Fulmar (Fulmaris glacialis)
A member of the albatross family, it displays many of the family characteristics. It's main claim to fame, however, is its inclination to eject a foul, fishy smelling oily substance at anyone who annoys it. This 'foul mere' is where it gets its name.
Often seen in the company of gulls, it stands out from amongst them because of the long, thin, gliding wings. It is quite common, although not numerous, along the Dorset coast and regularly breeds here.
