Papuan Frogmouth
Podargus papuensis
Very large nocturnal bird with "frog-like" bill and long tail. Inhabits edges of dense forests, including mangroves. In daytime, often roosts above water. Primarily gray-brown with barred underparts and tail. Distinguished from other frogmouths by very large size. Call is a repetitive, low-pitched "oo-oo-oo-oo."
识别特征
The Papuan frogmouth is the largest of frogmouths in terms of length. Average sizes indicate that it only falls behind the Neotropical great potoo and oilbird (if the latter is a true member of the order) among the largest species in the order Caprimulgiformes.[citation needed] On average these birds are about 53 cm (21 in), with a range of 50 to 60 cm (20 to 24 in). This species was found to average 414 g (14.6 oz) in males and 314 g (11.1 oz) in females, with a total range of 290 to 570 g (10 to 20 oz). The tawny frogmouth is smaller on average than this but is capable of reaching higher maximum weights. The Papuan frogmouth has a bulbous bill, red eye, cream eyebrow, long tail and dark wings. The male of the species is slightly larger, darker and marbled in appearance. The female is more rufous in appearance.<p>P. p. baileyi is smaller, and darker. P. p. rogersi is larger and paler.<p>Similar species include the tawny frogmouth. The Papuan frogmouth is larger, has red eyes, a longer tail, and darker wings.
分类信息
The species was originally described by zoologist Jean René Constant Quoy and naturalist Joseph Paul Gaimard in 1830.<p>The three subspecies are P. p. papuensis, P. p. baileyi, and P. p. rogersi.

行为
The call is a resonant 'ooom' or a laughing hoot. It is usually heard after dusk and before dawn.<p>Breeding takes place from August to January. One or two white eggs are placed in a nest consisting of a few sticks placed in the fork of a branch.<p>The Papuan frogmouth is strictly nocturnal. It hunts for large insects on the ground from dusk. On occasion, it also takes small reptiles, amphibians, or birds as prey.<p>The Papuan frogmouth may secrete a substance in its mouth that attracts flies. According to a number of observers, it is able to wait with its mouth open and flies enter to investigate the odor.

Antioquia Bristle-Tyrant
Pogonotriccus lanyoni
Rare flycatcher known only from a few sites in the Colombian Andes, mainly in the northern part of the central range. It is fairly small and mostly yellow, with a gray crown and broad, yellow wingbars. Yellow and gray smudges on ears can be very indistinct. Often confused with the much more common Yellow-olive Flycatcher, but bill is narrower, wingbars are brighter yellow, and voice is different. Typical song is a short burst that starts off as a dry rattle and then morphs into airy squeaking. Inhabits humid forest and sometimes joins mixed species flocks.
Eastern Subalpine Warbler
Curruca cantillans
A small, slim warbler with a long tail. Breeding males are distinctive, with gray upperparts contrasting with a puffy rufous throat and breast, and a bold white moustache mark. Female and non-breeding males resemble a washed-out version of the breeding male, with much less rufous below. Typically found in scrubby, dense bushy habitats, but also in more open woodland and savanna. Sings from the tops of bushes, giving a rattling and loud sequence of notes. The calls are dry “trkk” or "trk-tek" notes, which are also incorporated into the song. Very similar to Moltoni’s Warbler, and best separated by the call (single or subtly doubled notes rather than dry rattles); breeding male is also richer rufous below. Also very similar to Western Subalpine Warbler, but call is subtly different: Eastern’s is slightly softer and tends to have two syllables. Breeding males are separated visually from Western by having more white on the belly, a darker face, and a broader white moustache.
Black-throated Huet-huet
Pteroptochos tarnii
Fairly common but elusive; heard far more often than seen. Favors native temperate forest and adjacent shrubbery, especially bamboo. Feeds on the ground by scratching with its big feet in leaf litter, and runs very quickly and stealthily. Agitated birds can call loudly from middle level perches, cocking their tail. Nests in burrows, but can nest high up in tree hollows. Plumage distinctive, with pale eyering, dark slaty throat and breast, and rusty belly. No range overlap with Chestnut-throated Huet-huet.
