The helmeted hornbill is a very large bird in
the hornbill family. It is found on the Malay Peninsula, Sumatra and Borneo.
It has mostly blackish plumage, except that the belly and legs are white and
the tail is white with a black band near the tip of each feather. The tail is
long and the two central tail feathers are much longer than the others,
giving the bird a total length greater than that of any other hornbill species. Source
