Sula bassana [Gannet].
A spring and autumn visitor, and occasionally during summer and winter. When overtaken, as they sometimes are, by strong north winds, I have known them driven to great distances inland, where they are frequently seen lying dead. Immature specimens are now and then procured during their autumnal passage. From their different plumage they are looked upon as distinct from the “solan goose,” as the gannet is here called.
Sterna cantiaca [Sandwich Tern].
An occasional visitor, generally in summer.
Sterna Dougallii [Roseate Tern].
Two specimens have been obtained between Banff and Cullen.
Sterna Hirundo [Common Tern].
Sterna arctica [Arctic Tern].
Annual visitors, generally in autumn. During some seasons they come in immense numbers. Although they do not breed with us, they do so on part of the sandy shores of the adjoining counties of Aberdeen and Moray.
Sterna minuta [Lesser Tern].
