April 2001 Summary
Foot and Mouth restrictions were lifted midway through the month to give access to the car park and hide, as well as the re-opening of the sailing club and fishing lodge. Spring migrants really began to make themselves known, with several singing warblers, and good numbers of passing hirundines. There were a couple of good counts of Common Sandpipers, while the star bird of the month, was a fly-through Osprey. Overall an extremely productive month.
