Large-tailed Dove
Leptotila megalura
A medium sized, chunky dove of the interandean dry valleys, yungas, and Tucumán forest with mixed Podocarpus and alders. Often alone or in pairs. Orbital ring varies from blue-purple north of the bend in the Andes to red south of this bend. Range overlaps with the very similar White-tipped Dove, and is best separated by voice, and, in some populations, orbital skin color (blue in White-tipped Dove). Iris also generally darker than White-tipped Dove. Most often found and easily identified by its low-pitched, stuttering song.
识别特征
The Yungas dove is 29 to 32 cm (11 to 13 in) long. The adult's forehead is grayish and its crown bluish gray. The eye is very dark and is surrounded by white feathers; the rest of the face is buff or pinkish buff. Its upperparts and tail are a dark ruddy brown with a purple gloss on the hindneck and upper mantle. Its breast and the sides of the neck are grayish pink lightening to white on the belly. The adult sexes are similar; the juvenile is duller and its wing coverts appear scaly.
分类信息
The Yungas dove is monotypic. However, the southern population has sometimes been suggested as a distinct subspecies. The Yungas dove and the grey-fronted dove (L. rufaxilla) are sister species.

Cinnamon Attila
Attila cinnamomeus
Medium-sized sluggish flycatcher of riverine and disturbed habitats. Key marks are entirely cinnamon plumage and large-headed, plain-faced appearance; bill seems heavy and is entirely black. Sits still, peering about, before sallying to foliage for insects. Inhabits mid-story and understory, often at forest edge. Found in forest along rivers and oxbow lakes, in abandoned plantations, and at savanna edges, usually near water. Similar to Dull-capped Attila but has dark eyes and different voice. Most common calls are various mournful whistles.

Philippine Swiftlet
Aerodramus mearnsi
Uncommon dark swiftlet. Endemic to a smattering of the Philippines islands, from Luzon to Mindanao to Palawan. Habitat can be helpful in identifying this confusing species; generally favors ridges and slopes in montane and submontane areas above 700-800 meters. Readily confused with significantly larger Ameline Swiftlet, but present species has a more squared-off-looking tail (fork is shallow and often unnoticeable), tends to fly lower and more erratically, and more often forms flocks. Combination of dark rump, unglossed dark back, and medium size separates this species from Gray-rumped Swiftlet, Pygmy Swiftlet, and Ridgetop Swiftlet. Frequently calls while in flight, giving a squeaky chattering twitter.

Philippine Green-Pigeon
Treron axillaris
A medium-sized pigeon of lowland and foothill forest canopy, with green underparts, head, and rump, a gray crown, yellow wingbars and edges to the flight feathers, a whitish belly, and white under the base of the tail. Note the whitish bill with a reddish base and the blue eyes. Male has a maroon shoulder and back, where the female is green. Similar to Thick-billed Green-Pigeon, but Philippine has a thinner bill and lacks the green skin around the eye. Female resembles female Pink-necked Green-Pigeon, but that species has yellow marks only on the edge of the wing. Voice is typical of green-pigeons, including a rising-and-falling out-of-tune whistled song.
