White-bellied Erpornis
Erpornis zantholeuca
Small, crested, yuhina-like bird, frequently seen as a part of mixed flocks in a wide range of forested habitats. Upperparts yellowish green, underparts dingy gray except for yellow undertail coverts and whitish throat. Forages mostly in the upper layers of vegetation, from which its loud “nay nay” call is often heard.
识别特征
In its coloration, morphology and acrobatic habits, this bird resembles a vireo quite a lot. However, it has a prominent crest like many yuhinas, which together with the unusual biogeography has served to obscure its true relationships for a long time. The crested head, back, wings and tail of this bird are olivaceous or golden brown while the underparts are white.<p>Erpornis possesses well-developed musculature for gaping or opening the bill forcefully and may use this to pry bark from trees to seek insects.
分类信息
Formerly placed in Yuhina and often still misleadingly called "white-bellied yuhina", it is the most distinct member of this "genus" in its obsolete paraphyletic delimitation. It is by no means closely related to the Timaliidae (Old World babblers), where most of the former members of Yuhina are still placed. The Timaliidae are members of the superfamily Sylvioidea in infraorder Passeri, whereas the erpornis is the closest relative of the vireos (Vireonidae), which are a more ancient lineage of songbirds. Indeed, it now is usually included in the Vireonidae as one of their few Old World representatives.<p>Several subspecies are recognised: E. z zantholeuca, E. z tyrannula, E. z griseiloris, E. z sordida, E. z canescens, E. z interposita, E. z saani and E. z brunnescens.

Hispaniolan Oriole
Icterus dominicensis
A sleek forest bird that sometimes ventures into gardens and parks in search of flowers and fruit; prefers areas with palms. The adult is distinctive—clothed in black except for patches of yellow on lower belly, shoulders, and rump. No similar species occur within its range. Immatures are muddled yellow, orange, and olive, developing adult plumage over the course of a year. This plumage resembles that of female and young Baltimore Orioles, a scarce migrant and winter visitor to Hispaniola. Similarly attired Baltimore Orioles can be distinguished by their orange underparts and white wingbars. The song is a rapid jumble of squeaky and metallic notes. Calls include a buzzy “jrrrt” and a metallic “zhwee.”
Swainson's Spurfowl
Pternistis swainsonii
A large brown francolin with some darker streaks, dark blackish legs, and a distinctive bare red face and throat. It frequents grasslands and savannas where it is bold and conspicuous, standing on open branches and termite mounds to call its loud screeching “kreeeeet-kreeeeet-kreeeet” call at dawn and dusk. Red-necked Francolin differs by having red legs and feet, by often having white plumage on the underparts or face (depending on the race), and by preferring thickets and forest to open habitats.
Chestnut-backed Antbird
Poliocrania exsul
Medium-sized antbird with pale blue facial skin. Look for warm brown back and gray head; males have entirely gray body, females brown. Frequently flicks tail down and slowly raises it back up. Sticks to the understory in mature forest, where it can be difficult to get a clear view. Usually in pairs. Distinctive song: two or three whistles, the last note dropping in pitch.
