Male American Goldfinch with winter plumage. Here he is eating his breakfast.
American goldfinch (Spinus tristis), also known as eastern goldfinch is a small bird in the finch family. It is migratory, ranging from mid-Alberta to North Carolina during the breeding season (summer), and from the Canada/US border to Mexico during the winter. It is a granivore and adapted for the consumption of seedheads.
The only finch in its subfamily to undergo a complete molt, the American goldfinch displays sexual dimorphism in its coloration; the male is a vibrant yellow during the breeding season and an olive color during the winter. The female is a dull yellow-brown shade which brightens only slightly during the summer.
