The Canada Warbler (Wilsonia canadensis) is an uncommon, neotropical migrant, forest songbird that is locally distributed in the Boreal Plains and Taiga Plains ecoprovinces of northeastern British Columbia. Its habitat is deciduous forest (trembling aspen and birches) and deciduous-dominated mixedwoods with rich shrub and ground layers, often with considerable amounts of natural disturbance and uneven canopy layers. Habitat use in British Columbia also includes edges along mature deciduous stands, a habitat not generally reported in other regions. Very few data exist on populations in British Columbia, and those that do exist are small and localized in area. There are two short-term threats to populations: (1) logging of aspen forests for pulpwood and brush control, and (2) increased exposure to cowbird parasitism and predation through general fragmentation of habitat. However, logged blocks may regenerate to a suitable stage more rapidly than for other warbler species of concern. Much of its habitat is on we
