Yellow-billed Shrike

Corvinella corvina

Medium65 gShrubland

The yellow-billed shrike is 32 cm (13 in) with a long, graduating tail and short wings. The adult has mottled brown upperparts and streaked buff underparts. It has a brown eye mask and a rufous wing patch, and the bill is yellow. Sexes are largely similar, but females have maroon patches on the flanks, while males have rufous parches; these patches are only visible when the bird is in flight, displaying, engaging in territorial disputes, or preening. Immature birds show buff fringes to the wing feathers. The legs and feet are black, and the beak is yellow, even in juveniles.
