. Its region of operation includes "all the mountain national parks", with boundaries delineated by the border with the United States to the south, the eastern crest of the Rocky Mountains to the east, the crest of the Coast Mountains to the west, and the boreal forest to the north. It is adjacent to the Intermountain West Joint Venture to the south, the Pacific Coast Joint Venture to the west, and the Prairie Habitat Joint Venture to the east. Established in November 2003, it operates as part of the North American Bird Conservation Initiative. It also participates in the implementation of The Canadian Shore ...

North American Waterfowl Management Plan
The North American Waterfowl Management Plan (NAWMP) is an international plan to conserve waterfowl and migratory birds in North America. It was established in 1986 by Canada and the United States, and expanded to include Mexico in 1994. In the United States, it was authorized by the North American Wetlands Conservation Act of 1989 (P.L. 101-233), and is administered by the Fish and Wildlife Service, with USDA agencies participating as appropriate. Projects of this plan are "international in scope, but implemented at regional levels". History Critical to the populations of migratory birds, wetlands in Canada and the United States had disappeared as a result of development since the days of early European settlement in both countries. By 1985, at least 53 percent of wetlands in the contiguous United States and a minimum of 29 percent of wetlands in Canada had been destroyed. This led to plummeting populations of waterfowl, which reached "record lows" in 1985. In 1986, the Canadia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brewer's Sparrow
Brewer's sparrow (''Spizella breweri'') is a small, slim species of American sparrow in the family Passerellidae. This bird was named after the ornithologist Thomas Mayo Brewer. Description and systematics Adults have grey-brown backs and speckled brown crowns, both with dark streaks, and a pale eye-ring. Their wings are brown with light wing bars and the underparts are pale grey. Their bill is pale with a dark tip and they have a long notched tail. They are similar in appearance to the clay-colored sparrow (''S. pallida'') but do not have a pale stripe on the crown or grey neck patch.

Nature Conservation Organizations Based In Canada
Nature, in the broadest sense, is the physical world or universe. "Nature" can refer to the phenomena of the physical world, and also to life in general. The study of nature is a large, if not the only, part of science. Although humans are part of nature, human activity is often understood as a separate category from other natural phenomena. The word ''nature'' is borrowed from the Old French ''nature'' and is derived from the Latin word ''natura'', or "essential qualities, innate disposition", and in ancient times, literally meant "birth". In ancient philosophy, ''natura'' is mostly used as the Latin translation of the Greek word ''physis'' (φύσις), which originally related to the intrinsic characteristics of plants, animals, and other features of the world to develop of their own accord. The concept of nature as a whole, the physical universe, is one of several expansions of the original notion; it began with certain core applications of the word φύσις by pre-Socr ...

Yellow-breasted Chat
The yellow-breasted chat (''Icteria virens'') is a large songbird found in North America, and is the only member of the family Icteriidae. It was once a member of the New World warbler family, but in 2017, the American Ornithological Society moved it to its own family. Its placement is not definitively resolved. Taxonomy The yellow-breasted chat was formerly considered the largest member of the family New World warbler, Parulidae, but following taxonomic studies, it was moved to the Monotypic taxon, monotypic family Icteriidae. Although Icteriidae is a distinct family from the Icterid, New World blackbirds (Icterid, Icteridae), which have a very similar name, taxonomic studies support them as being the closest living relatives of one another, and in a 2019 study Carl Oliveros and colleagues actually classified the yellow-breasted chat as a member of Icteridae. In addition, the former grouping of the yellow-breasted chat as a warbler was not too far off, as Parulidae is now consi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Williamson's Sapsucker
Williamson's sapsucker (''Sphyrapicus thyroideus'') is a medium-sized woodpecker belonging to the genus '' Sphyrapicus'' ( sapsuckers). Habitat and range Breeding habitat is open forested areas with conifers, mainly ponderosa pine, douglas-fir, and grand fir. Subalpine fir and western larch may also be important components of good habitat for these birds. Partially migratory, they breed in western North America from northern Mexico as far north as British Columbia. They are permanent residents in some parts of their range; migrating birds form small flocks and may travel as far south as central Mexico. Description Adult males are iridescent black on their head, back, sides and tail. They have a white stripe behind the eye and a lower white stripe across each side of the head, a red chin and a bright yellow belly. They have black wings with large white patches. The female is completely different in appearance: mainly black, with a pale yellow breast, a brownish head with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
White-headed Woodpecker
The white-headed woodpecker (''Leuconotopicus albolarvatus'') is a non-migratory woodpecker that resides in pine forests of the mountains of western North America. Description It has a black body (approximately long) and white head. It has white primary feathers that form a crescent in flight. Males have a red spot at the back of the head. Distribution and habitat The range of the white-headed woodpecker stretches in the mountains from British Columbia through southern California. They form nests in dead trees or snags and reproduce once per year. Taxonomy Most of the range is occupied by the nominate subspecies. In the southern part of the range, ''L. a. gravirostris'', which has a longer bill - especially in males - and tail, is only found on mountaintops of the San Gabriel Mountains to San Diego County. Birds on Mount Pinos are somewhat intermediate. mtDNA cytochrome ''b'' and ATP synthase subunit 6 sequence data confirms this arrangement and also suggests that the Mount P ...

Swainson's Hawk
Swainson's hawk (''Buteo swainsoni'') is a large bird species in the Accipitriformes order. This species was named after William Swainson, a British naturalist. It is colloquially known as the grasshopper hawk or locust hawk, as it is very fond of Acrididae (locusts and grasshoppers) and will voraciously eat these insects whenever they are available. Their breeding habitat is prairie and dry grasslands in western North America. They build a stick nest in a tree or shrub or on a cliff edge. This species is a long-distance migrant, wintering in Argentina; it has been recorded as a vagrant in neighboring Chile, in the island countries of the Dominican Republic, and Trinidad and Tobago, and in Norway. This species or its immediate predecessor is the ancestor of the Galápagos hawk, as demonstrated by recent research. Then later diverged from the mainland birds perhaps 300,000 years ago, a very short time in evolution. Description Swainson's hawk is a raptor and a medium-sized mem ...

Sage Thrasher
The sage thrasher (''Oreoscoptes montanus'') is a medium-sized passerine bird from the family Mimidae, which also includes mockingbirds, tremblers, and New World catbirds. It is the only member of the genus ''Oreoscoptes''. This seems less close to the Caribbean thrashers, but rather to the mockingbirds instead (Hunt ''et al.'' 2001, Barber ''et al.'' 2004). Description ''Oreoscoptes montanus'' are pale grey-brown on the upperparts and white with dark streaks on the underparts. They have a slim straight relatively short bill, yellow eyes and a long tail, although not as long as that of other thrashers. Measurements: * Length: 7.9-9.1 in (20-23 cm) * Weight: 1.4-1.8 oz (40-50 g) * Wingspan: 12.6 in (32 cm) Breeding As its name suggests, this bird breeds in western North America, from southern Canada to northern Arizona and New Mexico. Its breeding habitat is in areas with dense stands of sagebrush and rarely in other shrubby areas. The female lays 4 or 5 eggs in ...

Prairie Falcon
The prairie falcon (''Falco mexicanus'') is a medium-large sized falcon of western North America. It is about the size of a peregrine falcon or a crow, with an average length of 40 cm (16 in), wingspan of approximately 1 meter (40 in), and average weight of 720 g (1.6 lb). As in all falcons, females are noticeably bigger than males. Though a separate species from the peregrine, the prairie falcon is basically an arid environment adaptation of the early peregrine falcon lineage, able to subsist on less food than the peregrine, and generally lighter in weight than a peregrine of similar wing span. Having evolved in a harsh desert environment with low prey density, the prairie falcon has developed into an aggressive and opportunistic hunter of a wide range of both mammal and bird prey. It will regularly take prey from the size of sparrows to approximately its own weight, and occasionally much larger. It is the only larger falcon native only to North America. ...

Lark Sparrow
The lark sparrow (''Chondestes grammacus'') is a fairly large New World sparrow. It is the only member of the genus ''Chondestes''. Distribution and habitat It breeds in southern Canada, much of the United States, and northern Mexico. It is much less common in the east, where its range is contracting. The populations in Mexico and adjacent states of the United States are resident, but other birds are migratory, wintering in the southern United States, Mexico and south to Guatemala. It is a very rare vagrant to western Europe, with two accepted records in Great Britain in 1981 and 1991. Description The lark sparrow is distinctive. Adults have a typically sparrow-like dark-streaked brown back, and white underparts except for a dark central spot. The cheeks and crown sides are chestnut, with white eyebrow and crown stripes. The dark tail's corners are also white. Young lark sparrows are duller, and the underparts are streaked. Measurements: * Length: 5.9-6.7 in (15-17 cm) * W ...

Grasshopper Sparrow
The grasshopper sparrow (''Ammodramus savannarum'') is a small New World sparrow. It belongs to the genus ''Ammodramus,'' which contains three species that inhabit grasslands and prairies. Although sometimes found in crop fields and they will readily colonize reclaimed grassland. In the core of their range, grasshopper sparrows are dependent upon large areas of grassland where they avoid trees and shrubs. They seek out heterogenous patches of prairie that contain clumps of dead grass or other vegetation where they conceal their nest, and also contain barer ground where they forage for insects (especially grasshoppers), spiders, and seeds. Grasshopper sparrows are unusual among New World sparrows in that they sing two distinct song types, the prevalence of which varies with nesting cycle. The primary male song, a high trill preceded by a stereotyped series of short chips, is reminiscent of the sounds of grasshoppers and is the origin of this species' name.
