Pale-vented Thrush

A large owl of lowland and foothill forest, including secondary habitat and plantations. Warm brown with a heavily marked back, a heavily streaked rufous head and chest, and a more sparsely streaked pale belly. Note the square-shaped head with flattened ear tufts and the yellow eyes. Unmistakable. No other owls of similar size occur in its range. Gives a long, drawn-out, spooky whistled note whose pitch rises slightly, then falls at the end.

A small, sharp-billed warbler-like bird with an olive-green back, yellow underparts, and broad white spectacles around the eyes. Found in montane forest, forest edge, and lush gardens and scrub, usually in hyperactive flocks. Separated from similar broad-ringed white-eyes by range. Also somewhat similar to African Yellow and Pale White-eyes, but found at higher elevations, and has a much broader eye-ring. Most common call is a high-pitched, descending rattle. Song is a subdued, chatty sequence of “chew” notes. 

Medium-sized bird; heard far more than seen. All-white male is unmistakable; mostly green female is best identified by chunky proportions and long, sloping head profile. Found in tall forest, principally at higher elevations; common in the tepui region. Feeds at fruiting trees but is more often seen from high vantage points or flying across gaps. Males sing from bare snags above the canopy and are often not visible from below. Song is only vaguely bell-like, amazingly loud and reverberating; younger males may give a cracked or truncated version.
