Harbor seals are one of the two seal species that breed in Iceland, and July is the season where they usually have their pups! The pups are born with adult fur and the ability to swim, unlike the pups of the other Iceland breeding seal species, grey seals. Grey seals pup later, in the fall. Their pups have white fur and are unable to swim. Here, you can find a guide on how to recognize the adults of both species and an introduction on why it is important to monitor seal numbers in Iceland.
Because harbor seals pup in July, it is also the time for the Great Seal Count, where staff and volunteers from the Icelandic Seal Center gather and count all seals in the Vatnsnes peninsula. Read about it here.
