About the Helmeted Hornbill
The helmeted hornbill (Rhinoplax vigil) is a very large bird in the hornbill family. It is found on the Malay Peninsula, Sumatra, Borneo, Thailand and Myanmar. The casque (helmetlike structure on the head) accounts for some 11% of its 3 kg weight. Unlike any other hornbill, the casque is almost solid, and is used in head-to-head combat among males. It is a belief among the Punan Bah that a large helmeted hornbill guards the river between life and death.
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. The body length is 110–120 cm (43–47 in), not counting the tail feathers, which boost the length a further 50 cm (20 in). One male weighed 3.1 kg (6.8 lb) in weight while two females averaged about 2.7 kg (6.0 lb). Although sometimes considered the largest Asian hornbill, their body weight appears to be similar to that of the great hornbill (and considerably less than the African ground hornbills).
