Northern Mockingbird

Mimus polyglottos (Linnaeus, 1758) 10670
Family: Passeriformes > Mimidae

A long-tailed, grey, thrush-sized bird that is renowned for its song (birds in this family can use both halves of their syrinx independently).

Northern Mockingbird is an extremely rare visitor to Britain, with just a handful of records. The first of these was at Saltash, Cornwall in August 1982. Earlier records had been rejected as likely being of captive origin or ship-assisted. More recently an individual was found in Devon in January 2021. Remarkably, this individual was relocated in Surrey in April and in Northumberland in May.
