![]() ![]() The sharply pointed tip of the upper mandible extends well below the lower mandible, making it the largest beak of any psittacine in relation to its body size (only in the Hyacinthine Macaw, Anodorhynchus hyacinthinus, a larger bird, is the beak consistently more massive). The specialized beak is unique among the cockatoos both for its size and its apparent function. It is obviously a very isolated form, however it is viewed, and worthy of extended investigation." (Mathews, 1916). Wrote that "The osteology differs so much from that of other cockatoos that I have separated the present species as of family rank, and it is possible that a closer examination would cause it to be placed nearer the Macaws than the Cockatoos. On comparing the hone structures of Probosciger and other cockatoos species, the great Australian ornithologist, Gregory M. Even Kuhl, who named the genus, was compelled to write "Species intermedia inter Ara et Kakadoes" (species intermediate between macaws and cockatoos). Probosciger to other cockatoo species and the size of its beak led early researchers to compare them with macaws. Conversely, in Calyptorbyncbus, colorful and dominant hands are located on the tail, and there is quite marked plumage dimorphism of the sexes in most of the six species. Apart from the hare red cheek patches which do not occur in any of the black cockatoos, the plumage of Probosciger is almost totally and uniformly black in both sexes. ![]() ![]() Ly be ascertained by comparing the size of the birds, examining the beak, and checking the colors and patterns of the plumage. The superficiality of any resemblance can quick. Studies have revealed, however, that Probosciger has distinctive anatomical peculiarities which clearly separate it from the black cockatoos. Excitement or alarm causes the patch to visibly deepen in color, a process known as "blushing."ĭue to its blackish color Probosciger was formerly loosely classified along with the black cockatoos of the genus Calyptorbyncbus. Another unique feature is the ahility of the hire! toĬhange the color of its naked cheek patches from red to pink and vice versa, depending on its mood. A peculiarity of the beak is that the upper and lower mandibles do not close completely together, leaving the black-tipped, red tongue clearly visible. The main diagnostic features of the genus include the huge, sharply pointed, upper mandible, the bare, red cheek-patches, and the naked inner thighs. ix + 259.T his monotypic genus contains the largest and probably the most spectacular of the cockatoos.
