Sterna hirundo, commonly known as the Common Tern, is a medium-sized seabird with a white underside, grey back, and black cap. It has a long, forked tail and a pointed, black bill. It breeds in coastal areas, often near large bodies of water, and migrates to warmer climates in the winter. The average lifespan of a Common Tern is around 10 years, and the current population is estimated to be around 1.5 million.
Name Origin: The scientific name of the organism, Sterna hirundo, is derived from the Latin words for swallow, hirundo. The genus name, Sterna, is derived from the Greek word for swallow, stearnē. This is likely due to the swallow's characteristic forked tail and its migratory habits.
