Heard - and saw - a chiffchaff. Celandines in flower, but fewer than normal. Frogspawn sill looking good. Two blokes in a small outboard-motorised/punt combination, hammering "Closed Season" signs in the lake bed and dropping large amounts of fish food into the water. Without the anglers there to feed them, it seems that the carp will starve, or at least, lose significant amounts of weight. These anglers like the chance to catch a 30lb fish from the outdoor aquarium.
