Gray-crowned Goldfinch Carduelis caniceps

Beautiful little finch with a sharp pink bill, cherry-red mask, and brilliant black-and-yellow flashes in the wings. Juvenile (seen in late summer and autumn) has a plain head but is told easily by bold wing pattern. Uses a wide array of wooded and open habitats, from forests and gardens to steppe grasslands and meadows; often feeds on seeding thistles. Forms flocks in autumn and winter, gathering at food sources. Can be inconspicuous, but often detected by pleasant bubbling and twittering calls and song.
