Avicultural Data

Status in Aviculture & Aviculture Notes: The following information was provided by John Corder:

There are none in captivity in the U.S. and, as far as I know, almost none outside Vietnam and Malaysia. There are two sub-species. The one from Vietnam (R. o. ocellata) was the species which Jean Delacour managed to breed for a few years in the twenties. Saigon Zoo has recently managed to breed this species, and this photo was taken there. These birds were bred in Saigon Zoo for the first time in1996 by Dr. Phan Viet Lam.

The second sub-species (R. o. nigrescens) comes from Malaysia and had never been seen in captivity until The Wildlife Department started a breeding project about five or six years ago. 3 males and one female were captured, and two of these birds still remain in their breeding complex at Sungkai. They are quite different to the great argus, which is much more commonly seen in captivity, and is also frequently heard in Malaysia and other lowland rainforest countries.
