Members in the family Haematopodidae are known as oystercatchers. The two species known to occur in Peru belong to a single genus. Oystercatchers show little variation in shape or appearance. They are large, noisy, plover-like birds, with a long and thick orange or red bill used for smashing or prying open molluscs. They show sexual dimorphism with females being longer-billed and heavier than males. The diet of oystercatchers consists of uponlimpets, mussels,
gastropods, and chitons. Other prey items include echinoderms, fish, and crabs. Nearly all species of oystercatcher are monogamous and territorial during the breeding season. There is strong mate and site fidelity. The nest of oystercatchers is a depression in the ground, which may be lined, and placed in a spot with good visibility. The eggs of oystercatchers are spotted and cryptic. Photo: Blackish Oystercatcher. ©Christian Nuñez.
