A visit to the Yorkshire Wildlife Trust reserve Fen Bog on the North York Moors yielded excellent views of Whinchats. These beautiful summer visitors nest on the ground. They have suffered a sharp decline in the last two decades, possibly related to changes in their wintering areas in sub equatorial Africa. Fen Bog is a magnificent reserve at the head of the glacial meltwater channel of Newton Dale. In places the glacial peat deposits are 12 metres deep. I hope to return later in the year to see the dragonflies the reserve supports. These include Black- tailed Skimmer, Keeled Skimmer and Golden Ringed Dragonfly. The reserve is also known for its poulation of Small Pearl- bordered Fritillaries and an impressive list of upland mire plant species. If the wildlife is in short supply you can enjoy the steam trains running adjacent to the resrve on the North York Moors railway.
