A pair of sparrowhawks are nesting in the rear quad of the Stopford Building. The nest is at the top of the smaller of the silver birch trees. To prevent the pair being disturbed, Andrew Loudon has had the rear quad closed, but you can get a birds’-eye (ha!) view from the Third Floor corridor. Go towards the back of the building and you’ll come to the quad on your right. The female is often seen perching at the top of the fruit tree in the quad.
