Razorbill (Alca torda)
These are among the deepest diving birds in the world, they feed on fish and some other marine creatures. They prefer more sheltered sites than guillemots laying their eggs in cavities or crevices. The single egg hatches after 36 days with the young taking their first fluttering steps to the sea after just 18 days.
As with all black and white birds they are very difficult to photograph without under or over exposing one part of the birds plumage. Take readings from the black and the white, set the exposure mode to manual and use a value in the middle of the two readings and slightly under expose from the new value. Neat Image software is a great way of reducing background image noise, but use it carefully as it can also loose detail in the birds plumage.
