Blue-and-yellow Macaw
Ara ararauna
Enormous parrot with a long, pointed tail. Unmistakable: cerulean upperparts and golden-yellow underparts with a white face and black patch on the throat. Could only be confused with Blue-throated Macaw, which is rare and local in Bolivia only and has a more extensive blue throat and a less extensive white face. Found in lowland rainforests and savannas from eastern Panama to Brazil, often in more open habitats than other macaws. Usually found in pairs, which fly together and perch in the canopy. Can gather in small groups, especially at fruiting trees or clay licks. Nests in cavities. Listen for raucous calls, typical of large macaws.
识别特征
These birds can reach a length of 76–86 cm (30–34 in) and weigh 0.9–1.5 kg (2–3 lb), making them some of the larger members of their family. They are vivid in appearance with bright aqua blue feathers on the top of their body except for the head, which is lime colored. The bottom, however, is a rich deep yellow/light orange. Their beak is black, as well as the feathers under their chin. Its feet are of a gray color, save for black talons. The bird has white skin, with its face having nearly no feathers beside a few black ones spaced apart from each other forming a striped pattern around the eyes. The irises are pale light yellow.<p>Blue-and-yellow macaws can live from 30 to 35 years in the wild, and reach sexual maturity between the ages of 3 and 6 years.<p>Little variation in plumage is seen across the range. Some birds have a more orange or "butterscotch" underside color, particularly on the breast. This was often seen in Trinidad birds and others of the Caribbean area. The blue-and-yellow macaw uses its powerful beak for breaking nutshells, and for climbing up and hanging from trees. As well as nuts, it will also feed on seeds, fruits, vegetable matter, bark and leaves, also insects, snails and small animals.
分类信息
The blue-and-yellow macaw was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his Systema Naturae. He placed it with all the other parrots in the genus Psittacus and coined the binomial name Psittacus ararauna. This macaw is now one of the eight extant species within the Ara genus, first proposed in 1799 by the French naturalist Bernard Germain de Lacépède. The genus name is from ará meaning "macaw" in the Tupi language of Brazil. The word is an onomatopoeia based on the sound of their call. The specific epithet ararauna comes from the Tupi Arára úna meaning "big dark parrot" for the hyacinth macaw. The word ararauna had been used by the German naturalist Georg Marcgrave in 1648 in his Historia Naturalis Brasiliae. The species is monotypic: no subspecies are recognised.

分布与栖息地
This species occurs in Panama, Trinidad and Tobago, Colombia, Suriname, French Guiana, Venezuela, Guyana, Peru, Brazil, Bolivia, Ecuador, and Paraguay. The range extends slightly into Central America, where it is restricted to Panama. While most breed in rural and forested areas, small numbers breed in urban cities such as Rondonópolis, Mato Grosso, Brazil, nesting in dead palms planted for ornamental purposes alongside city roads. Although they were nearly wiped out in Trinidad due to human activity during the 1970s, a recent programme of reintroduction has proved successful. Between 1999 and 2003, wild-caught blue-and-yellow macaws were translocated from Guyana to Trinidad, in an attempt to reestablish the species in a protected area around the Nariva Swamp; despite this, the IUCN still lists them as extirpated from the country. A small breeding population descended from introduced birds is found in Puerto Rico, and another has inhabited Miami-Dade County, Florida, since the mid-1980s.

保护状况
The blue-and-yellow macaw is on the verge of being extirpated in Paraguay, but it still remains widespread and fairly common in a large part of mainland South America. The species is therefore listed as Least Concern by BirdLife International. Its wild population has not been quantified but is believed to be above 10,000 individuals and is in decline. It is listed on CITES Appendix II, trade restricted.

White-eared Jacamar
Galbalcyrhynchus leucotis
Chunky-looking bird with a small head and a larger bill than other jacamars, recalling a kingfisher. Chestnut-colored overall with a pinkish-red bill. Occurs in humid upland and seasonally flooded forests, where it is most often seen flycatching from exposed branches, often in small groups. The song is a high, whistled “péeeuh- péeeuh- péeeuh- péeeuh.”
Little Crake
Zapornia parva
Tiny, with long wings and a short greenish bill with a small red base. Face and underparts are plain slaty gray on male, and buffy to whitish on female and juvenile. Adults have plain flanks and boldly barred undertail coverts. Juvenile has barred flanks; compare to similar Baillon’s Crake. Breeds in freshwater wetlands with extensive emergent vegetation, and spends the non-breeding season in a wide range of marshy habitats. Often favors deeper-water aquatic plant stands than other rails and crakes, clambering about nimbly amongst the vegetation. Usually retiring and rarely seen, but can be confiding. Males give a long song that starts with a series of “qwek” notes that eventually accelerates and tapers off; females respond with a descending trill with a similar quality.
White-bellied Emerald
Chlorestes candida
Small and rather plain hummingbird of tropical lowland forest and edge. Feeds low to high, often at edges and out in clearings. Both sexes look ‘female-plumaged,’ with green upperparts, white underparts; reddish color on base of bill can be difficult to see. Tail drab greenish with faint dusky band near tip. Lacks bold white tail corners of other small hummingbirds, such as female Ruby-throated.
