[edit] Identification

19cm
Olive upperparts, white belly, yellow throat and breast, long tail, thick heavy bill, large white eye-ring, and dark legs.

[edit] Distribution

Breeds in USA, western half of southern Canada and northern Mexico. Recent results suggest that at least part of the US population after having bred in early parts of summer migrates to north-western Mexico where a second round of breeding takes place before the birds go on the final migration to their winter home.

In winter found in Mexico (mostly southern half) though Central America to Panama.
