Buffy-crowned Wood-Partridge
Dendrortyx leucophrys
Very elusive, chickenlike bird of humid evergreen and pine-evergreen forests and adjacent shade-coffee plantations in the highlands of extreme southeast Chiapas and from Guatemala to Costa Rica. Usually in pairs or small groups on the forest floor; may be seen beside quiet trails and roads early and late in the day. Runs away quickly and rarely flies. Note the white crown and throat, dark bill, and red eyering. Loud rollicking songs are given mainly early and late in the day and most often reveal its presence.
识别特征
The buffy-crowned wood partridge is 28 to 35.5 cm (11.0 to 14.0 in) long. Males weigh an estimated 397 g (14.0 oz) and females an estimated 340 g (12 oz). The nominate subspecies' forehead, supercilium, chin, and throat are white. It has a patch of bare red skin around the eye. The crown, its short crest, and the nape are chestnut and the back, wings, and tail are chesnut and gray. The belly is blue-gray with chestnut streaks. D. l. hypospodius is larger, darker, and grayer. The stripes on the breast are very dark and much narrower.
分类信息
The holotype of the buffy-crowned wood partridge was collected in Cobán, Guatemala, in June 1843 by Adolphe Delattre and given the binomial Ortyx leucophrys. It was originally in the collection of the 13th Earl of Derby who bequeathed it to the people of Liverpool in 1851. It is housed in the World Museum of the National Museums Liverpool with accession number D1496.<p>The buffy-crowned wood partridge shares the genus Dendrortyx with two other species, all of which appear to be quite distinct from each other. It has two subspecies, the nominate Dendrortyx leucophrys leucophrys and D. l. hypospodius. The latter has sometimes been considered a separate species. The members of D. l. leucophrys in Honduras and Nicaragua were previously treated as another subspecies.

分布与栖息地
The buffy-crowned wood partridge is found in three separate areas. The nominate subspecies is found from Chiapas in southern Mexico into western Guatemala and in Honduras, El Salvador, northwestern Nicaragua, and far eastern Guatemala. D. l. hypospodius is found in central Costa Rica. The species inhabits several humid to semi-humid montane forest types including oak-pine, evergreen, and cloudforest. It can be found in secondary forest, partially logged areas, and coffee plantations.

行为
The buffy-crowned wood partridge apparently forages by scratching through leaf litter. Its diet has not been well studied but includes seeds, buds, small fruits, and invertebrates. It moves about in family groups of four to six and in the non-breeding season in coveys of up to 12.<p>The buffy-crowned wood partridge's nesting season appears to span from February to June. It generally nests on the ground, either building a domed structure or hollowing out a space in dense grasses. The clutch size is six to seven.<p>The buffy-crowned wood partridge's primary vocalization is "a rapid series of loud hoarse whistles 'kee-orr-KWA' or 'whew, Whit-cha, cha-waWHAT-cha'", usually preceded by a few hard to hear soft notes. It calls the most at dawn and into daylight and again at dusk.

Barred Fruiteater
Pipreola arcuata
Chunky, short-tailed, flat-headed bird patterned in green and black. Male has black head and breast, pale yellow belly with bold dark barring, and mossy green upperparts with bold pale spotting on the wing. Female is similar but has a green head with barring all the way up the throat. On both sexes, note red bill and legs and pale eye varying from orange to gray to whitish. Fairly common in stunted forested habitats in the upper subtropical and temperate zone in the Andes. Sluggish; perches quietly in the middle levels of the forest, sometimes following a mixed-species flock. May be seen singly or in pairs, but several can gather around a fruiting tree. Listen for super high-pitched calls.
Jandaya Parakeet
Aratinga jandaya
Strikingly colored parakeet with a yellow head and chest, orange around the eyes and bill, orange on the belly, and blue flight feathers. Highly gregarious and noisy; can be seen flying over forests, woodlands, and agricultural areas, as well as in cities.
Black-faced Hawk
Leucopternis melanops
Smallish chunky hawk. Identifiable by size, shape, and prominent black mask contrasting with orange cere. Generally rare. Inhabits wet forests where it hunts from the mid-level to the ground; often perches well below canopy level. Takes relatively small prey, chiefly frogs and snakes. Superficially similar to White Hawk but much smaller with orange (not blue-gray) cere; unlike White Hawk, Black-faced tends not to soar for long periods and is less frequently seen than White Hawk.
