Boreal Chickadee
Learn to identify the Boreal Chickadee by ear. Master the "seee-u, seee-u" phrase and tell it apart from similar species.
What the Boreal Chickadee sounds like
A fussy tseeka-say phrase ends in an especially hoarse, dragged-out note. It is rougher than the pure fee-bee whistle of a Black-capped Chickadee.
How to tell it apart
Where you'll hear it
It lives year-round across much of Canada and Alaska, with a smaller range in the northern U.S. In some winters, a few wander farther south in irregular flights called irruptions.
Look for it in dense conifer forest—spruce, fir, tamarack, and mossy bog edges are classic spots. It favors the cool, resin-scented heart of the boreal woods.
It can be tough to notice in fall and early winter, when it stays quiet in conifer flocks. Late winter and spring are better, when its hoarse songs start carrying through the trees.
How to recognize it by sight
A soft-colored chickadee of the deep north, with a chocolate-brown cap, bright white cheeks, and warm rusty sides. It feels quieter and shyer than a Black-capped Chickadee, often slipping through spruce and fir like a little gray-brown shadow.
