Seychelles Warbler Acrocephalus sechellensis

A medium-sized yellowish-olive bird with a long tail. A scarce endemic that is restricted to a few granitic islands of the Seychelles, where it is found in scrub, woodland, and mangroves. Vaguely similar to Seychelles White-eye, but larger, longer-tailed, paler below, and without bold white spectacles. The cheerful song is a quick series of several musical warbling notes in an up-and-down pattern. Also gives scratchy call notes.
