There was indeed a female GOOSANDER at Olney Mill this evening, with 3 well-grown ducklings in tow (there had initially been 6 young). A splendid sight, and one I never thought I'd see in Bucks. Possibly the same female that bred at Gayhurst Quarry a few years ago? Surprising that the male hasn't been seen at all.
Also 1 Curlew and 12 Barnacle Geese at the mill (Rob Hill)
