VARIABLE OYSTERCATCHER (Haematopus unicolor): SPECIES ACCOUNT

Oystercatchers are found in coastal habitats worldwide, including North America, Europe, Africa, east Asia, Australia, and New Zealand. They also inhabit lakeshore areas in New Zealand, temperate (mild) Europe and Asia, and northern Africa.

Oystercatchers occupy diverse types of shoreline habitat. These include beaches of rock, sand, pebble, and shell. Some species can be found in marshes or coastal lagoons. A small number of species live on agricultural land or pastures.

It is sometimes claimed that oystercatchers help deplete oyster beds used by humans, but there is no evidence to back up these claims.
