|Captive Teals at the Milwaukee County Zoo|
Madagascar Teals nest in tree holes, often belonging to Grey Mangroves. Average clutch size is 6-7, and the eggs hatch after about four weeks. Madagascar Teals are monogamous and are extremely aggressive about guarding their nests. Chicks fledge after six weeks.
Captive breeding programs have been established to save this species, which faces extinction in the wild. The captive populations was founded by birds from the Durrell Wildlife Conservation Trust.
