The bananaquit (Coereba flaveola) is a species of passerine bird of uncertain relation. It is tentatively placed in the tanager family, but classified as incertae sedis by other authorities such as the American Ornithologists Union. Its classification is debated, and it is often placed in its own family: Coerebidae. It has recently been suggested the bananaquit should be split into three species, but this has yet to receive widespread recognition. This small, active nectarivore is found in warmer parts of the Americas, and is generally common.

It is distinguished from other green toucans by its red rump and its song is a quasi, something nasal and repeated. Its name Aulacorhynchus comes from the Greek aulax which means furrow and rhunkhos which means beak. The epithet haematopygus comes from the Greek haima, which means blood, and pugus, which means rump.

The American flamingo (Phoenicopterus ruber) is a large species of flamingo closely related to the greater flamingo and Chilean flamingo. It was formerly considered conspecific with the greater flamingo, but that treatment is now widely viewed (e.g. by the American and British Ornithologists’ Unions) as incorrect due to a lack of evidence. It is also known as the Caribbean flamingo, although it is present in the Galápagos Islands. In Cuba, it is also known as the greater flamingo It is the only flamingo that naturally inhabits North America.

It is a fairly polytypic species with a relatively complex taxonomy. . Its name Synallaxis comes from the Greek sunallaxis = change, which was assigned by Vieillot (1818) referring to characters that merited recognition as a different gender. The epithet azarae was established in honor of the Spanish military engineer and naturalist Felix Manuel de Azara.

The green honeycreeper (Chlorophanes spiza) is a small bird in the tanager family. It is found in the tropical New World from southern Mexico south to Brazil, and on Trinidad. It is the only member of the genus Chlorophanes. The purplish honeycreeper (Chlorophanes purpurascens), a bird from Venezuela known only from the type specimen, is now thought to be an intergeneric hybrid between the green honeycreeper and either the red-legged honeycreeper or the blue dacnis.

The white-capped tanager (Sericossypha albocristata) is the heaviest but not the longest species of tanager, at a weight of 114 g (4 oz) and a length of 24 cm (9.5 in). This species is glossy black overall with a large white crown and a red throat (which is brightest in adult males). It occurs in Colombia, Venezuela, Ecuador and Peru at elevations of 1600–3200 m. It lives in humid forest in groups of up to 20 individuals. Flocks of these tanagers stay in tight formation, often foraging from tree to tree together. They may eat fruits, seeds, hymenoptera, and coleoptera.

This species is a very noisy and gregarious bird typical of the Andes that is strongly associated with oak forests (Quercus). Its name Melenerpes means black woodpecker and derives from the Greek roots melas = black and herpes = climber. The epithet formicivorus means that it eats ants and derives from the Latin roots formica = ant and vorus = that eats or devours.
