Site description Located in Phek district in southern Nagaland, Mount Zanibu IBA is known for its lake, rich forest and for the presence of Blyth’s Tragopan Tragopan blythii and Rufous-necked Hornbill Aceros nipalensis. The lake is known as Dzudu and is surrounded by dense forest (Choudhury 2002a). This IBA is hilly, with Mount Zanibu being the highest point at 2,426 m above msl. The area is covered with primary Subtropical Broadleaf forest, with small areas of Temperate Broadleaf forest on the hill tops.
AVIFAUNA: Besides the Rufous-necked Hornbill and Blyth’s Tragopan, Mrs Hume’s Pheasant Syrmaticus humiae has been reported, especially from the border, which is covered with secondary forest, trees and grass (Choudhury 2002b). There is an old record of another globally threatened species, the Purple Wood or Pale-capped Pigeon Columba punicea from near Phek (Ripley 1952), which is not far from this IBA. Except for a brief survey by Choudhury (2002a) there has been no detailed study in the area. The Purple Wood Pigeon has not been re-sighted by any one else recently.
OTHER KEY FAUNA: Hoolock Gibbon Hylobates hoolock, Stump-tailed Macaque Macaca arctoides, Asiatic Black Bear Ursus thibetanus, Dhole or Wild Dog Cuon alpinus, Leopard Panthera pardus, Barking Deer Muntiacus muntjak and Serow Nemorhaedus sumatraensis are the noteworthy mammals (A. U. Choudhury pers. comm. 2003).
