Varzea Thrush

Medium-sized, dark brown shearwater with silvery flashes on underwings. Narrow wings with quick, deep wingbeats. Widespread and common, especially in the Pacific; can sometimes be seen close to shore. Can be in massive flocks. Extremely similar to Short-tailed Shearwater, but Sooty is heavier and has straighter wings; also look for slightly longer bill and less rounded head. Brown plumage is reminiscent of Flesh-footed Shearwater, but Sooty is narrower-winged and has a smaller, all-dark bill.

Scarce and rather shy antbird of evergreen forest, ​second growth thickets, and overgrown plantations in humid tropical lowlands. Usually in pairs, on or near the ground, where often accompanies army ant swarms to capture prey flushed by the ants. Male is black with white wingbars with bright blue naked skin on crown and around eyes. Female is rusty brown overall with bright blue naked eyering.

Brown and gray thrush with an orange belly, pale throat, and bright orange bill, eyering, legs, and feet. Inhabits forested habitats across Christmas Island, where it can sometimes be found quite close to human habitation; the only resident thrush on the island, and unmistakable. Often encountered foraging actively on the ground. Song is a variable series of doubled notes; calls include an explosive chattering series of rapid chup notes.
