I spent the last week on the island Helgoland which is locatet in the Northsea.
There we had the chance to take photos of Gray Seals (Halichoerus grypus). Between December and February the young ones are born and it's pretty easy to get good photos because they are laying on the beach all the time.
The main Island is Helgoland but there is a smaller island next to it called "Dune" (ger.: Düne). You can go there by ship. It's very nice to whatch them growing.
Here is a picture of a pub on the beach.
