Long-tailed Wood-Partridge
Dendrortyx macroura
Very elusive, chickenlike bird of humid evergreen and pine-evergreen forests in the highlands of central Mexico. 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 stripes on black head, red bill and eyering, and overall gray-brown body; tail often held cocked, like a chicken. Loud rollicking songs are given mainly early and late in the day and most often reveal its presence.
识别特征
The long-tailed wood partridge is 29.0 to 42.2 cm (11.4 to 16.6 in) long and weighs 266 to 465 g (9.4 to 16.4 oz). Males are heavier than females, and adults of both sexes have a long tail though the female's is somewhat shorter. In adults, most of the head is black; the face has white streaks above and below the eye. The short crest on the crown is tipped with buff. The upper back is chestnut edged with gray and the lower back is olive brown, black, and tawny mottling. The breast is bluish gray with chestnut streaks. The juvenile is similar but with dark brown spots and less chestnut on the underparts. There are variations among the subspecies, but it is unknown if there are vocal differences or genetic ones other than plumage color among them.
分类信息
The long-tailed wood partridge shares the genus Dendrortyx with two other species, all of which appear to be quite distinct from each other. It has these six subspecies:

分布与栖息地
The subspecies of the long-tailed wood partridge are distributed in four discrete zones.<p>The long-tailed wood partridge inhabits humid pine-oak, pine, fir, and montane evergreen forests with dense understories. In elevation it ranges between 1,200 and 3,300 m (3,900 and 10,800 ft).

行为
The long-tailed wood partridge forages mainly on the ground, scratching in leaf litter, but also climbs in low branches to search. Its diet is mostly seeds and small fruits but also includes small arthropods and leaves.<p>The long-tailed wood partridge's breeding season extends from February to September, with nesting itself beginning in late April. Four nests have been described. One was a depression lined with grass in a natural cavity in the ground. One was a cavity of pine needles at the base of a rock and the others were at the base of a rock outcrop and under a small shub. The last two were not well concealed. Three of them each contained four eggs and the other six eggs.<p>The long-tailed wood partridge's song is "complex, loud and rhythmic", usually given as a duet by both members of a pair. One description calls it "a loud, ringing korr-EEE-oh, korr-EEE-oh, korr-EEE-oh, korr-EEE-oh". Pairs vocalize at any time of day and night during the breeding season and mostly at dawn and dusk from a night roost otherwise. The species also has an alarm call, "a repetition of short low-pitched, unmodulated squeaky notes."

Great Myna
Acridotheres grandis
A black myna with a spiffy crest. Not actually significantly larger than other dark crested mynas, but the combination of the bright yellow bill, prominent spiky crest, and white vent serve to distinguish it from other similar mynas. Forages in flocks in open areas such as meadows, agricultural fields, and urban parks and gardens, often with other species of mynas and starlings.
Fire-bellied Woodpecker
Chloropicus pyrrhogaster
A large, long-billed woodpecker with an olive back, a red rump, a bold facial pattern, and heavily marked underparts with a bright red central belly stripe. The crown and back of the head are black in the female and red in males. Forages alone or in pairs, preferring dead tree trunks where it can excavate for beetle larvae and other insects in lowland rainforest, gallery forest, and plantations. Calls include a sharp “kwip,” a series of similar notes, and a fast whinnying call. Also gives a distinctive drum that lasts about 2 seconds, beginning fast and then slowing. Similar to Bearded and Yellow-crested Woodpeckers, but there is very little overlap in range, and those species lack the red belly patch.
El Oro Parakeet
Pyrrhura orcesi
Rare and endangered parakeet endemic to foothill cloud forest in southwestern Ecuador. It is mostly green with red on forehead, shoulder, and undertail. Flight feathers are blue, which is usually only evident in flight. Also note the whitish eyering and rather long tail. Usually encountered in small flocks that fly from tree to tree, screeching as they go. Most of the known population is found in and around the Buenaventura Reserve, where the birds are successfully using artificial nest boxes.
