Siskins are seed specialists, often hanging upside down to pluck seeds from hanging seedpods and cones. Their primarily feed on the seeds of hemlocks, alders, birches, and cedars. Pine Siskins are irregular migrators, often invading the central latitudes of North America in large numbers during winter. The cause is believed to be fluctuations or a lack of food at their typical wintering grounds.
