Flame-colored Tanager
Piranga bidentata
Fairly common in oak and pine-evergreen forests in foothills and highlands; a few descend in winter to lowlands of west Mexico. Forages mainly at middle to upper levels where often quiet and overlooked easily. Note the bold white wingbars, big white tertial and tail spots, and dark streaks on back. Male flame-orange in west Mexico and deeper orange-red in east Mexico and Central America. Female told from female Western Tanager by gray bill, bolder white wing markings, and streaked back. Calls and song very like Western Tanager.
识别特征
The flame-colored tanager is 18 to 19 cm (7.1 to 7.5 in) long. The nominate weighs 33.3 to 39.4 g (1.17 to 1.39 oz) and P. b. flammea 32 to 48.4 g (1.13 to 1.71 oz). The nominate male's head and underparts are red-orange becoming yellower towards the vent area. It has a brown patch below the eye from the bill to behind the eye. The mantle and back are dusky orange with an olive tint; the rump is paler with little or no streaking. The female has a similar pattern but its head and underparts are yellow and the back is olive with black streaks. The male P. b. flammea is a paler red-orange than the nominate. P. b. sanguinolenta is also similar to the nominate but the head and underparts are bright red to orange-red. P. b. citrea is paler and more orange below compared to the nominate.

English naturalist William John Swainson described the flame-colored tanager in 1827 from material collected by William Bullock and his son from a specimen from Temascaltepec in Mexico. French ornithologist Frédéric de Lafresnaye described Piranga sanguinolenta as a separate species in 1839, though the two were generally regarded as conspecific by the end of the 19th century.<p>A 2019 genetic study using mitochondrial DNA showed that the flame-colored tanager was the sister taxon of the western tanager (P. ludoviciana).<p>The flame-colored tanager and the other species of genus Piranga were originally placed in the family Thraupidae, the "true" tanagers. Since approximately 2008 they have been placed in their current family.<p>The flame-colored tanager has four recognized subspecies, the nominate Piranga bidentata bidentata, P. b. flammea, P. b. sanguinolenta, and P. b. citrea.

分布与栖息地
The subspecies of flame-colored tanager are found thus:<p>The flame-colored tanager inhabits the canopy of humid montane forest and large trees in non-forested areas such as pastures, coffee plantations, and gardens. In much of its range it is also found in open oak and pine-oak woodlands. It is generally a bird of the mountains but can be found near sea level in Guatemala. In Mexico it ranges from 800 m (2,600 ft) to treeline and in Panama lives at 1,200 m (3,900 ft) and higher. On the Caribbean slope in Costa Rica it ranges from 1,850 to 2,850 m (6,070 to 9,350 ft) and on the Pacific slope can be found as low as 900 m (3,000 ft). It is largely resident but may seek lower elevations in winter. Those found in the United States are pre- and post-breeding wanderers and rarely nesters, with several sightings and one specimen collected in Texas.

行为
The flame-colored tanager's diet is small arthropods and a variety of berries. It usually forages alone or in pairs, but will join mixed-species foraging flocks. Though it usually hunts through the tops of trees, it also sallies out for flying insects and sometimes descends to near the ground to glean fruit. It has been reported ambushing swarms of army ants (Eciton burchellii) carrying wasp larvae and pupae, and eating both ant and wasp. The predatory status of this bird has been documented to prey on certain types of arthropods found within the Sonoran canopy as it dives to catch insects and often those being carried by army ants.<p>The flame-colored tanager's nest is an open cup of fairly coarse material lined with fine grass; it can be placed in dense foliage or in isolated trees or shrubs in a more open area. Breeding has been documented in April and May.<p>The flame-colored tanager's song is similar to a vireo's, a "rich, musical ... 'chewee-very-vire, chewee-very-vire-very, cheery-cheweea ...'". Its call is "per-dick" or "chi-dick".

Gray-cheeked Nunlet
Nonnula frontalis
Rare and unobtrusive in forests and woodlands, typically with dense understory. Distinctive within limited range. Rather plump with large, slightly decurved bill. Brownish overall with warmer rufous crown, gray cheek, and tawny throat. Also note pinkish eyering. Sexes similar. Perches stolidly in the lower to middle levels; typically singly or in pairs.
Rufous-rumped Foliage-gleaner
Neophilydor erythrocercum
A medium-sized bird, brownish above and pale buff below, with a bright rufous rump and tail and a distinctive buffy line behind the eye. Found in tall rainforest, where it occurs mainly in the midstory and canopy, but occasionally in the understory. Will follow mixed species flocks at all levels. Feeds on insects and forages actively, often investigating dead leaf clusters and other accumulations of detritus. Song is a short, weak series of squeaking notes that fades away; call is a hard doubled note. Most similar to Rufous-tailed Foliage-gleaner but somewhat larger and more likely to occur at lower levels in the forest; both tail and rump are rufous in Rufous-rumped.
Martinique Thrasher
Ramphocinclus brachyurus
A ground-feeding denizen found very locally in wooded ravines and valleys with thick low vegetation. It somewhat resembles both Brown and Gray Tremblers in shape but it has bold white underparts and a dark red eye, which the tremblers lack. Like the tremblers, it tends to droop its wings, but does not often cock its tail. Most commonly heard call a short raspy note, often given in series.
