Bali Myna (Leucopsar rothschildi) have been the subject of a number of captive breeding programs since the 1990s. While these gorgeous birds are incredibly popular in Bali, even appearing on Bali coins, their numbers are currently estimated to be under 100 individuals in the wild. Because breeding programs are so important to the Bali Myna’s survival, careful records have been kept on their captive breeding habits and behaviors. While the myna’s chief breeding years happen before the age of five, with decreased but still active breeding until about age fifteen, mynas can live a good deal longer than that in captivity. It’s likely that because many mynas won’t make it to those older ages, their reproductive energies are focused into their younger years. This knowledge can help conservationists to decide which individuals are viable parents, and which ones to retire from the breeding pool.
