Golden Grosbeak
Pheucticus chrysogaster
The body averages 21 cm (8.3 in) in length. The bill is large and conical in shape, typical of most species in the family. The golden grosbeak is sexually dimorphic in plumage. Males are bright yellow with a black wing and back. They have white spots on their median and greater wing-coverts that wear over time, and older birds appear darker. The females have brown wings and brown streaks covering the head, flanks, back and rump. The immature of this species look similar to the female in plumage and is often not distinguishable in the field.
