Heidi has already had at least three pups at Helgoland. She prefers a spot at the South Beach, right between the big rocks of the moles, where her pup is always safe and sheltered.
She is also visiting Helgoland in spring for moult.
Heidi has got a pretty recognizable fur pattern. There is a particular eye-catching spot-formation on her left neck side, wich looks like a question mark. Even from a distance, this mark is easily spotted.
