The Palm Warbler is a common and widespread species throughout Canada's Boreal forest east of the Rocky Mountains. It winters along the Pacific Coast and southeastern United States, as well as in Central America and the Caribbean. There are approximately 13 million individuals in Canada, which is nearly 100% of the global population and represents a very high degree of responsibility for Canada, as fewer than 60,000 others breed in the United States, in Minnesota, Wisconsin, Michigan, and New York. The Canadian population of Palm Warbler has shown a moderate increase relative to 1970 based on the Breeding Bird Survey, and more recent trends from multiple Canadian Migration Monitoring Network observatories all reflect at least a moderate rate of population growth. Confidence in the assessment is therefore high because of the alignment between these sources, despite the Breeding Bird Survey having limited coverage of the northern parts of the breeding range. The national population of Palm Warbler is within its goal range.
