The great cormorant has more sensitive hearing under water than in air. This new knowledge may help protect vulnerable bird species.
Many aquatic animals like frogs and turtles spend a big part of their lives under water and have adapted to this condition in various ways, one being that they have excellent hearing under water.
A new study shows that the same goes for a diving bird, the great cormorant.
This is surprising because the great cormorant spends most of its time out of the water. It is the first time we see such extensive hearing adaptations in an animal that does not spend most of its time under water, says biologist Jakob Christensen-Dalsgaard, University of Southern Denmark. MORE
