Use captive breeding to increase or maintain populations of bustards Bird Conservation

A review (van Heezik et al. 2002) of the same project found that the number of eggs laid by females ranged from approximately two (for five-year-old first-time breeders) to 8.5 (for four-year-old females that had bred before). The number of eggs laid increased with breeding experience and, although no comparisons were made to productivity in wild bustards in this study, other studies suggest that wild females normally lay between one and four eggs.
