The Gloucestershire Raptor Monitoring Group has been studying the diet of goshawk using nest trail cameras for the five years 2017-22. In many nests the non-native grey squirrel constitutes a high proportion of prey delivered by the adults. Grey squirrel can cause significant damage to trees, recently estimated to cost ￡37 million a year across England and Wales, and considerable time and money is spent on grey squirrel control. It is expected that a breeding pair of goshawk can provide a form of natural pest control of grey squirrel in the woodland in which they nest, and this article discusses ways in which woodland managers can support them.
