Pine Siskin

Overview

The Pine Siskin is a small, heavily streaked finch related to goldfinches, best recognized by flashes of yellow in its otherwise brown, streaky wing and tail feathers. It is an irruptive species, meaning its winter numbers and range shift year to year depending on conifer seed availability.

Because of these unpredictable movements, siskin feathers can turn up far outside the usual range in some winters and be absent in others.

Recognizing the Feathers

• Body feathers: brown with dense, fine dark streaking throughout, no plain patches
• Wing feathers: dark with yellow edging, forming a yellow flash visible in flight
• Tail feathers: dark with yellow at the base, especially visible from below
• Face feathers: finely streaked, no bold facial pattern

The combination of dense streaking overall plus yellow highlights in the wing and tail feathers is the best clue, distinguishing it from other streaky finches and sparrows that lack yellow tones.

Plumage

Sexes look similar, both heavily streaked brown with yellow patches in the wings and tail, though the yellow can be brighter in some individuals. Juveniles resemble adults. One complete molt occurs after breeding.

Habitat & Range

Pine Siskins breed in coniferous and mixed forests across Canada, the northern United States, and western mountains. Their winter range is highly irregular, with irruptive movements bringing large numbers south in some years and few to none in others.

Behavior & Field Notes

Siskins feed on conifer seeds, thistle and other small seeds, often in large, active flocks, and are frequent visitors to nyjer feeders during irruption winters. Their calls include a distinctive rising, buzzy note. A finely streaked brown feather with yellow edging in the wing or tail is a good identifier for this species.
