Yellow-bellied Whistler

A small barbet of dense, broad-leaved forests in lowland and foothill regions. Adult is bright green with a blue face patterned with a complex mosaic of black, red, orange, and yellow. Juvenile is green with a powder-blue face and no dark markings. Like most other barbets, tends to stick to dense canopy and is seldom seen, but its far-carrying song is often heard: a long steady series of single or doubled chirping notes that somewhat resemble a frog’s. Also gives a series of rising peeps: “weet, weet, weet.” Overlaps with Blue-eared Barbet (with which it is treated as one species by some taxonomies) in far southern Thailand and northern Malaysia.

Medium-sized woodcreeper with a slightly curved bill. Has buff spots on its head which become elongated semi-circles with dark edges on the mantle and underparts. Found in the understory of humid forest, where it regularly accompanies mixed-species flocks and occasionally attends army-ant swarms. The song is a fast trill that ends with a whine “-wheu.” Best distinguished from the similar Striped Woodcreeper by Spix’s darker bill, darker and less contrasting head, and different song and habitat.

A medium-sized reed warbler, bright yellow below and tawny above, with pale-edged black wing feathers. Bill long and slightly downcurved, giving the bird a very “long-headed” appearance. Found in scrubby areas and plantations, avoiding deep primary forest. Call is a harsh “tchak.” Song is a mix of whistles, churring, warbling, and rasping scold notes.
