Common Tern Field ID Keys

Shape & Size

A stocky fairly small marine tern with longish bill and neck and short legs. Tale does not go beyond wing tips.

Colour Pattern

The Common Tern has a white body with the upperparts of wings and abdomen being light grey. The bird has a black cap and orange legs and bill; very often there is a black tip to the bill.

Behavior

Although it is not an exclusively coastal species, on Madeira this bird tends to stay away from human settlements and concentrates on small islets and coastal areas.

Habitat

This species is broadly distributed around Europe and the world. In Madeira it is a migratory bird that comes to nest in the summer in small numbers throughout all the islands of the archipelago. The Common Tern usually reaches Madeira in.

Distinction from similar species

It may be confused with Roseate Tern thought the latter lacks dusky band under wingtips when in flight or dark shoulders when sitting.
