The Norwegian high arctic archipelago Svalbard is the home of the world's northernmost population of harbor seals. Due to their limited distribution in isolated areas of the archipelago, little is known about their biology. Until now no information has been published on their pupping or whether it differs from that of harbor seals in other regions. This paper shows that the peak pupping period for harbor seals in Svalbard coincides with that in Europe, i.e., the second half of June. The pups are born with an adult-like pelt and not with a white coat.
