Great White Egret in modern times

On August 8th 1979 I received a phone call, by the old land line of course, about a Great White Egret at Messingham Sand Quarries a FIRST for Lincolnshire no less! Hot foot to the site and get the poorest of images on the old SLR with manual focus and on slide film its blurry and very small -- 40 years on to the day and this one turns up on Waters' Edge just down the road -- it is pretty tame in a busy country park and allows somewhat better images but would not cause any birder movement -- times change quickly in birding -- no local Turtle Dove now for 3 years where there used to be up to 35 pairs in the 70's but Little Egrets daily, Great Whites regular, Marsh Harriers breed and Black-tailed Godwits pepper the foreshore -- there always seem to be more down than ups but maybe that's age related
