Costa Rican Warbler

Small forest bowerbird. Males and females differ greatly. Males are black with stunning bright gold on the head and wings. Females are light brown with scalloping on the breast and back; they are much smaller and more lightly build than big, plump Satin Bowerbirds. Males have a bright yellow bill, while female’s is black-gray. Usually found in rainforest. The male builds a small open bower out of twigs and decorates it with small objects in order to attract a mate. This species is not very vocal and is usually only heard calling near a bower.

A small greenish bird with a barred chest and tail, and a dark stripe through the eye that droops down across the cheek. Young birds can be almost unbarred and may appear similar to the grayer Black-eared Cuckoo. Often perches prominently on top of a shrub or tree, and calls repeatedly with a loud piercing descending whistle. Occurs in Indonesia and across much of Australia (including arid inland areas).

Plain grayish-brown thrasher of the southwest U.S. and Mexico. Look for decurved bill and fairly faint round spots on breast and belly. Undertail coverts are slightly warmer buffy. Eye color varies from yellow to orange. Occurs in deserts and open, shrubby areas. Can be shy and skulking, but often perches atop a bush or cactus to sing. More common in suburban areas and parks than other thrashers in range. Most similar to Bendire’s Thrasher. Note Curve-billed has a slightly longer and more curved bill, and breast spots are slightly larger and rounder.
