Razorbills belong to the auk family, along with guillemots and puffins. They look rather similar to guillemots but their dark feathers are black rather than chocolate brown, they are plumper and have thicker, heavier-looking bills. On the water, a razorbill floats higher than a guillemot and its longer tail tilts upwards.
The razorbill is well-named because the edges of its hooked upper beak are very sharp indeed, enabling it to grasp fish well and to defend itself against predators.
