- The song of the male Blackpoll Warbler is one of the highest-pitched of all birds.
- Part of the fall migratory route of the Blackpoll Warbler is over the Atlantic Ocean from the northeastern United States to Puerto Rico, the Lesser Antilles, or northern South America. This route averages 3,000 km (1,864 mi) over water, requiring a potentially nonstop flight of up to 88 hours. To accomplish this flight, the Blackpoll Warbler nearly doubles its body mass and takes advantage of a shift in prevailing wind direction to direct it to its destination.
- The oldest recorded Blackpoll Warbler was a male, and at least 8 years, 1 month old, when it was recaptured and rereleased during banding operations in Alaska.
Breeds in boreal coniferous forest (primarily spruce) and woodland, mixed coniferous-deciduous second growth, tall shrubs, and alder thickets; in migration and winter found in a variety of forest, woodland, scrub and brushy habitats.
Insects and spiders, fruit during migration.

Blackpoll Warbler populations are declining. In the U.S. alone, the species declined by over 6% per year between 1966 and 2014, resulting in a cumulative decline of 96%, according to the North American Breeding Bird Survey. Partners in Flight estimates a global breeding population of 60 million with 76% spending some part of the year in Canada, and 24% in the U.S. They rate a 9 out of 20 on the Continental Concern Score. The 2014 State of the Birds Report listed the Blackpoll Warbler as a Common Bird in Steep Decline.
