cormorants bathe at the earliest opportunity each time they leave the
land, a routine that never varies. The bathing routine for individual
birds varies only slightly and in general is started almost immediately
a bird settles on the water. Initiated as if looking for fish by the
ducking of the head on an extended neck under the water, the head and
neck are jerked downwards in stabbing motion and the feet used to
scratch at the feathers of the breast or the neck to assist with the
removal of dirt or parasites.
