Blue Mountain Vireo

Small tinamou of floodplain rainforest. Reddish brown with limited black barring on the wings. Found in tall lowland rainforest, especially around water and in seasonally flooded areas, and can be quite common. Listen for a series of whistles given at a pace of about one note per four seconds that gradually accelerates until about twice as fast; recalls the song of Cinereous Tinamou, but faster and usually accelerating.

A bright green insect hunter with a long bill and triangular starling-like wings. Adult has a bright blue throat, orange-brown crown and nape, and long trailing central tail feathers. Sexes are alike. Juveniles have a paler blue throat, no orange-brown coloration, and no long tail extensions. Often hunts from exposed perches such as telephone lines or snags, on which it rubs its venomous quarry so as to disarm it. Call is a bright, inflected “chileep.”

Rather small hawk that is often seen soaring on flat wings with tips swept upwards, suddenly dropping out of the sky like a rock. Dark morph adult is very dark brown with paler undersides on outer flight feathers. Dark juvenile similar but is distinctly spotted below, and lacks the terminal band on the wings. Light morph adult is clean white below and brown above with rusty patch on the side of its neck, a dark hood and a white throat. Light morph juvenile is similar but lacks rusty patch. All birds have a faintly banded tail. Most similar to Broad-winged Hawk, which is never clean white below. Dark morph Broad-winged separable from dark morph Short-tailed Hawks by tail pattern and wing shape.
