observed "visiting" each other during nesting season. The Pine Siskin is often seen in the same areas as the American Goldfinch.

Scientific Name: Carduelis pinus
Location: The Pine Siskin can be found in coniferous or coniferous-deciduous mixed woods, shrubs, thickets, weedy areas, and suburban yards.
Migration: The Pine Siskin does not have a regular migration pattern. One year, this species may be abundant in a particular area, and might be completely absent the next year. Fluctuation in a reliable food source is thought to be a factor in their irregular migration. The Pine Siskin breeds in the spring and summer, anywhere from southern Canada and Alaska to the southern United States. This species winters as far south as northern Mexico.

Diet: In nature, the Pine Siskin forages for the seeds in conifer cones, weed seeds, insects, and flower buds.
