Twenty one seabird species
breed in Shetland. These range from the tiny storm petrel, which is smaller
than a starling, to the gannet with its wingspan of almost six feet.
Seabirds come in shades of black, white, brown and grey and the sexes appear
pretty similar. You will notice that colourful features tend to be confined
to the bill and feet. If you get the chance, look closely at a gannet's
feet!
