GOSHAWKS CONTROLLING GREY SQUIRREL NUMBERS
A Goshawk nest monitored by the Forestry Commission and local birdwatchers in Derbyshire showed that 95% of the birds’ diet consisted of Grey Squirrels. Nests in the Midlands and Devon also recorded predation rates of 90% and 68% respectively. Similar trends have been reported in Germany and the Netherlands, where Goshawk is a more common sight. In the Netherlands, it’s seen above open farmland with scattered tree cover, and in Germany it’s gained strongholds in urbanised areas. Remarkably, in Berlin, Goshawk density can be up to 13 pairs per 100sqkm. If a similar increase can be facilitated in Britain, squirrel numbers could soon fall.
