We are so lucky to have a lot of excellent birding spots around Húsavík and Botnsvatn is one of these places. Especially if you are interested in waterfowl. This year there has been an amazing amount of red-breasted merganser and Botnsvatn wasn't an exception. There were at least 4 mothers with a huge amount of youngsters, 2 of them with around 15 chicks. 
We saw a lot of other different birds on our walk around the lake, e.g. a great northern diver, redwings and arctic terns.
