Pine Grosbeak |
These plump finches dwarf every other finch in the trees and nearly every bird that lands on the feeder. The grayish bodies of Pine Grosbeaks are decked out in pinkish reds on males and yellows on females. They easily crush seeds and nip off tree buds and needles with their thick and stubby bill. They breed in open spruce, fir, and pine forests, but they drop in on feeders in winter, especially in the East when they sometimes irrupt outside of their normal range.
Pine Grosbeaks eat a lot of plants, but it can be tough for their nestlings to eat and digest all that vegetation. Instead of feeding plants directly to their nestlings, they regurgitate a paste of insects and vegetable matter that they store in pouches at the lower part of their jaw on either side of their tongues.
