Eastern Orphean Warbler
Curruca crassirostris
Plain but subtly attractive medium-sized warbler. Adult is gray with a black head and a white throat. Female has a less contrasting head pattern than the male. Younger birds are browner with a faded-looking version of the adult’s head pattern. Visually very similar to the Western Orphean Warbler, but the black on the head is more cleanly cut off from the gray of the back on Eastern Orphean Warbler. Also note the comparatively cleaner-looking belly on Eastern Orphean. Breeding ranges do not overlap. Breeds in open forests from which it delivers its song in phrases with an almost thrushlike warbling melody. Non-breeding habitats include open scrubby habitats, such as thornscrub and semidesert.
识别特征
The eastern Orphean warbler (Curruca crassirostris) is an Old World warbler of the genus Curruca. This species occurs in summer around the Mediterranean, through the Balkans via Turkey, the Caucasus and surrounding regions to Central Asia. It is migratory, wintering in sub-Saharan Africa. At 15–16 cm length—somewhat larger than a blackcap—this is one of the largest species of typical warblers. The adult males have a plain grey back. The bill is long and pointed and the legs black. The male has a dark grey head, black eye mask, and white throat. The iris is white. Females and immatures have a paler head and reddish underparts; their grey back has a brownish tinge. The iris is dark in young birds. It is difficult to visually distinguish from the Western Orphean warbler. The song is a series of warbling liroo-liroo and scolding notes. Its song is more varied than that of the western Orphean warbler, approaching the Nightingale in richness. These small passerine birds are found in open deciduous woodland. 4–6 eggs are laid in a nest in a bush or tree. Like most "warblers", the eastern Orphean warbler is a nectarivore.

Red-headed Trogon
Harpactes erythrocephalus
A brightly-colored bird of dense evergreen forests, usually seen perched quietly on a mid-story perch. Varies in coloration throughout its range but always follows the same general color scheme: male has a dark red head and belly, a brown back, and barred black-and-white wings. Female has a more faded-red belly and a brown head. Both sexes, when seen from below, have a sharply contrasting and graduated black-and-white tail pattern. Sluggish and typically stationary and difficult to see; listen for its high-pitched gulping hoots.
Blackish Cuckooshrike
Edolisoma coerulescens
A medium-sized bird of lowland and foothill forest. Slender, with a medium-length bill and tail. The male is entirely black with some blue gloss on the back and crown. Female is slaty-gray with a blackish face and tail. Female is similar to Black-bibbed Cuckooshrike, but larger and more uniformly dark gray in color. The black male differs from other black birds like Philippine Fairy-Bluebird and Asian Glossy-Starling by its dark rather than red eye. Song is a forceful, descending whistle, “tiiuuuu!”
White-throated Thrush
Turdus assimilis
Widespread large thrush of woodland and forest, mainly found in foothills and highlands, but some wander to lowlands in winter. White collar across front of neck can be difficult to see. Populations north of Isthmus of Tehuantepec and in highlands to the south are rather dull, gray-brown overall with a dull pale greenish-yellow bill and pinkish legs. Birds on Atlantic slope south of Isthmus look very different: slaty blackish above with yellow bill, eyering, and legs.
