Aberrant Bush Warbler
Horornis flavolivaceus
Small shy warbler. Dull brown with a paler belly and brow stripe. Like most bush-warblers, difficult to see as it moves through dense foliage. Listen for its sweet song, consisting of a few introductory notes followed by two long whistles: “ti-ti-tchew weeeeee-cheeeeee’. Visually very difficult to separate from Yellowish-bellied Bush Warbler and Brownish-flanked Bush Warbler, and differences are extremely subtle. Himalayan breeders average more greenish on the back than either of the other two species, and have a strong yellow wash on the belly; Brownish-flanked, with which Aberrant overlaps in the eastern Himalayas, is much browner overall. In central China, Aberrant overlaps with Yellowish-bellied, which has a pale gray throat instead of a yellowish-buff one. Aberrant breeds in shrubby edge, bamboo stands, and open bushy areas in montane and hill areas; upper altitudinal limit averages higher than both Yellowish-bellied and Brownish-flanked.
分类信息
The aberrant bush warbler was formally described in 1845 by the English zoologist Edward Blyth based on a specimen collected in Nepal. He placed the species in the genus Neornis and coined the binomial name Neornis flavolivacea. The specific epithet flavolivaceus combines the Latin flavus meaning "yellow" with the Modern Latin olivaceus meaning "olive-green". The aberrant bush warbler is now placed in the genus Horornis that was introduced in 1845 by Brian Hodgson.<p>Thirteen subspecies are recognised:<p>The last eight subspecies in the above list have sometimes been considered as a separate species, the Sunda bush warbler Horornis vulcanius.

Buff-bellied Hummingbird
Amazilia yucatanensis
Green hummingbird with red bill, orange tail, and buffy patch on belly. The namesake belly patch can be difficult to see; tail and bill color are better ways to separate it from other hummingbirds. Males and females similar. Common in Mexico; limited range in U.S. Found in a variety of wooded or shrubby habitats, usually around flowers. Visits hummingbird feeders.
Andaman Coucal
Centropus andamanensis
A large, pale-brown, ground-dwelling cuckoo with rusty wings and back. Skulks in bushes and low cover, where it moves clumsily as it searches for small invertebrates, small mammals, and birds to prey on. Like other coucals, it is a cuckoo that builds its own nest. Common throughout its range in gardens, groves, disturbed forests, paddyfields, etc. The song is a series of deep and resonant “hoop” notes.
Indian Roller
Coracias benghalensis
A brightly colored bird with various shades of blue on the wings, tails, and belly that are often more prominent in flight. Note the longitudinal white streaks on the throat and breast. Indochinese Roller has a purple-blue breast, a darker olive back, and is generally darker blue. Generally silent, but more vocal in breeding season with harsh calls. Prefers open areas, including agricultural landscapes, sitting on exposed perches including electric wires, occasionally pumping its tail slowly. Practically a resident roller with some movements in the western parts of its range.
