Rail chiefs have drafted two feathered friends to patrol the skies above their stations to deter nuisance pigeons.<br /><br />Harris hawks Maverick and Zulu have been deployed at stations in Filey, Beverley, and Driffield in East in Yorkshire, as part of a 12-week trial which began in February.<br /><br />The hawks are there to deter the pigeons and prevent them from nesting, but they are not used for hunting.<br /><br />If they prove to be effective, they could be introduced at other Northern stations which have been plagued by pigeons in recent years.
