The Magellanic oystercatcher (Haematopus leucopodus) is a species of wader in the family Haematopodidae.

It is found in Argentina, Chile and the Falkland Islands in freshwater lake and sandy shore habitats.

[2] When inland during breeding season, the Magellanic oystercatcher feeds largely on earthworms and insect larvae, probing soft ground and mud with its sharp beak.

At other times of year when at the coast it forages for mussels and limpets and feeds on crabs and polychaete worms.

These include false-brooding, when it moves to sit on an imaginary nest site, and tail-flagging, a ritual aggressive display involving raising tail and wings.
