Sapphire-bellied Hummingbird
Chrysuronia lilliae
Rare, endangered, and poorly known hummingbird restricted to mangroves and adjacent scrubby areas along the Colombian coast. Male has sapphire underparts extending from throat all the way to belly, and lacks the distinct hood typical of the more common Sapphire-throated Hummingbird. Female’s plumage is not known with certainty, but likely resembles female Sapphire-throated Hummingbird, which has white central underparts bordered by green flanks, and white tail tips.
识别特征
The sapphire-bellied hummingbird is 8.9 to 9.4 cm (3.5 to 3.7 in) long. Males weigh about 4.3 g (0.15 oz). Males' bills have a black maxilla and a black-tipped pinkish mandible. They have a shining green crown, back, and rump and their tail is forked and blue-black. They have a glittering purple gorget and the rest of their underparts are glittering blue. The female's weight has not been documented nor its plumage described, though the latter is thought to be similar to the male's but grayer on the underparts.
分类信息
The sapphire-bellied hummingbird was formerly placed in the genera Lepidopyga and Amazilia. A molecular phylogenetic study published in 2014 found that both genera were polyphyletic. In the revised classification to create monophyletic genera, the sapphire-bellied hummingbird was moved by most taxonomic systems to Chrysuronia. However, BirdLife International's Handbook of the Birds of the World (HBW) retains it in Amazilia. At times the species has been treated as a subspecies of the sapphire-throated hummingbird (C. coeruleogularis).<p>The sapphire-bellied hummingbird is monotypic.

行为
The sapphire-bellied hummingbird's movements, if any, have not been documented, though it might make local seasonal movements.<p>The sapphire-bellied hummingbird's preferred nectar source is the flowers of tea mangrove (Pelliciera rhizophorae), though it has been observed feeding at the flowering legume Erythrina fusca in the nearby arid scrub. In addition to nectar, it feeds on insects.<p>Nothing is known about the sapphire-bellied hummingbird's breeding phenology.<p>Xeno-canto and Cornell University's Macaulay Library have only a few recordings of the sapphire-bellied hummingbird's vocalizations. They are described as "a series of short chatters".

Allpahuayo Antbird
Percnostola arenarum
Scarce antbird described to science in 2001. It is found in lowland rainforest in northeastern Peru, only in areas with white, sandy soil. Male is gray with a black throat and white wingbars. Female has gray upperparts with tawny underparts and wingbars. Very similar to Black-headed Antbird, and best identified by voice, range, and habitat. Inhabits dense understory, often in areas with lots of palm saplings. Song is a fairly rapid series of ringing notes, higher-pitched and faster than the song of Black-headed Antbird.
Cape Bunting
Emberiza capensis
A gray-brown bunting with a boldly striped head and bright chestnut wings. Pairs and small groups are resident, preferring rocky areas in heathland, arid shrubland, woodland, and grassland, where they mostly hop on the ground searching for food. The song is variable, but is typically a slightly accelerating phrase of 5-6 similar well-spaced notes, “chet-shwit-set-chwit-chet-swit.” The distinctive call is a nasal rising “neeh-neerh-neeeerh-neh” or similar. Now includes Vincent’s Bunting of Malawi, which tends to be darker than Cape Bunting populations elsewhere.
Philippine Jungle Flycatcher
Cyornis ruficauda
Drab, medium-sized flycatcher with a long slender bill. Endemic to the central and southern Philippines, from the eastern Visayas south to Mindanao and Basilan. Look for a warm rufous tail, white throat, and diffusely brown-washed chest. Inhabits lowland and foothill forests, where it forays from a low perch in the understory or forest edge. Generally unobtrusive and difficult to spot in dark understory, but listen for its song, a jumbled series of high and squeaky notes often interspersed with short buzzes. Formerly grouped with Crocker Jungle Flycatcher and Sulu Jungle Flycatcher under “Chestnut-tailed Jungle Flycatcher.”
