Both partners of a razorbill pair take turns about in foraging, and caring for the egg or young. Whilst the egg is incubating the non-sitting parent will forage to feed up to 35 miles to to sea, but when the egg hatches they forage much closer - up to 7 miles away.
Razorbills nest in large colonies. They lay a single large egg, the eggs all have different patterns to each other - it is thought that this is to help the parents identify their own egg.
The collective name for razorbills and other auks is a raft, colony, flock of auks.
