In January 1993 1.1 wild-caught Writhe-billed horn-bill Aceros leucocephalus were loaned to Audubon Park and Zoological Garden, New Orleans, and between 1994 and 1997 the courtship, mating and nesting behaviours of this pair were observed. These observations are presented here, and diet and chick/ juvenile development are also described. To date nine chicks have hatched, eight have successfully fledged, including one hand-reared bird, and at time of writing five offspring were alive. With a European Endangered Species Programme (EEP) proposed for A. leucocephalus, the offspring from the 1993 (1.0), 1995 (0.3) and 1997 (1.1) breeding seasons have been donated to that future programme.
