クロズキンコサイチョウ Lophoceros hemprichii

A medium-sized dark-brown hornbill with a long tail. The bill is dull reddish and the belly white; there is white in the outer tail. The flight is floppy and loose. Found in dry savanna habitats, particularly on and around cliffs and other rocky microhabitats. Similar to Crowned Hornbill, but darker, with a duller bill and more white in the tail. The call starts with “keeya” notes, then usually progresses into a rapid piping.
