Galapagos Martin
Progne modesta
Large, very dark swallow endemic to Galápagos. Male is entirely deep bluish black. Female and juvenile are mostly brown with a bluish tinge to upperparts. In flight, note triangular wingtips and notched tail. Very similar to Purple Martin, which is a rare and erratic visitor (most records are from October to January). Male Galápagos Martin is smaller but otherwise looks almost identical; female is uniform brown below, lacking a pale belly. Uncommon and endangered, with a population estimated at less than 1000 birds. Usually encountered in pairs or very small groups circling overhead as they hunt insects.

Black-capped Tinamou
Crypturellus atrocapillus
Subtly colorful tinamou of dense habitats in the lowlands and Andean foothills. Almost exclusively found in bamboo thickets, but also occasionally found in dense riverside vegetation and secondary growth, including around agriculture. Rarely seen, but frequently heard throughout the day; it usually gives about one call note per minute, a springy “bwow”. The most helpful visual field mark is its bright orange legs; it also has a black or dark gray cap, and brown plumage with cold gray head and neck, and reddish orange throat.
Gabon Coucal
Centropus anselli
A large, reddish-bellied forest coucal of Central African forests, occasionally found in more open and disturbed habitats. Most often detected by its call, which is a long or short series of hollow loud hoots, the last few usually lower, sometimes given as a duet. Overlaps locally with Black-throated Coucal, which has a black throat and a cream-colored belly.
Rufous Treepie
Dendrocitta vagabunda
A long- and stiff-tailed bird with primarily rusty-brown upperparts and dull orangish underparts. The head, mantle, and neck region are a dull, sooty black. The long graduated tail is pale gray with a wide black terminal band. Note the conspicuous silvery-gray, white, and black patterns on the wings. The blackish-gray bill is stout with a hooked tip. Found in a wide range of habitats from woodlands to scrubby patches, singly or in pairs feeding in the treetops. The call is a loud metallic “krowwiiii kroo.”
