Emerald-chinned Hummingbird
Abeillia abeillei
Very small, short-billed hummingbird of humid evergreen and pine-evergreen forest in highlands and upper foothills; uncommon. Usually feeds low, often at banks of flowers along edges and roadsides. Feeding flight is usually quick and hard to follow. Best identified by small size, big white spot behind eye, and rather liquid twittering call (similar to Stripe-tailed Hummingbird, which occurs in the same areas but looks quite different).
识别特征
The emerald-chinned hummingbird is 7 to 8.6 cm (2.8 to 3.4 in) long and weighs about 2.7 to 3.5 g (0.095 to 0.12 oz). Both sexes of both subspecies have a short, straight, dull black bill. The nominate adult male has metallic bronze green to greenish bronze upperparts. Its central pair of tail feathers are bronze green and the rest black with a faint bluish or bronzy gloss. All have brownish gray tips. Its face has a bold white spot behind the eye. Its chin and upper throat are brilliant metallic emerald green and the lower throat velvety black to dusky metallic bronze green. The rest of its underparts are deep brownish gray with some metallic bronze green gloss except on the belly. The undertail coverts are metallic bronze green with wide brownish gray edges to the feathers. Nominate females are similar to the male but lack the metallic throat. Their underparts are entirely pale gray with some metallic green spots on the sides. Subspecies A. a. aurea is smaller than the nominate. Where the nominate male is bronze green, this subspecies is golden green.

行为
The emerald-chinned hummingbird's movements, if any, are not known.<p>The emerald-chinned hummingbird forages low to the ground for nectar, usually in cover. Its diet has not been detailed but is known to include the flowers of Rubiaceae, Verbenaceae, and Oenotheraceae. Males defend clusters of flowers. In addition to nectar, the species feeds on small insects that it gleans from flowers, leaves, and tree trunks while hovering.<p>Little is known about the emerald-chinned hummingbird's breeding phenology. It is reported to nest in Mexico during February and March, and to build a cup nest low in the forest understory. Its incubation length and time to fledging are not known.<p>The emerald-chinned hummingbird's song is "a high, thin, slightly squeaking chipping, tsin, tisn-tsin tsin-tsin tsin-tsin, or tsi tsi tsi-si, tsi-tsi tsi tsi-tsi..." When foraging it gives "a liquid, rattling trill ... at times only single notes given, puip puip" and when perched "a sharp sii'ing".

Sooty Barbet
Caloramphus hayii
Earth-toned bird with a large, powerful bill. Dark brown above and white below with a rusty-orange head and chest; the only predominantly brown barbet in its range. Inhabits both primary and secondary forests, occasionally venturing into edge habitats. Unlike other barbets, does not have a loud rollicking song; instead, listen for its high thin “tseep” notes, often given in series.
Cassin's Honeybird
Prodotiscus insignis
A small, upright honeyguide of forest and forest edge, where it forages for insects and flycatches into the open. Plumage is a relatively uniform olive-green to green, with a paler throat, small pale eye arcs, and bright white outer tail feathers that are obvious when flying out for insects. Similar to Green-backed Honeyguide and Wahlberg’s Honeyguide, but differs in range, in its overall greenish coloration including the belly, and in its clean white outer tail feathers. Voice is little known, but apparently gives a buzzy trill in flight that rises and falls in pitch.
Short-tailed Batis
Batis mixta
Males have the typical batis pattern of black, white, and gray. Females have a more unusual pattern, with rufous in the wing and either a rufous or gray wash across the breast. Both sexes have a narrow pale eyebrow and orange or reddish eyes. Found in forest at low and middle elevations, often in pairs. Very similar to Dark Batis, but there is no known overlap in range. Males are similar to Chinspot and Pale Batises, but are distinguished by the darker eye and shorter tail. Females are distinctive. The song is variable, but is usually a long series of identical low-pitched tooting notes.
