Diet of the introduced Gough Moorhen Gallinula comeri on Tristan da Cunha

Introduced Gough Moorhens (Gallinula comeri) on Tristan da Cunha exhibit a generalist diet, primarily consisting of vegetation but also including arthropods, earthworms, introduced rodent remains, and anthropogenic debris. This mirrors their dietary behavior on native Gough Island, where they consume a varied range from plants to scavenging and predatory items. The study analyzed stomach contents of four birds, revealing their adaptability and potential ecological impact in the restored Tristan da Cunha ecosystem.
