Interspecific differences in male vocalizations of three sympatric fur seals ( Arctocephalus spp.)
Abstract This study investigated species recognition based on bark calls and full threat calls (FTCs) in three fur seal species, Antarctic Arctocephalus gazella , subantarctic A. tropicalis and New Zealand A. forsteri , that breed sympatrically and hybridize at subantarctic Macquarie Island.
