The temperature was a lot milder today and the sky remained overcast throughout my morning visit. I was alarmed at the sight of a layer of, what is presumed to be petrol, on the surface of the Lake – it was mostly concentrated around the duck feeding area and the Weir and Causeway. Upon its discovery I reported it and was told it will be investigated – let’s hope the wildlife isn’t badly affected!
A drake Teal was again spotted by the pond on the edge of the wet wood opposite the Waterfall, and 4 Grey Herons were spotted along the River Len.
Presumably because of the petrol spillage, the Lake’s wildfowl numbers were significantly down on yesterday. Only 3 Pochard remained with 8 Tufted Duck, 1 Little Grebe was by the Waterfall, and 1 Mute Swan was by the duck feeding area. Many Mallard, a flock of 6 Tufted Duck, and 2 Cormorant were seen flying over investigating the Lake but moved on elsewhere. It was a brilliant surprise, however, to hear and then see a drake Wigeon – the first of the year – in the bay east of the old boating ramps it flew off west at about 10am.
The gull numbers were up with the flock consisting of at least 86 Black-headed Gulls and 13 Common Gulls.
