, The oldest known specimen was a male found in Quebec in 1982 at least 8 years old, having been banded in 1975. Look for a forest patch with a mossy understory filled with ferns, shrubs, and rhododendrons. Show. It is one of the last warblers to arrive north in the spring, and one of the first to leave in the fall to return to its South American wintering grounds. The Canada Warbler inhabits shady forest undergrowth year round, making this species vulnerable to forest loss. In the males, the head is bluish with a black forehead and cheeks, which join with a band of well-defined black stripes that run across the breast. During migration, they flock with other birds including Wilson's Warblers, Tufted Titmice, American Redstarts, and other warblers. , The female lays four to five eggs and incubates for about 12 days.  In Canada the summer range extends from southeastern Yukon to Nova Scotia. Although female singing among the parulids has long been considered "idiosyncratic," singing by female Canada warblers is supported by observation of female singing in congener Wilson's warbler and the closely related hooded warbler. In both sexes, black stripes form a collar on the breast, although this collar is less defined in the females. This warbler received its name from its discovery in Canada, where the majority of its breeding range occurs. Breeding Bird Survey (BBS) data for Canada suggest that the species has declined by 4.5%/year between 1968 and 2007, which amounts to a loss of approximately 85% of the population during that period. The second was a first winter, probably female observed for five days in October 2006 in County Clare, Ireland.  The birds are at least seasonally monogamous. " Canada Warblers fly more than 3,000 miles from their wintering grounds in South America to their breeding grounds in the United States and Canada. Mode II, used at dawn, after pairing and when near another male, involves variable songs, sung rapidly with irregular rhythm and chippipng between songs. The nests are made up of root masses, hummocks, stumps, stream banks, mossy logs, and sometimes leaf litter and grass clumps. In the winter it prefers mid- and upper-elevation habitats.  This conclusion, however, is contradicted by the sexes' wintering at different elevations. , During the breeding season 82% of the population can be found in Canada and 18% in the United States. , The age at which the young leave the nest is not known. The bird did not respond to playback of its own song or a recording of a male. The Canada Warbler (Cardellina canadensis) has declined by 71% from 1970 to 2012, at a rate of 2.9% per year, and is listed as Threatened in Canada. This may be completed before the first migration. Its repertoire consisted of a repeated song of 12 to 13 notes as well as several shorter songs consisting of the first five or six notes of the longer song. Take some time to scan the understory for quick movements and listen for a sharp chip followed by a sweet warble. , Partners in Flight estimates a global population of 4 million, while the American Bird Conservancy estimates that 1.5 million individuals exist. The oldest recorded Canada Warbler was a male who was at least 8 years old when he was found in Quebec in … Sightings of pairs during migration in Panama have led to the conclusion that they are permanently monogamous. Predictor Importance for Canada Warbler (Wilsonia canadensis) Relative to All Species.  Because of its preference for low-height foraging in deciduous forests, it may be bounded at higher elevations as suitable habitat disappears and suffer competition from the black-throated blue warbler which prefers similar habitats. New World Warblers(Order: Passeriformes, Family:Parulidae). John James Audubon illustrates the Canada warbler in Birds of America (published, London 1827-38) as Plate 73 entitled "Bonaparte's Flycatching-Warbler—Muscicapa bonapartii." The chicks remain in the nest for about 10 days after hatching and are dependent on their parents for two to three weeks after they leave the nest. The Canada Warbler is one of the last warblers to arrive in the NWT in the spring and one of the first to leave in the fall. Minnesota Breeding Bird Distribution* The Canada Warbler is an inhabitant of Minnesota’s northern forests. Boxplots provide a quick visual of the distribution of the variable importance from the random forest models from all 147 species (black boxplot) and how each species fits into the overall distribution (cyan line). In Canada the summer range extends from southeastern Yukon to Nova Scotia. Roberts and other contributors described the species as relatively common in a number of … Their calls are low chup's. Range map information. The population objectives address the species' long-term decline, which was the reason for its designation as Threatened (COSEWIC 2008). The causes of declines in Canada Warbler populations are unclear. Canada Warblers have been found nesting in the southern NWT, from north of Fort Liard to Kakisa. It spends the majority of the nonbreeding season in northern Andean forests, which are among the most threatened in the world, having experienced a 90% loss due to agricultural expansion (cattle, coffee, coca) and fuel wood production. It also nests in the high Appalachians as far south as Georgia. Range map information. The oldest recorded Canada Warbler was a male who was at least 8 years old when he was found in Quebec in 1982. Habitat and Biology. The males, which have a bluish-grey tail and upper parts contrasting with a yellow throat and breast, are typically more brightly coloured than the females and immatures. Because of its wide distribution, all efforts to protect the Canada Warbler must cross borders.  It employs several foraging tactics, such as flushing insects from foliage and catching them on the wing (which it does more frequently than other warblers), and searching upon the ground among fallen leaves. info) of this bird is loud and highly variable, resembling chip chewy sweet dichetty. During the breeding season the bird "nests in riparian thickets, brushy ravines, forest bogs, etc. They also respond strongly to pishing or squeaking sounds, peeking out of dense vegetation or coming in closer.  In the southern part of the breeding range, nest parasitism by cowbirds is frequent. The Canada Warbler is a small, brightly coloured songbird 12 to 15 cm in length. , At least 60–65% of the population nests in boreal forests in Canada, the Great Lakes region of the United States, New England and through the Appalachians. Canada Warblers can be a little more difficult to find than other warblers due to their declining populations and northern breeding distribution, but they are not impossible to find. Roberts described the species’ summer distribution as stretching as far south as northeastern Pine and southern Mille Lacs Counties and as far west as Itasca State Park and Lake of the Woods County. Look for a forest patch with a mossy understory filled with ferns, shrubs, and rhododendrons.
