Marail Guan

Small, active songbird with long, pale-tipped tail and warm brownish-orange on the forehead, rump, and tail base. Grayish brown above and pale below overall, with a white throat and black-speckled breast. Frequently cocks and fans tail. Endemic to the Mariana Islands (Saipan, Tinian, Agiguan, and Rota) and Yap, in the Carolina Islands. Extinct on Guam. Inhabits a wide range of habitats, from remnant native forests to towns. High-pitched, tinkling song often has a descending quality. Formerly grouped with other closely related species under “Rufous Fantail.”

Fairly large, long-winged storm-petrel with deeply notched tail. Complex and subtle variation across extensive range. Typical flight style is somewhat bat-like: bounding with jolting twists and turns. Plumage looks chocolatey-brown in good light; paler than Wilson's or Band-rumped Storm-Petrel and with more extensive buffy bar on upperwing. Rump color is variable; birds in the Atlantic have a mostly white rump, usually with a thin dark line down the center. Pacific birds are more variable, sometimes completely dark-rumped, especially "Chapman's" Storm-Petrel (southern California to South America). Occurs in the Pacific and Atlantic Oceans, mainly in the Northern Hemisphere. Fairly common but stays far offshore; rarely seen from land. Compare especially with Band-rumped Storm-Petrel; on Leach's, look for more obvious pale upperwing bar, more deeply notched tail, and bounding flight style.

Fairly small, chunky tanager with stout bill. Almost entirely blue, darker indigo on head, paler cerulean towards tail. Bright lemon-yellow throat distinctive; also look for inconspicuous chestnut undertail coverts. Sexes alike. Uncommon around forests and edges in subtropical zone, usually in pairs or small groups. Tends to stay at lower or middle levels of trees and shrubs, often following a mixed-species flock.
