Male Black-throated Green Warblers are prodigious singers, and have been documented repeating their songs hundreds of times over the course of an hour. Singing males sometimes take a break to chase and fight rivals; these battles can be followed by a flight by the victor around his territory.

Summary
Trend
Moderate Decrease
Confidence: Medium
Goal
Within Goal Range
In Canada, the Black-throated Green Warbler breeds from central Alberta to the east coast, mainly in the Boreal forest but also extending into the Acadian forest in the Maritimes and into southern Ontario. It winters from Mexico to northern South America, as well as the Caribbean. There are approximately 6.3 million individuals in Canada, representing 68% of the global population and a high degree of responsibility for Canada. The Canadian population of Black-throated Green Warbler has shown a moderate decrease relative to 1970. Confidence in this assessment is medium because the Breeding Bird Survey has limited coverage of the northern limits of the breeding range. In spite of this trend, the Black-throated Green Warbler remains within its goal range, though this will likely change soon if the current decline continues.
