Scopoli's shearwater

Key identifying features

1. 1

   Yellow bill with a dark subterminal band, on its own a decisive separation from Yelkouan shearwater

2. 2

   Clearly larger than Yelkouan, with long wings held bowed forward

3. 3

   Heavy, languid flight with long spells of gliding without a wingbeat, unlike the hurried flapping of Yelkouan

4. 4

   Upperparts ashy grey-brown rather than black, with a soft, ill-defined transition on the face

5. 5

   Underwing clean white with a narrow dark border, whereas Yelkouan shows a broader, dirtier border
