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.

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.

Costa Rican Warbler
Basileuterus melanotis
Small understory warbler, dull buffy-brown overall. Bold black stripes on head, including cheek patch. Sexes alike. Recalls Worm-eating Warbler but plumper with longer tail; face pattern different. Found in pairs or small flocks moving through the forest understory. Often with a mixed-species flock. Energetic twittering song is a good clue that there’s a flock nearby.
Chapman's Antshrike
Thamnophilus zarumae
Attractive antbird restricted to arid Andean slopes in southwestern Ecuador and northwestern Peru. Male is gray and white with a barred breast, back, and tail, streaked face and throat, black crest, and buffy belly. Female is brown and buff with a darker crest, black-and-white streaked face, and very faint barring on the breast. No overlap with the similar Barred Antshrike. Inhabits dry forest and scrub. Jaunty song starts with a fast series of clucks and ends with a few higher-pitched notes followed by lower-pitched notes.
Townsend's Shearwater
Puffinus auricularis
Endangered, small black-and-white shearwater, endemic to Mexico. Found around Socorro Island mainly from November to May, and rarely offshore between Jalisco and Oaxaca. It is usually found with feeding flocks of other shearwaters, boobies, and terns. Flight is fast and strong, wheeling fairly high in strong winds. Blackish above and white below with blackish undertail coverts, fairly long tail, and white patches or saddlebags that wrap up around the base of the tail. Similar species: Black-vented Shearwater is dark brownish above without the strong black cap of Townsend’s.
