House Finch

Carpodacus mexicanus

House Finch
copyright Richard P. Dunbar
Length: 6 in. (15 cm)
A native of the west, the House Finch is abundant in suburbs and cities but also does well in desert scrub and open woodlands. Because of its beautiful song, it was introduced to Long Island in the 1940s, and escapees and their offspring quickly populated much of the rest of the east. It feeds almost exclusively on seeds and unlike most other seed-eating species that switch to insects for their young, the House Finch also feeds seeds to its nestlings. This species uses a wide variety of nest sites, but the nest is often placed in a shaded niche or shallow cavity. The four-digit banding code is HOFI.
