We were enjoying a very peaceful, though rather uneventful scene from the Decoy Pool hide when we suddenly found ourselves with a ringside seat for some close-up action. From the corner of my eye I was aware of an unidentified bird suddenly 'falling' into the reed bed close to the hide, followed by a raptor breaking and hovering above the reeds. This flurry of wings morphed into an imm. peregrine,(probably a male from size and build) which then proceeded to hover, circle, drift clear in a feint, return to original spot, hover again and repeat previous behaviour, all at low level over the reeds. This repetitive searching went on for over five minutes until the falcon eventually gave up and moved off to the south. Several minutes after this a healthy looking drake teal emerged from the site - I swear it was whistling nonchalantly!
