The Grey-backed Tern, Onychoprion lunatus, is a seabird in the tern family. A close relative of the Bridled and Sooty Terns , the Grey-backed Tern is less common than the other members of its genus and is has been studied less. The three species, along with the Aleutian Tern were recently split into a new genus Onychoprion from Sterna . They resemble the Sooty Tern but with a grey back instead of a black one. Their breast and underparts are white, and the have a black eye line from the bill to the back of the head which gives them their other name, the Spectacled Tern.
The Spectacled Tern is classified as Least Concern. Does not qualify for a more at risk category. Widespread and abundant taxa are included in this category.
