Glow-throated Hummingbird
Selasphorus ardens
Tiny, poorly-known hummingbird with extremely limited range in western Panama. Males are greenish above with rusty flanks, a pinkish-red throat, and a white collar. Note dark tail with rufous edging. Compare with male Scintillant Hummingbird, which has a mostly rufous tail and an orange throat. Female Glow-throated has a speckled throat, buffy flanks, and greenish upperparts. The central tail feathers are greenish while the rest of tail is rufous with a black band and buffy tips. Female Scintillant is very similar and may not be separable in the field, but has more extensive rufous edges on central tail feathers. Found at the edge of montane forest from around 750–1,800 m.
识别特征
The glow-throated hummingbird is about 7 cm (2.8 in) long. Both sexes have a short, straight, black bill. The adult male has bronzy green upperparts and the tail feathers are black with rufous edges. Its gorget is pinkish red with a white foreneck below it. The center of the breast and belly are also white and the rest of the underparts buffy to cinnamon with green spangles and buffy white undertail coverts. Adult females are also bronzy green above. Their central tail feathers are green; the rest have rufous bases, a black band near the end, and deep buffy tips. The throat is pale buff with grayish speckles and the rest of the underparts are like the male's. Immature birds resemble adult females but have rusty fringes on their head and nape feathers and more green on the tail.

分布与栖息地
The glow-throated hummingbird is found only in west-central Panama's Chiriquí and Veruagas provinces. It was historically found more widely in Serranía de Tabasará but since the early 20th century is known only from Cerro Colorado and Cerro Flores in Chiriquí and Cerro Tute and the Santa Fé district in Veraguas. There are unsatisfactory sight records from the Azuero Peninsula, where its presence is considered hypothetical. It inhabits the edges and clearings of Talamancan montane forest at elevations between 750 and 1,800 m (2,500 and 5,900 ft).

The movements of the glow-throated hummingbird, if any, are unknown.<p>Nothing is known about the foraging behavior or diet of the glow-throated hummingbird. Both are assumed to be similar to that of its close relative, the scintillant hummingbird (S. scintilla). That species, like most hummingbirds, feeds on nectar from flowers and on small insects.<p>Nothing is known about the glow-throated hummingbird's breeding phenology.<p>As of July 2022 neither the Cornell Lab of Ornithology's Macaulay Library nor xeno-canto have any recordings of the glow-throated hummingbird's vocalizations.

Gray-winged Robin-Chat
Sheppardia polioptera
Medium-sized robin with orange underparts and an olive-brown back. The tail is uniformly rufous, lacking the dark center of a typical robin-chat. There is some geographical variation, with the western birds showing a black cap and the eastern birds a gray one. Found in the undergrowth of various forest types at low and middle elevations. Shy and retiring. The song is a highly variable mix of notes which usually includes imitations of other bird species. Similar to akalats, but separated by its white eyebrow.
Masked Shining-Parrot
Prosopeia personata
A distinctive large bright green parrot with a black face and a rough-edged yellow chest and belly. Occurs in a variety of habitats. Black face and yellow chest separate it from the similarly sized Crimson and Red Shining-Parrots. Voice is typical of parrots, including a variety of nasal “erh” and “grrraah” calls.
Common Snipe
Gallinago gallinago
Squat, cryptically-plumaged shorebird with a very long bill. Inhabits a wide range of wetland habitats, from damp meadows to saltmarshes. Mostly inconspicuous, feeding in muddy ground by probing with its bill, usually near reeds or other grassy cover. Often not seen until flushed, when it usually rises from fairly close range with a rough rasping call. Breeding birds are more conspicuous, perching on fence posts. In display flight, birds stoop from high overhead and produce a pulsating, bleating sound from air passing through their fanned tail. In Asia, beware of extremely similar Pin-tailed, Swinhoe's, and Latham's Snipes, all of which lack the white trailing edge of Common and have a slower, less erratic flight.
