Short-tailed Parrot
Graydidascalus brachyurus
Medium-sized, uniformly bright green parrot with a short tail. Note the indistinct black eye-line, the dusky bill, and the darker green flight feathers; other parrots have more colorful plumage and longer tails. Inhabits seasonally flooded forest along large rivers, occasionally venturing into adjacent urban areas.
识别特征
The short-tailed parrot is 24 to 25 cm (9.4 to 9.8 in) long and weighs 188 to 233 g (6.6 to 8.2 oz). It has a large head and, as suggested by its name, a very short tail. Adults are almost entirely green that is yellowish on their underparts and their uppertail coverts. Their lores are dark which continues behind the eye. Their primaries are a darker green and their wing coverts have yellow edges. Their shoulder is a reddish brown that is seldom visible except in flight. Their outer tail feathers have red bands at their base. Their bill ranges from light green to dark gray and their iris is orange-red. Immature birds are the same as adults except they have no red on their tail.

分布与栖息地
The short-tailed parrot is found along the Amazon River and its tributaries from southern Colombia, northeastern Ecuador, and northeastern Peru to the Atlantic. Its range also extends north along the coast of Brazil into northeastern French Guiana. Along the rivers it inhabits várzea, swampy floodplains, and islands; on the coast it inhabits mangroves. It also locally ranges into cultivated areas. In elevation it ranges from sea level to about 400 m (1,300 ft).

行为
The short-tailed parrot is thought to make some movements, perhaps in response to the timing of seasonal flooding.<p>The short-tailed parrot feeds on fruits, especially those of figs (Ficus), and on those of cultivated guava (Psidium guajava) and mango (Mangifera indica). It also feeds on seeds, nuts, berries, and the catkins of Cecropia.<p>The short-tailed parrot's breeding season appears to include September but nothing else is known about its breeding biology.<p>The short-tailed parrot is rather noisy. Its flight call is "a rather high-pitched rolling “kree-ki-ki”." It makes a variety of loud, harsh, "conversational" calls when perched.

Tropical Screech-Owl
Megascops choliba
As with all screech-owls, much easier to identify by voice: a short rapid trill with a pop at the end. If you’re lucky enough to see one, look for an overall grayish-brown or rufous bird with fine markings, including thin streaks on underparts. Black border to face. Sexes alike. Found in wooded habitats, sometimes coming out into open shrubby fields or gardens with only a few scattered trees. Usually the most common screech-owl in range.
Australasian Grass-Owl
Tyto longimembris
Reclusive and rarely seen owl of cane fields, meadows, and other areas with tall grassy cover. Tan-brown overall with black, white, and orange mottling on the wings. Flies low over grassy areas, primarily during dawn and dusk, often with long legs dangling. Heart-shaped facial disk, very similar to Barn Owl and Masked Owls. Nests in dense fields; fluffy owlets often exposed during harvesting season in agricultural areas.
Banded Yellow Robin
Eopsaltria placens
A medium-sized, localized bird of foothill forest. Orange legs, gray head and wings, olive back and chest band, bright yellow belly and incomplete collar from the lower throat around to the sides of the neck. Perches low down, motionlessly scanning the forest floor. Distinctive, but somewhat similar to Green-backed and White-faced Robins which both have white on the face. Song, a series of whistled notes “pwip! pyuu-pyuu-pyuu-pyuu-pyuu”. The first note rising followed by a gap, the followed by identical notes.
