Little is known about how seabirds catch their food outside the breeding season but using modern technology, researchers at the University of Liverpool and the Centre for Ecology & Hydrology have gained new insight into their feeding habits.
Seabirds, including puffins, are often elusive and spend much of their lives at sea, feeding exclusively there. The period outside of the summer breeding season is particularly mysterious as the birds spend their time far away from land.
Using depth recorders, researchers compared the feeding behaviour of puffins with two closely related species, guillemots and razorbills, to find out how deep and how long they dive for during the non-breeding period. MORE
