Gannet, Sula bassana
Birds, mostly immatures have turned up following northerly gales. In 1971, there were two which turned up in Spring, but usually birds appear in the autumn. The most recent record was a healthy adult, which arrived early afternoon in mid-summer, during a brief period of strong wind. Although frequently resting on the water, the bird was watched plunge-diving and soaring around high over the water.
