Original HBW caption:
The bare, pink face sets the Grey Crow apart from any other corvid. It also has an atypical juvenile phase, with pale, greyish brown plumage and a pink bill, shown here. Adults, though mainly dark in plumage, can have randomly bleached-looking wing and tail feathers. Confined to New Guinea, where it is widespread, the Grey Crow is part of an old endemic group of Melanesian island crows, many of them with very restricted ranges.
Including Bismarck Archipelago and Bougainville
All of the 943 species known to occur are covered, including the extraordinarily high total of 456 endemics, as well as 5 introduced species, 2 species yet to be formally described and a separate appendix with 75 vagrants. Subspecies are listed also to give a comprehensive overview of the remarkable regional avifauna.
