Square-tailed Drongo-Cuckoo

Surniculus lugubris

A small, slim black cuckoo rather similar to Black Drongo but smaller, with a curved bill. Adult black with white bars in the undertail, shorter-tailed juvenile deep blackish gray with bright white dots in wings and flanks. Rather sedentary and difficult to see in tangled vegetation of scrubby and edge habitats in lowland and foothill forests. Song a loud, vibrant, rapid series of ascending hoarse whistles.

识别特征

It can be easily distinguished by its downcurved beak and the white barred vent and outer undertail, and the tail only notched with slightly flared tips. In flight a white wing-stripe is visible from below. It is a brood parasite on small babblers. It is not known how or whether the drongo-like appearance benefits this species but it is suspected that it aids in brood-parasitism just as hawk-cuckoos appear like hawks.<p>The square-tailed drongo-cuckoo was formerly considered conspecific with the fork-tailed drongo-cuckoo (together known as the Asian drongo-cuckoo), but vocal and morphological differences suggested that the species should be split. That treatment is followed here.

Olive-bellied Sunbird

Olive-bellied Sunbird

Cinnyris chloropygius

Small sunbird in which males are colorful, green and red, and females drab brownish. Males have yellow shoulder tufts that are usually hidden. Found in forest clearings, along forest edge, and in woodland, moist savanna, gardens, and brush. Often feeds on low flowers. The song is a quick, high-pitched jumble. Similar to Tiny Sunbird, but larger, with a shorter and more curved bill, and males are less bluish above. Male very similar to male double-collared sunbirds, but lacks blue or purple band above the red on the breast.

Gray Catbird

Gray Catbird

Dumetella carolinensis

Medium-sized songbird with a smooth gray body, black cap, and rusty-red undertail coverts. Sexes alike. Occurs in shrubby habitats, especially thickets or second-growth at the edge of forest, often near water. Usually quite skulking, but sometimes pops up conspicuously, especially when singing. Occasionally visits feeders, especially for suet. Listen for complex, jumbled song, which often includes mimicry of other species.

Crimson-hooded Manakin

Crimson-hooded Manakin

Pipra aureola

Small, plump bird of swampy forest understory. Stunning adult male is rich red on head and breast, with black upperparts and white eyes. Females and young males are dull greenish, often suffused with yellow especially on the throat, and have pale gray to whitish eyes. Found in flooded forests, including tall second growth and abandoned plantations, near large rivers and in coastal areas. Feeds on fruit which it takes in short sallies, like other manakins. Often common but generally inconspicuous, even when displaying. Male display vocalization is a single loud, whining note, strongly descending and virtually identical to calls of Wire-tailed and Band-tailed Manakins; multiple birds often give the note simultaneously creating a harmonic effect. Adult males are unmistakable; females and young males are distinguished from other manakins by bulky shape and pale eyes.
