King's guard

This magnificent bird is Hazel the Harris hawk, who plays an important role at King's College London. The four-year-old raptor - pictured with her handler, Karl Robertson, in the quad at King's College's Strand Campus - is used to deter pigeons and seagulls from building nests on the institution's historic buildings. Birds of prey are frequently used by pest-control experts to keep vermin at bay, including at football stadiums, prisons, RAF bases and even landfill sites.
