Groove-billed Ani
Crotophaga sulcirostris
Anis are bizarre, coal-black cuckoos with long floppy tails and unique, curiously tall, flattened bills. Groove-billed occurs in a variety of open and semi-open habitats in tropical lowlands and foothills, typically staying low in shrubs and grasses. Gregarious and not particularly graceful; usually seen crashing around awkwardly in small groups. Flies with choppy wingbeats and long glides. Widespread and common throughout Middle America, as far north as Texas. In South America, primarily occurs west of the Andes; also in inter-Andean valleys and lowlands of northern Colombia and Venezuela. Compare with the very similar Smooth-billed Ani, which overlaps locally. Note especially the bill shape: Groove-billed typically has a lower, more evenly rounded top edge to the bill without an obvious keel, and the lower edge of the bill is straighter. Grooves are distinctive but can be difficult to see. Voice is also important: listen for a sharp “PIT!-tooee” and other sharp clicks and whistles.
识别特征
The groove-billed ani is about 34 cm (13 in) long, and weighs 70–90 g (2.5–3.2 oz). Wingspan ranges 41-46 cm (16-18 in). It is completely black, with a very long tail almost as long as its body. It has a huge bill with lengthwise grooves running the length of the upper mandible. It is very similar to the smooth-billed ani, some specimens of which have bills as small as the groove-billed and with grooves on the basal half. The two species are best distinguished by voice and range. In flight, the ani alternates between quick, choppy flaps and short glides.
分类信息
The groove-billed ani was formally described by the English naturalist William John Swainson from a specimen collected in Temascaltepec, Mexico. It still bears its original binomial name of Crotophaga sulcirostris. The specific epithet combines the Latin sulcus meaning "furrow" with -rostris meaning "-billed". The species is monotypic: no subspecies are recognised.

Crossley's Ground-Thrush
Geokichla crossleyi
A rather large, secretive, variable ground-thrush with mostly orange-rufous underparts and olive-brown upperparts, double white wingbars, and a distinctive smudged blackish mask spreading from the base of the bill to the ears, broken by a partial white eye-ring behind the eye. Rare, found in pairs in montane forest between 800 and 2300 meters of elevation in two discrete populations in the Cameroon Mountains and the Itombwe Highlands. Prefers wetter forest, including gullies and ravines where it forages on the ground, but sings from the forest canopy. Song is a rich mellow series of whistles, “chroo-woo-doo-too-loo-do-chu”; alarm call is a typical high-pitched thrush “ssreee.” No other ground-thrushes have a black face mask.

Equatorial Antpitta
Grallaria saturata
Plump, short-tailed, and long-legged bird found in Andean cloud forest in Ecuador, northern Peru, and the central Andes of Colombia; also known from one site in Colombia’s eastern Andes. Plumage is chestnut-brown with a slightly paler belly. Smaller and plainer than other highland antpittas in its range. Stays low inside high elevation cloud forest and heard far more often than seen. Songs include a short, whistled “wit, wi-di-dit” and a descending trill. Formerly called Rufous Antpitta.

Ornate Sunbird
Cinnyris ornatus
Tiny and active sunbird of forest edges, parks, and gardens; the most common urban sunbird throughout most of its expansive distribution; ranges from Andaman and Nicobar Islands to Lesser Sundas. Both sexes have a plain olive back, a yellow belly, and white tail edges that are flared out in flight. The male flashes an iridescent blue throat while the female has a yellow throat and eyebrow. Female Brown-throated Sunbird also has a yellow belly, but it is larger with a thicker bill and lacks the white tail patches of Ornate. Gives a rising “dwee”, a familiar sound even in cities. Formerly grouped with other, closely related species under “Olive-backed Sunbird.”
