Geographic Range [top]

Range Description:	Contopus cooperi breeds across Canada (overlapping into eastern USA) and Alaska, and down the west coast of the USA as far as northern Mexico. There are also isolated populations in several states in the eastern USA (Altman and Sallabanks 2000). It winters primarily in Panama and the Andes Mountains, from north and west Venezuela south through Ecuador to south-east Peru and west Bolivia (Altman and Sallabanks 2000). Casual wintering also occurs in the Guianas, Trinidad, south Venezuela, Brazil and south Peru (Altman and Sallabanks 2000). Based on data from the Breeding Bird Survey the population has declined by 3.5% annually since 1980, equating to a 30% decline over a ten year period, but a 20.6% decline for the period 1993-2002. Given the apparent benefits to the species of some forest management practices in north America, populations may be being affected by loss or alteration of habitat in their wintering grounds.

Population [top]

Population:	Rich et al. (2004).
Population Trend:	Decreasing

Habitat and Ecology [top]

Habitat and Ecology:	It breeds along forest edges and openings, semi-open forest, water edges and harvested forest where some structure has been retained. Prominent trees serve as singing and foraging posts, and both sexes are aggressively territorial (Altman and Sallabanks 2000).
Systems:	Terrestrial; Freshwater

Threats [top]

Major Threat(s):	Habitat loss and alteration of forest management practices may limit breeding success (Altman 1997). However, numerous studies suggest that several types of harvested forest are beneficial to the species (possibly recreating preferred post-forest fire habitat mosaics) (Altman and Sallabanks 2000). Unknown threats may be affecting the species on its wintering grounds.
