Size of a European blackbird, about 25cm. To 14 years. Also other insects, and small reptiles and amphibians. Unlike other species of Magpie Robins the male and female Seychelles Magpie Robin have similar plumage. They forage on the ground, often following large animals, including giant tortoises and pigs, which disturb invertebrates in the litter.
Nests are simple cups of dry grass and coconut fibre.
Only a single egg is laid in a breeding season. The species also possibly occurred on Curieuse and Felicit . Continuous human settlement in the Seychelles began in 1770, and natural vegetation has been much degraded. Some open feeding areas in plantation have become overgrown. The low population size is a risk.
