Thick-billed Cuckoo

Fairly common but heard much more than seen. This demure little brown bird favors bamboo thickets and other dense tangles at forest edge, roadsides, and along streams. Usually in pairs that move quickly through cover, showing only briefly. Plumage is warm brown overall with paler eyebrow and beady dark eye; might suggest a House Wren but plumage lacks barring, and identified easily if long “wiretail” streamers are seen, such as when flying across a road or trail.

Distinctive, locally common nighthawk of lowland rivers. Appears small and dark; in dim light, best distinguished from other nighthawks by swallowlike profile and longish tail. Also note the white band across tail and lack of white in wings. Usually found near water in forest and savanna regions, occasionally in large groups; does not tend to fly high. Dark plumage recalls Blackish Nightjar, but shape and behavior are very different.

A medium-sized bird of lowland and foothill forest canopy and edge. Overall bright green with a paler green chest and face and a yellowish throat, eye-ring, and edge to the wing. Note the brown bill and black wingtips and legs. No other green birds of this size occur in its range. Song consists of simple, medium-pitched whistled phrases or a series of repeated “tyup!” notes.
