The Yellow Warbler breeds in nearly every corner of Canada except the far north, and its sweet song is among the most predominant sounds of spring in wet habitats. Its uniform yellow attire is dashed with rusty red streaks in adult males and to a lesser degree in some older females.

The Yellow Warbler breeds in willows, shrubby thickets, and wood edges, with a preference for riparian areas. It has an extensive breeding range that reaches across Canada from the Pacific coast and Yukon to Newfoundland and Labrador; the species winters from Mexico to northern South America. There are approximately 53 million individuals in Canada, which represents 54% of the global population and a high degree of responsibility for Canada. An additional 15 million individuals breed in Alaska and migrate through Canada, boosting the proportion of the global population that occurs in Canada to 70%. The Canadian population of Yellow Warbler has shown little change relative to 1970 based on the Breeding Bird Survey, although it is approaching the threshold of a moderate decrease. Confidence is medium because the northern portions of the breeding range are poorly sampled. The national population of Yellow Warbler is within its goal range.

The best source of information on the population status of Yellow Warbler in Canada is the Breeding Bird Survey (BBS). Although the northernmost portion of its range is poorly covered, precision is high and overall reliability of the BBS is considered medium. The national trend shows a largely stable to increasing trend from the early 1970s to late 1990s, but then a fairly steep decline ever since. The population is currently 23% below 1970 levels, and far enough below its long-term average to just barely remain within its goal range. Regional trends already show long-term decreases of 30 to 56% throughout most of British Columbia, the northwestern Boreal forest, central Ontario and Quebec, and the Maritimes. The only contrary trends are little change in southern Ontario and Quebec, and a moderate increase in the southern Prairies.
The goal for Yellow Warbler is to remain at or above its average population level from 1970 to 2022, based on the Breeding Bird Survey. Recent data show that the population is within its goal range.

The Yellow Warbler breeds in nearly every corner of Canada except the far north, and its sweet song is among the most predominant sounds of spring in wet habitats. Its uniform yellow attire is dashed with rusty red streaks in adult males and to a lesser degree in some older females.
Yellow Warbler is primarily reported between May and September in Canada, as it migrates south in the nonbreeding season.
