Scarce Chasers at Waddenhoe

Returning from Cheltenham, I stopped off at Waddenhoe as this is my chosen site for the BDS Monitoring scheme. I am monitoring Scarce Chaser numbers over several years to see if there are any population changes. Today, I counted 37 Scarce Chaser between the Mill and the footbridge, which only covers one bank of the river. This implies there were >60 territorial males in total on both banks. Several pairs were in-cop, as shown in my photos above. I also managed to capture a male hovering.
