Just what exactly is going on in North Bucks as regards GREATER SCAUP. Numbers at Caldecotte South lake have been fluctuating daily of late, from the 8 that Steve Rodwell found several weeks back to just two females a week ago and back to 7. Two additional drakes have arrived in that time indicating that at least 10 individuals have been involved in the influx, perhaps reflecting movement between Brogborough Lake and the site, where 5 additional Greater Scaups were recorded to the original 8.
