Eurasian oystercatcher, common tern and breeding common redshank. These include waders such as redshank, oystercatcher, common sandpiper and curlew. Recorded breeding seabird and wader species include little penguin, Pacific gull, and sooty oystercatcher. Birdlife in Lochinver includes the curlew, oystercatcher and hooded crow. John Gould described the sooty oystercatcher in 1845. The extinct Canarian oystercatcher from the Canary Islands may have represented a fourth subspecies, "meadewoldi". The American oystercatcher feeds almost exclusively on shellfish and other marine invertebrates. The variable oystercatcher is slightly exceptional in being either all-black or pied. A female oystercatcher lays 2-4 eggs per nest. The oystercatcher is a migratory species over most of its range. This oystercatcher is the national bird of the Faroe Islands. The Canary Islands oystercatcher became extinct during the 20th century. Unsurprisingly for an oystercatcher, it mostly feeds molluscs and worms. The oystercatcher is one of the largest waders in the region. A single species of oystercatcher has been recorded in Georgia.
