Rose-throated Tanager
Piranga roseogularis
Uncommon in tropical woodland and forest edge of Yucatan Peninsula, mainly at mid-upper levels where often quiet and overlooked easily. Usually seen singly or in pairs. Rather plain, despite the name. Grayish overall with a broken white eye-ring; male has a rose-pink throat and red wash to the crown, wings, and tail; on the female these areas are washed yellowish.

The rose-throated tanager is 16 cm (6.3 in) long and weighs 21 to 30 g (0.74 to 1.06 oz). The nominate male's crown and throat are deep rose and the rest of the body shades of gray. The folded wings and tail appear crimson. The female's crown and throat are yellow. The upper parts are yellowish olive and the underparts mostly pale gray to whitish. Its folded wings and tail are yellowish. P. r. tincta has the same color schemes as the nominate but is paler, and P. r. cozumelae is darker.
分类信息
American ornithologist Samuel Cabot III described the rose-throated tanager in 1846, having seen a pair in the Yucatán Peninsula and shooting the male. A 2019 genetic study using mitochondrial DNA showed that it was a basal (early offshoot) of a lineage that gave rise to the scarlet, hepatic, summer, western and flame-colored tanagers.<p>The rose-throated 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, the Cardinalidae.<p>The rose-throated tanager has three recognized subspecies, the nominate Piranga roseogularis roseogularis, P. r. tincta, and P. r. cozumelae.

分布与栖息地
The nominate rose-throated tanager is found in the northern, drier, part of Mexico's Yucatán Peninsula. P. r. tincta is found in the more humid southern part of the peninsula and in northern Guatemala and Belize. P. r. cozumelae is restricted to the islands of Mujeres and Cozumel off the east coast of the peninsula. The species primarily inhabits the edges of semi-humid and humid mature forest and the undergrowth of scrubby forest, although it sometimes is found in areas with scrub and only scattered trees. In elevation it ranges from sea level to 250 m (820 ft).

行为
The rose-throated tanager forages throughout most levels of the forest, in undergrowth, saplings, mid-level, and the canopy. In the last it often joins mixed-species foraging flocks. It has also been observed following army ant swarms. Details of its diet have not been published.<p>No information on the rose-throated tanager's breeding phenology has been published.<p>The rose-throated tanager's song is "a rich warbled 'whee chee cheer-el-chee cheer-el-cheu chee-el-chu...'". Calls include a nasal "rreh" and a mewing "myaaa".

Curl-crested Manucode
Manucodia comrii
A large, crow-sized bird of wooded habitats on the southeast islands. Black overall with blue iridescence on the shoulder, and purple on the flight feathers and tail. Note the distinctive, dorsally-flattened tail with folded tips and feathered bulge on the head. The only other manucode in range is Trumpet Manucode, but Curl-crested lacks the loose feathers around the neck. Similar size to Torresian Crow but Curl-crested has a dark eye. Song, a remarkable, descending series of hollow notes given while tilting backwards, then rolling its whole body up and over.
Peruvian Martin
Progne murphyi
Scarce, local, and poorly known large swallow of lowland deserts and coastal areas. Usually seen as singles or small groups, usually apart from other swallows. Often flies rather high overhead, soaring easily and swooping more powerfully than small swallows. At times perches on desert slopes above agricultural valleys. Male is wholly blue-black, while female is dusky grayish overall with blue-black back and wings. No other martins occur regularly within its range.
Western Bearded-Greenbul
Criniger barbatus
A big, chunky, relatively colorful rainforest greenbul. Mostly olive-green, with a reddish tail and a mostly gray head. The throat feathers are long and often puffed out; they are rich yellow in most of the range, but pale yellow in Nigeria. Found in the understory and at middle levels of rainforest and gallery forest. Usually in small, noisy groups that often join mixed flocks. Similar to Yellow-bearded Greenbul, but larger, with a puffier throat and some gray in the plumage. Similar to Red-tailed Greenbul, but larger, and never shows a pure white throat. Somewhat similar to Icterine Greenbul, but larger, and much darker on the breast and belly. The loud and distinctive call is a rising, two-part “truwa-treeeaa.”
