Species: Common Yellowthroat
Most recent capture date: 5/26/2021
Age: less than two months old
Notes: You can see the yellow “gape” at the base of the bill on this very young warbler. Brightly-colored gapes help baby birds beg for food, exaggerating their open-mouthed begging movements, but the gapes quickly disappear as they grow up. If you see yellow gape, you know you are looking at a brand new bird.
