Two great crested grebes fight on a reservoir over the affections of an onlooking female.  The lone male provoked the courting pair by continually calling and approaching them, before the paired male attacked the intruder.<br /> <br /> The aggressive battle lasted around 20 seconds before the solo male retreated to the other side of the water - uninjured but with damaged pride.  The photos were captured by amateur photographer Mike Barth at the Sutton Reservoir near Macclesfield, in the northwestern county of Cheshire.
