White-eyed Vireo
Vireo griseus
A small, active vireo of dense shrubbery. Distinctive yellow spectacles contrast with gray head. Also look for two white wingbars, green back, and yellow sides. Adults have white eyes; juveniles have darker gray eyes. Occurs in dense second growth, forest edge, and thickets; more often heard than seen. Listen for the variable, scratchy "chick-burio-chick" song. Primarily occurs in the southeastern U.S., wintering into northern Central America and the Caribbean. Compare with duller olive Thick-billed Vireo in the Caribbean, and plainer Bell's Vireo in the U.S. and Mexico.

The white-eyed vireo was described by the French polymath Georges-Louis Leclerc, Comte de Buffon in 1780 in his Histoire naturelle des oiseaux. The bird was also illustrated in a hand-coloured plate engraved by François-Nicolas Martinet in the Planches Enluminées D'Histoire Naturelle which was produced under the supervision of Edme-Louis Daubenton to accompany Buffon's text. Neither the plate caption nor Buffon's description included a scientific name but in 1783 the Dutch naturalist Pieter Boddaert coined the binomial name Tanagra grisea in his catalogue of the Planches Enluminées. Buffon specified that his specimen had come from Louisiana, but in 1945 the type locality was restricted to New Orleans. The white-eyed vireo is now placed in the genus Vireo was introduced in 1808 by the French ornithologist Louis Pierre Vieillot. The word vireo was used by Latin authors for a small green migratory bird, probably a Eurasian golden oriole but a European greenfinch has also been suggested. The specific epithet griseus is Medieval Latin for grey.<p>Six subspecies are recognised:<p>The northern subspecies, V. g. noveboracensis, occupies most of the range of this species and is fully migratory. This sub-species is larger and has more brightly colored plumage than all other subspecies.<p>The resident southeastern coastal plain race, V. g. griseus is a slightly smaller and duller colored subspecies. It does not typically migrate out of its breeding range in the winter.<p>The resident Florida Keys race, V. g. maynardi, is greyer above and whiter below, and the south Texan V. g. micrus is like a smaller maynardi.<p>V. g. bermudianus is endemic to Bermuda, where it is known as the Chick of the Village. This has shorter wings and a duller plumage. Along with other endemic and native Bermudian birds, it was threatened with extinction following the loss of 8 million Bermuda cedar trees in the 1940s, and is now quite rare. This species is listed under the Bermuda Protected Species Act 2003.

分布与栖息地
It breeds in the eastern United States from New England west to northern Missouri and south to Texas and Florida, and also in eastern Mexico, northern Central America, Cuba and the Bahamas. Populations on the US Gulf Coast and further south are resident, but most North American birds migrate south in winter. This vireo frequents bushes and shrubs in abandoned cultivation or overgrown pastures.

Red-vented Malimbe
Malimbus scutatus
A striking black-and-red forest malimbe with a unique red patch on the vent. Male has a black face and a red crown, neck and breast; female only has red on the breast. A fairly common resident within its range, found in pairs in the middle levels and canopy of tall primary and secondary lowland forest, farmbush, cultivation, and clumps of trees near villages. Occasionally joins flocks, sometimes with other malimbes, and gleans leaves and thin twigs in the manner of a tit. Calls include a hard “tchuk” and also a cicada-like “zee-zee-zee.” Other similar-looking malimbes lack the red vent patch.
LeConte's Thrasher
Toxostoma lecontei
The palest thrasher; entirely light tan with whiter throat. Undertail coverts peach colored. Bill dark and strongly curved; eye dark. Found in dry flat deserts with open ground, often seen running between patches of low bushes. Shy and difficult to see well. Song similar to other thrashers, often with doubled or tripled notes; tends to be rather slow.
Southern Martin
Progne elegans
Large swallow with pointed wings and slightly forked tail. Males are deep iridescent purple; females are also entirely dark, but are brownish below, with faint scaling. Migrates within South America; at some times of year, occurs with other very similar martin species, making identification difficult. Females lack the light belly of similar Purple and Gray-breasted Martins; males essentially indistinguishable from Purple Martin.
