Stan's Notes: A common backyard resident year-round, moving around to find adequate supplies of food during winter. Most often in open fields, scrubby areas, and woodlands. Enjoys Nyjer seed in feeders. Breeds in late summer, using the silky down from wild thistle for its nest. Appears roller-coaster-like in flight.
Listen for it to twitter during flight. Almost always in small flocks. Often called wild canary.
