Painted Redstart
Myioborus pictus
This unmistakable warbler is found in canyons and mountainous areas with oaks and pines. Striking plumage: black with large white wing patch and red belly. Tail is often fanned and flashed while foraging, revealing bold white outer tail feathers. Very active, usually flitting around in the lower to mid-levels of trees. Listen for a musical warble with repeated “chewee” notes. Call is similar to Pine Siskin but less wiry. Primarily a Mexican species, occurring as far south as northern Nicaragua. Breeding range barely extends into the southwest U.S.
识别特征
The painted redstart is the largest species of Myioborus, measuring 5.1–5.9 in (13–15 cm) in length, 8.3 inches (21 cm) in wingspan and having a weight of 0.3–0.4 oz (8.5–11.3 g).<p>The sexes are the same in plumage, though males average slightly larger than females. The adult is mostly black, with a bright red lower breast and belly, large white wing patches, white outer tail feathers and white crescents below its eyes. The bill and legs are blackish.<p>The juvenile painted redstart lacks the red belly and glossy black plumage of the adult. It is brownish-gray overall, with a paler belly and undertail coverts, and a pale cream or buff tinge to its wing patches. The young have a deep yellow-orange mouth lining.<p>Painted redstarts are unusual amongst birds, and especially amongst warblers, in that the female is capable of singing just as well as a male, and during spring courtship a pair will often bond by singing together.
分类信息
When he first described the species in 1829, naturalist William John Swainson assigned it to the genus Setophaga — the same genus as that of the American redstart — where it remained for nearly a century and a half, though one naturalist placed it in the Old World flycatcher genus Muscicapa during that time. By the mid 1960s, researchers recommended that it be moved to its current genus, Myioborus, based on various similarities with the other whitestarts. The painted redstart is the sister taxon to all the other species in the genus Myioborus.<p>There are two subspecies, which differ only slightly in appearance:

分布与栖息地
Painted redstarts are common in open oak woodlands and canyons at heights between 1,500–2,500 m (4,900–8,200 ft) in Central America and Mexico, ranging as far north as the Madrean sky islands and Mogollon Rim in Arizona and New Mexico and Big Bend National Park in Texas; they are thought to be wholly insectivorous. During the summer and winter, these birds may venture as far south as Nicaragua. In 2010, a painted redstart was found further north in California than had ever been recorded, in Auburn, CA, east of Sacramento. In 2013, one was observed in Berkeley, CA.

Black-crowned White-eye
Zosterops atrifrons
A small green songbird with a bold white eye-ring, a black forehead, and whitish underparts except for a yellow throat and undertail. Juveniles duller, with less black on forehead. Found in groups, often within mixed-species flocks, in forests, edges, and cultivated areas in lowlands and foothills. Separated from Lemon-bellied White-eye by whitish belly, and from Warbling and Sulawesi White-eyes by black forehead on Black-crowned White-eye. Song variable, comprising short, high-pitched warbles. Also gives chattering and twittering notes as well as “tzew” and repetitive “titititititit” trill calls.
Philippine Dwarf-Kingfisher
Ceyx melanurus
A tiny kingfisher of lowland forests, often near streams. Overall orange, brighter on the underparts and face, with bright red bill and legs, a white throat, belly, and mark behind the cheek, and black stripes down the side of the back. Note the pinkish-purple tinge to the head and chest. Birds on Luzon have a darker wing and a bluish ear. Somewhat similar to Dimorphic Dwarf-Kingfisher, especially when seen from the front or below, but Philippine lacks the bright blue head and back. Voice is a rather sharp, high-pitched note, “tsreek.”
Blue-winged Macaw
Primolius maracana
Fairly small macaw with a bare white face that contrasts with its dark bill. It has a small red forehead, which can be quite difficult to see, a blue crown, and a red belly. The flight feathers are striking blue. Usually seen in pairs or small groups at forest edges, palm groves, and open woodlands. The flight call is a mellow “graaaa.”
