Abstract
Reproductive behavior of captive Bali Mynahs (Leucopsar rothschildi) was studied at the Smithsonian Institution's Conservation and Research Center, Front Royal, Virginia. Courtship and copulation are followed by egg-laying, then incubation, hatching, brooding and feeding, fledging, and feeding. Parents become aggressive toward their young at the start of a new reproductive period, marked by a renewal of courtship.
The female does the majority of the incubation, brooding, and feeding of the young, although the male participates as well. The male performs both the bobbing· display and the crest display more than the female does. During these displays, the crest is prominently exhibited and, because the crest is longer in the male, it may indicate the sex of the displayer. A mutual bobbing display occurs throughout the reproductive cycle. During courtship, the synchronous bobbing display often elicits allopreening, a response not seen in unpaired birds . Bobbing may strengthen the pair-bond and function in individual and sexual .recognition in addition to serving as a courtship signal. The bobbing display was also directed toward of her mynahs apparently as a signal of threat.
