The breeding season runs from May to October (11). Maximum clutch size is two, but only one chick per nest survives due to siblicide (11). 35% of the known breeding population exhibits cooperative breeding strategies (3). The most common cooperative strategy is known as 'polyandry', when a female mates with more than one male (2).  The Madagascar fish-eagle is a fish specialist (12) and catches its prey by snatching fish from the water's surface rather than by plunge diving (2).
