Chico's Tyrannulet

Large, dark swift of tepui highlands. Note generally dark appearance, broad wings, and forked tail. If seen in good light, chestnut collar of adult is diagnostic; otherwise this species may be difficult to distinguish from other large swifts, especially at a distance. Found around the tepuis and down to at least 400 meters in the surrounding region. Forages high for insects, often with other swifts; may descend to just above treetop level to feed on swarms of emerging winged ants and termites. In poor light, most similar to White-chinned Swift but has more deeply forked tail.

A dark ducklike waterbird with blue-green eyes, a rounded head, a sloping forehead, and a long and slender bill that is sharply hooked at the tip. Adults are black, immatures are brownish with white underparts. Like all cormorants, frequently seen swimming with its body low in the water, head and neck pointing upward, and suddenly disappearing underwater to catch fish. Often perches upright on a rock, drying itself with outstretched wings. Seen in small groups, fishing communally in inland water bodies. Similar to Little Cormorant, but note the slightly larger size and shape of the head, flat on Little Cormorant and rounded on Indian Cormorant. Indian Cormorant is smaller and slimmer than Great Cormorant.

Large hummingbird with long white-tipped central tail feathers. Male is entirely blue-green; female has gray belly, green back, and obvious stripes on face. Bill extremely long and decurved. Found in forest, but also visits feeders at forest edge. Not easy to see away from feeders; often flies through the forest understory very quickly, occasionally stopping to feed at flowers.
