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.

Rose-breasted Grosbeak
Pheucticus ludovicianus
Adult birds are 18–22 cm (7.1–8.7 in) long, span 29–33 cm (11–13 in) across the wings and weigh 35–65 g (1.2–2.3 oz). Grosbeaks measured during migration in the West Indies averaged 43 g (1.5 oz), while those banded in Pennsylvania average about 45 g (1.6 oz). Very little sexual dimorphism in size is seen; females were found to be marginally smaller in standard measurements, but in some seasons were marginally heavier than males when banded in Pennsylvania. At all ages and in both sexes, the beak is dusky horn-colored, and the feet and eyes are dark.
