5th April

Although there was still little indication of spring migration resuming at any real pace, census counts of 1 Sparrowhawk, 1 Dunnock, 5 Wheatears, 4 Chiffchaffs, 2 Goldcrests and 4 Rooks were a noticeable improvement on recent days.

The four wintering Whooper Swans are still present, and have become increasingly orange-headed during their stay. The discolouration is caused by the chemical composition of the water they feed in, which may include staining iron and tannins.
