Within-call repetition may be an anti-masking strategy in underwater calls of harp seals ( Pagophilus groenlandicus )
Underwater vocalizations of harp seals (Pagophilus groenlandicus) were recorded in the Gulf of St. Lawrence, Canada, during the breeding season in March of 1999 and 2000. At high calling rates (>95 calls/min) the background noise levels increase and individual calls may be masked. The purpose...
