Haulout behaviour of harbour seals (Phoca vitulina) during breeding and moult in Vesterålen, Norway
Haulout behaviour of harbour seals (Phoca vitulina) in Vesterålen, Norway, was investigated from1 July to 23 August 2003 using a combination of high- and low-tide counts performed from boat and elevated land positions, and hourly counts from the land positions through 12- or 24-h cycles at specific...
