Atoll Fruit-Dove
Ptilinopus coralensis
A colorful dove, mostly green with a yellow belly, green wings, a silver neck and chest, and in the male, a limited magenta forehead patch. Similar to Makatea Fruit-Dove, but with much more washed-out coloring and pink instead of dark legs. The two species are unlikely to be found on the same islands. Call is a rising and falling series of typical dove-like coos.

分布与栖息地
The atoll fruit dove is widespread throughout the islands of the Tuamotu Archipelago, French Polynesia. In a 1999 survey it was found to be uncommon on five out of eight islands visited, but others have found it to be abundant on some atolls which have remained free from the ravages of introduced predators.

行为
The atoll fruit dove is the world's only dove in the tropical Pacific that has adapted exclusively to low coral atolls. It lives in forests and abandoned coconut plantations. It mainly feeds on insects and seeds, usually on the ground. This species also eats the leaves of the "tafano" or "kahaia" (Guettarda speciosa ) trees with odorous flowers.

Turquoise-fronted Amazon
Amazona aestiva
Large, frequently encountered parrot of woodlands, savannas, and open areas. The body is bright green with a blue forehead and a yellow crown. The amount of yellow on the head varies between individuals and regions; some having mostly yellow faces. The amount of red or yellow on the shoulders also varies. In flight shows large red patches on the inner wings.
Black-crowned Tityra
Tityra inquisitor
Handsome, mostly silvery gray bird of tropical lowland forest and adjacent semi-open areas with taller trees. Usually found at mid-upper levels of fruiting trees, sometimes in small groups that mix readily with the commoner Masked Tityra. Black-crowned is told from slightly larger Masked by its solidly black bill. Male is more silvery overall, with a black cap; female had brown face and smaller black cap. Tityras nest in tree cavities, that they sometimes steal from woodpeckers.
Violet-green Swallow
Tachycineta thalassina
A relatively small swallow of western North America. Adult males have a white face and show turquoise-green upperparts and a purple rump in good light. Females and immatures are duller on the upperparts, sometimes just dusky-gray. In flight, note the prominent white "saddlebags" extending up from the underparts to the sides of the rump. Fairly common in a variety of open habitats, often foraging over meadows or ponds. Can be seen in large flocks, sometimes mixed with other species of swallow. Breeds as far north as Alaska; winters primarily in Mexico and northern Central America.
