The Gough moorhen is a monogamous species, forming breeding pairs that defend a territory together. Breeding occurs from September to March, peaking between October and December on Gough (2). Both sexes construct a cup-shaped nest in the grass, made from sticks, into which two to five eggs are laid. The eggs are incubated for approximately 21 days, also by both sexes. Two broods are possible in a year and, if managed, the first brood will help with the rearing of the second (3).
This species feeds on vegetable matter, seeds, invertebrates and carrion, and scavenges petrel carcasses and garbage. Invertebrates are often foraged for in abandoned and active albatross nests, as well as petrel burrows (2). Interestingly, it actively hunts mice and preys on unattended eggs of burrowing petrels (6).
