| Guillemot
Uria aalge
This
is the most common auk to be found on Cornish shores.
Guillemots are expert swimmers and divers.
They
have a long straight beak. Unlike the bird shown here
they are typically dark black. There is a southern variety
found in Cornwall, this is chocolate brown
in summer changing to to grey in winter. Additionally
there is a bridled variety, which has a white ring around
the eye with a line running back from the eyes.
Guillemots
nest on cliff ridges. They produce elongated pear shaped
eggs, which will on only roll in a tight circle. Thus
limiting the risk of the eggs rolling off the
narrow cliff ridges.
