When in the north east and the day looks easonable take a trip to the Farne Islands to see the breeding Guillemots, Puffins, Shags, Cormorants and Arctic Terns. Wear head protection though, the Terns are aggressive.
The boat trip is not far but it is dependent on the sea state.
There are very large numbers of these species and you can get really close without bothering them. Keep to the walkways and follow the warden’s instructions.
