Seal hunting! Part 5 - But the harbor seals have become fewer - and no one really knows why

We accompanied seal researchers from the University of Gothenburg, to Koster. In the archipelago on the Swedish west coast. Koster is one of the places where the harbor seals give birth, at the beginning of summer every year.

The researchers come here to count the returning seals and to see how many pups are born.

At most, a female harbor seal can give birth to one young per year, but in lean years, they can wait to give birth until the following year.

Now the researchers are worried, for three years in a row they have seen that the number of harbor seals decreased, and that’s not a good sign.
