Aldabra Drongo
Dicrurus aldabranus
Bold, black fork-tailed bird with a red eye. There is sometimes but not always a tuft of long feathers above the bill. Juveniles have an unusual pale-gray plumage, but still show the forked tail. Found in all habitats with bushes and trees on the remote Seychelles island of Aldabra, including forest, mangroves, and thick scrub. Perches prominently in the open, swooping out to catch insects on the wing. Often follows Madagascar Coucals and Aldabra Giant Tortoises, feeding on insects that they disturb. Song is a repeated sequence of whistles, creaks, and rasps.

行为
The Aldabra drongo feeds primarily on insects and small geckos and lizards. When hunting insects, it will perch on a branch and catch the insects in mid-air. It may feed on the ground, however this behaviour is usually seen by juveniles who are unskilled in mid-air hunting.<p>It is known for being a highly vocal bird, with a wide variety of calls. These calls appear to server a variety of communication needs, including a musical duet sung between male and female during mating, and an alarm call described as "ti-ti-you caw caw".

其他鸟类
Brown Cacholote
Pseudoseisura lophotes
Large ovenbird with rusty-brown plumage, a long crest, and piercing yellow eyes. Found in deciduous forest, second growth, and open woodland. Often also encountered in wooded urban areas like gardens and parks, where it mostly forages on the ground. The song is usually given as an unmusical duet.
Rufous-tailed Hummingbird
Amazilia tzacatl
Handsome, medium-size hummingbird of humid tropical lowlands. Favors forest edge, second growth, gardens in some areas. Feeds low to high and often comes to feeders. Can be difficult to distinguish from Buff-bellied Hummingbird, which favors drier habitats. Rufous-tailed has a dingier, grayish belly and more extensive rusty on the tail, which lacks the distinct fork often shown by Buff-bellied’s tail. Also compare Cinnamon Hummingbird.
Hangnest Tody-Tyrant
Hemitriccus nidipendulus
Tiny, two-toned yellow-and-green flycatcher that inhabit dense woodlands, forest edges, and coastal forests. Note the pale eyes, plain olive-green back, and no wingbars. Whitish below with a lightly streaked throat. Like several other closely-related species it builds an elongated purse-shaped hanging nest. The song is a series of high-pitched “prre-prrew-prrew” notes.
