The Palm Warbler is an abundant and widespread species throughout Canada's boreal forest east of the Rocky Mountains. The Breeding Bird Survey and the Maritimes, Quebec and Ontario Breeding Bird Atlases suggest that the population, and/or its distribution, has increased steadily since about 1970. There are currently few known threats to the species on either the breeding grounds or the wintering grounds. With an estimated 100% of the global breeding population, Canada's responsibility for this species is very high. This species has been identified as a priority for conservation and/or stewardship in one or more Bird Conservation Region Strategies in Canada.
The Palm Warbler's adaptability to drier habitats, often those created by forest clear-cutting operations, may have made it more abundant in these areas (Whittam 2015a). However, the species seems to be exceptionally prone to collision with tall, lighted towers and structures (Wilson 2013), leading to increased fatalities relative to other species. In southern Canada, the Palm Warbler nests locally in bogs. Bog habitat in Quebec has been declining due to the peat moss industry, agriculture, and hydro-electric projects (Desrochers et al. 1998). However, currently populations appear to be increasing and few major conservation concerns currently exist for this species.
Environment and Climate Change Canada and partners have developed Bird Conservation Region Strategies in each of Canada’s Bird Conservation Regions (BCRs). In these strategies, selected species are identified as priorities for one or more of the following reasons:
