Although harbour seals have often bred successfully in captivity, there is little information on the behaviour and welfare of captive mothers and their pups. This study used video of a mother with her newborn pup (P1) during the first 16 days post-partum and further video of the same mother with a second pup (P2) during days 19–22. The most frequent behaviours in the water were body nosing and close body contact. The observations with pup P2 allowed for expanded descriptions of contact and following behaviours in the water. With P1, the mother displayed most responsibility for following and approaching, i.e., for maintaining contact. Suckling usually occurred immediately after the mother led the pup from the water to an onshore suckling location. P1 often rested alone while its mother checked on it continuously from the water and signalled it to return to the water by nudging, nosing and splashing at it. This mother engaged in close contact with both her pups, with both the mother and both pups displaying body language suggestive of positive emotion and, therefore, indicative of good welfare. These observations offer an argument in favour of allowing female harbour seals in captivity to give birth and wean their pups naturally.
Wilson et al. (Mon,) studied this question.
