Cool Facts

  • No other North American warbler has an orange throat.
  • The Blackburnian Warbler is territorial on its breeding grounds and solitary in the winter. It forms flocks only during migration.
  • Although the Blackburnian Warbler does not associate with other birds while it is nesting, it will join foraging flocks of chickadees, kinglets, and nuthatches after the young fledge. The warbler will follow the mixed flock with its begging young. The begging of the warbler chicks can even attract chickadees.
  • The oldest recorded Blackburnian Warbler was a male, and at least 8 years, 2 months old, when it was recaptured and rereleased during banding operations in Minnesota.



  • Breeds in mature coniferous and mixed coniferous/deciduous forests.
  • Winters in montane forests.

Least Concern

Blackburnian Warbler populations are stable. Partners in Flight estimates a global breeding population of 10 million birds with 28% spending some part of the year in the U.S, 72% in Canada, and all of them migrating through Mexico on the way south to their wintering grounds. They are a U.S.-Canada Stewardship species and rate a 9 out of 20 on the Continental Concern Score. They are not on the 2014 State of the Birds Watch List.
