What the Pine Siskin sounds like

The Pine Siskin is a tiny, streak-lined finch best known for its nomadic, boom-and-bust winter movements. About the size of a goldfinch, it wears cryptic brown plumage heavily streaked with dark lines, accented by flashes of lemon-yellow in the wings and tail that sparkle when it flits about in tight, fast-moving flocks. Extremely gregarious, it descends on backyard feeders in noisy hordes during irruption years, then may disappear again for several seasons.
