Stan’s Notes: Common backyard resident. Most often found in open fields, scrubby areas, and woodlands. Enjoys Nyjer seed in feeders. Breeds in late summer. Lines its nest with the silky down from wild thistle. Almost always in small flocks. Twitters while it flies. Flight is roller coaster-like. Moves around to find adequate food during winter. Often called Wild Canary due to the male’s canary-colored plumage. Male sings a pleasant, high-pitched song. The state bird of New Jersey.
