Metallic-green Tanager
Tangara labradorides
Small tanager found in Andean subtropical zone from Colombia to Peru. Unique seafoam green color, often appearing fairly dull. Greener than Golden-naped Tanager and lacks the spangled appearance of Beryl-spangled Tanager. Also note small black mask, black nape, and black wings with thin green edges. Buffy undertail coverts and vent only visible at some angles. Sexes alike. A fairly common member of mixed flocks from around 1,300–2,300 m, in cloud forest and edges.
分类信息
The blue-and-black tanager was first described as Tanagra (Aglaia) labradorides by Auguste Boissonneau in 1840 on the basis of a specimen from Santa Fe, Colombia. The generic name Tangara comes from the Tupí word tangara, meaning dancer. The specific name labradorides is from the French pierre de Labrador (feldspar), and the Ancient Greek -ides, meaning resembling, referring to the species' metallic blue-green color, which resembles that of feldspar. Metallic-green tanager is the official common name designated by the International Ornithologists' Union (IOC).<p>The metallic-green tanager is one of 27 species in the genus Tangara. It was previously thought to form a species group with the blue-browed and golden-naped tanagers. However, phylogenetic studies have shown that the golden-naped tanager is only distantly related to the other two species in the group. Its relation with the blue-browed tanager is also unclear, as some studies have shown the metallic-green tanager to be sister to the blue-browed tanager, but others have found this grouping to be paraphyletic.<p>There are two recognized subspecies of the metallic-green tanager. DNA studies have shown that the rate of divergence between in nucleotide sequences between the two subspecies is higher than that of several other tanagers currently recognized as distinct species.

Lesser Antillean Saltator
Saltator albicollis
A small to medium-sized, olive-colored inhabitant of thickets, scrub, and other low dense habitats. A distinctive species with a stout black-and-yellow bill, a pale throat, and a pale eyebrow. No similar species occur within its range. Its song is a series of loud musical notes that rise and fall. Call notes include faint “tsi” and sharp “chink.”
Black Tinamou
Tinamus osgoodi
Large, rare tinamou found in cloud forest along the east slope of the Andes. It is uniformly sooty gray, much darker and plainer than Gray Tinamou. Rusty lower underparts are hard to see in the field. Like other forest tinamous, it is far more likely to be heard than seen. Vocalizations include a low, drawn out coo, like a dove’s but longer, and a series of low, modulated whistles.
American Herring Gull
Larus smithsonianus
Common and widespread large gull found throughout North America. Adults have a fairly pale gray back, pale eye, and dull pinkish legs. Takes four years for immatures to progress from mostly brown to fully white and gray adult plumage; intermediate plumages are often mottled and messy. Usually shows a dull pinkish base to the bill by the first winter, and develops a pale eye by the second winter. Some immature birds can fade to almost white, especially in their first or second summer, but they always show darker wingtips. Occurs inland and along the coast, frequenting fishing boats, beaches, lakes, and landfills. Often forms large flocks with other gulls.
