Hispaniolan Palm-Crow
Corvus palmarum
Endemic to Hispaniola. A large, all-black, gregarious species of pine woodlands, scrub, and palm savannahs; often found in flocks of up to fifty birds. Note this species’ relatively short, stout bill with extensive feathering on top. Compare with White-necked Crow, which has longer bill with less extensive feathering on top. Additionally, White-necked is a bit larger and has red (not dark) eyes. Vocalizations are predominantly a flat, harsh “raaah,” which is rather different from any of the various calls of White-necked Crow.
分类信息
The Hispaniolan palm crow was formally described in 1835 under the binomial name Corvus palmarum by the German naturalist Duke Paul Wilhelm of Württemberg. The species is monotypic: no subspecies are recognised. This crow was formerly considered to be conspecific with the Cuban palm crow (Corvus minutus).<p>Despite being sympatric with the white-necked crow (Corvus leucognaphalus) on Hispaniola, it appears to be more closely related to the fish crow (C. ossifragus) of the East Coast of the United States, as well as two smaller species, the Tamaulipas crow (C. imparatus) and Sinaloan crow (C. sinaloae) of Mexico, than the white-necked crow, which is more related to the Cuban crow (Corvus nasicus) and the Jamaican crow (Corvus jamaicensis), the other two Caribbean corvids.<p>The following cladogram is based on phylogenetic study of the Corvidae by Knud Jønsson and collaborators that was published in 2012.<p>The species was formerly considered to be conspecific with the Cuban palm crow (Corvus minutus).

The local name for the palm crow is cao in the Dominican Republic (where it is locally common, mainly in mountain pine forests and also around the area of Lake Enriquillo), which is onomatopoeic of the simple and repetitive call of this bird.

Saipan Reed Warbler
Acrocephalus hiwae
A relatively large plain brown reed warbler with a pale throat, a yellowish face, a darker cap and tail, and an absurdly long decurved bill. Found in areas of tall dense grasses, reed marshes, and scrubby thickets up to 400 meters of elevation. Song is a slow, loud reel of whistles, warbles, harsh “chak” notes, and trills. Call is a loud, offensive “tchak.” Often sings at night.

Bare-crowned Antbird
Gymnocichla nudiceps
Scarce and rather shy antbird of evergreen forest, second growth thickets, and overgrown plantations in humid tropical lowlands. Usually in pairs, on or near the ground, where often accompanies army ant swarms to capture prey flushed by the ants. Male is black with white wingbars with bright blue naked skin on crown and around eyes. Female is rusty brown overall with bright blue naked eyering.

Cassin's Vireo
Vireo cassinii
Fairly dull vireo, intermediate between Blue-headed and Plumbeous. Grayish-olive overall, but with yellowish flanks and greenish back. Note white spectacles contrasting with gray head and two whitish wingbars. Breeds in mixed coniferous forests, especially in mountainous areas; winters in Mexico. Often separable from Blue-headed and Plumbeous Vireos by range, but can overlap during migration and winter. Cassin's is less contrasty than Blue-headed, especially between the gray face and whitish throat, and the greenish back blends into the nape and crown. Some birds are best left unidentified.
