Picazuro Pigeon

A medium-sized, long-billed bird of primary lowland and foothill forest with a white throat and belly, brown wings and tail, a black mask, a dark crown finely streaked white, and black sides broadly streaked white. Sometimes joins mixed-species flocks, where it often investigates under bark with its long bill. Resembles the other rhabdornis species, but usually found at lower elevations, and has a dark crown streaked with white rather than a gray crown. Voice consists of high-pitched chips, sometimes sped up into a chatter.

Rather local on seacoasts and remote islands south of Tierra del Fuego and on the Falklands. Favors rocky beaches and adjacent shoreline, especially with tussock grass clumps nearby (known as Tussacbird on the Falklands). Like other cinclodes, feeds on the ground, poking under seaweed, and can be very tame. No similar species in range: note dark sooty-brown plumage with only a ghosting of typical cinclodes face stripes and wing stripe. Some regional variation—bill has pale creamy patch at base on South American population and is all dark on birds in the Falklands.

Common, rather large dark petrel of the Southern Ocean; regular migrant north into Humboldt Current. Usually looks wholly blackish with a pale, ivory-colored bill—the white chin is often just a few feathers and frequently is difficult to see in the field, although it can be more extensive, especially on Atlantic and Indian Ocean birds. White-chinned is obviously larger than dark-billed Sooty Shearwater and much smaller than giant-petrels, which have huge pale bills. Pale bill tip distinguishes White-chinned from similar Westland and Parkinson’s Petrels, which have dark bill tip.
