Being careful

The scientists do not want to harm the seals. They are careful to minimise how much they frighten them. It is important for seals to rest and to feel secure in their colony. Mother seals are called cows, and suckle the pups (give them milk). In the colony they will stop feeding their pup if disturbed by the scientists. The scientists finish their work as quickly as possible, and then leave Seal Rocks.

The scientists do not visit the colony during the pupping and breeding season (November and early December). At this time there are too many small pups that could get hurt by scared adults seals if they stampede. Also, the territorial bulls could hurt the scientists.
