Inagua Woodstar
Nesophlox lyrura
A small, long-tailed hummingbird of wooded and scrubby habitats including gardens; most often found feeding on flowers or at hummingbird feeders. Note the male’s iridescent purple throat and forehead plus its long, forked tail. On females, note the orange sides and tail edges. This species is unique within its range. Calls include a sharp, metallic “tit” or “tit-it”; often given in a series, sometimes quite rapidly. Males also make a metallic sound with their tail during display flights.
识别特征
The Inagua woodstar is 7.8 to 8.2 cm (3.1 to 3.2 in) long and weighs 2.1 to 2.7 g (0.074 to 0.095 oz). Both sexes have a short, slightly decurved, black bill and a small white spot behind the eye. The male's forehead and gorget are glittering reddish purple. Its upperparts are iridescent green, the breast whitish, and the belly mixed rufous and green. The tail is very deeply forked. Its central feathers are green and the others have cinnamon-rufous inner webs. The outermost feathers are lyre-shaped. Females have dull green upperparts, pale gray chin and throat with small green spots, a whitish chest, and a rufous belly. Their tail is rounded; the central feathers are green and the rest cinnamon with a wide black band near the end.
分类信息
The Inagua woodstar was originally treated as a subspecies of the Bahama woodstar (Nesophlox evelynae), which for a time was placed in the genus Calliphlox. Following a 2015 publication, the Committee on Classification and Nomenclature of the then American Ornithologists' Union recognized the Inagua woodstar as a separate species and the major worldwide taxonomic systems followed suit. A molecular phylogenetic study published in 2014 found that the genus Calliphlox was polyphyletic. Following that study and a 2017 publication, taxonomists moved the Inagua and Bahama woodstars into the resurrected genus Nesophlox.<p>The Inagua woodstar is monotypic.

分布与栖息地
The Inagua woodstar is found on Great and Little Inagua islands in the Bahama archipelago. It inhabits most of the landscapes of the islands with the probable exception of mangroves. These include dune scrub, freshwater riparian areas, and human-made parks and gardens.

行为
The Inagua woodstar is assumed to be sedentary but for movements in response to where flowers are blooming. However, there are a few records of vagrant Bahama woodstars in Florida and Cuba from before the split that were not identified at the subspecies level, so it is possible that some were of this species.<p>The Inagua woodstar forages for nectar at a variety of native and introduced flowering plants. Both sexes defend small territories around good nectar sources. In addition to nectar, the species also feeds on small insects captured by hawking from a perch.<p>The Inagua woodstar's breeding season has not been defined but seems to include October. It makes a tiny cup nest of plant fiber and spiderweb lined with soft fibers and covered with small pieces of bark. It generally places it within 1 and 3 m (3 and 10 ft) of the ground. Nothing else is known about the species' breeding phenology.<p>As of July 2022, neither the Cornell Lab of Ornithology's Macaulay Library nor xeno-canto have recordings of the Inagua woodstar's vocalizations. Its song is described as quiet and simple, "sounding like wet, squeaking shoes". It also makes "chip" calls.

Verdin
Auriparus flaviceps
Tiny, unique songbird with a sharply pointed bill. Mostly plain gray with a yellow head. Small rufous patch on shoulders is sometimes visible. Juveniles lack the yellow head; note bill shape to help separate from Lucy's Warbler or Bushtit. Forages solo or in pairs in scrubby arid habitats, especially mesquite. Occasionally visits hummingbird feeders for nectar; primarily feeds on insects.
Finsch's Euphonia
Euphonia finschi
Small finch of forest canopy; often seen perched on bare branches. Males have yellow forecrown and belly contrasting with dark throat; females mostly dull yellow and green. Usually in pairs or small groups; may sit motionless for long periods before flying off into the distance. Found in a variety of forest types including coastal and savanna forest; usually in the canopy and at fruiting trees. Frequently heard call a plaintive, doubled whistle. Male is very similar to Purple-throated Euphonia but more richly colored below; female is similar to Violaceous Euphonia and best distinguished by attendant males.
Wedge-tailed Grass-Finch
Emberizoides herbicola
Among all the streaky sparrowlike birds of open grassy habitats in its range, Wedge-tailed Grass-Finch is unique with its long spiky tail. Also note the stout yellow bill. Otherwise rather pale brown overall, clean buffy below with thick black streaks on back. If seen well, back and wings are suffused with a yellow tone. Similar to Lesser Grass-Finch, but is larger, darker and lacks a white throat. Look for singles or pairs in grassy or brushy fields, often announcing their presence with a chip note.
