Of the many seed-eating birds found in the coniferous forests, the largest by far is the common pine chuck. The two sexes of this species are quite different, both in appearance and in their mode of life. The male is much more powerfully built and is equipped with a massive beak, which he uses for breaking open pine cones to feed on the seeds. The female, much smaller and drabber, totally lacks the male's heavy beak and is really a scavenger supplementing her diet with carrion, grubs, adult insects, and other birds' eggs.
