Roviana Rail

A small yellow-olive warbler-like bird with a prominent white eyering. Occurs in forests, shrublands, parks, gardens, farmlands, and urban areas, where it actively forages for fruit, insects, and nectar from the understory to the top of the forest canopy. Song and calls are high-pitched twitters. Can be easily confused with other species of white-eye throughout its wide range, especially Indian White-eye; note contrast of lemon-yellow throat and more olive-suffused upperparts.

A small bird with a long blue tail that is held cocked. Breeding males are usually brilliant sapphire blue with bright white wing patches. Females and nonbreeding males are very plain pale gray, and the patch between the eye and bill (lores) is also pale (compared to Purple-backed Fairywren which has very dark reddish lores). This species is typically found in very open and arid country with sparse bushes, where it often perches on the very top of bushes. Its call is a very fast trill.

Distinctive gull endemic to Galápagos. Adult is easy to identify by sooty-gray body, black head, white crescents above and below eye, and pale rump. Juvenile is grayish brown with tan scaling on the back and wings, and a pale rump. Found along the coast, almost never venturing inland or very far out to sea. Forages along beaches and rocky shorelines, and often perches on boats and docks. It has the smallest population of any gull in the world, estimated at less than 1000 birds.
