Birds out on the water include Smew, Goosander, Goldeneye, also Pochard, Shoveler, Tufted duck with some Scaup among them. Still being seen are Black-necked Grebes and the Great White Egrets are still around too. Migratory birds are beginning to appear and Cetti's Warbler has been heard at the Western End of the reservoir over recent days. This is either an early returner or stayed overwinter. The winter work on the reserve including hedge cutting and tree planting has concluded and we are looking at doing some grass cutting of areas left overwinter as shelter for small mammals and insects. We are setting moth traps each month this year on the reserve to see what species we get here. Recently when they were set we didn't get any moths, but we did get a pair of Great Diving Beetles. These predatory beetles feed on smaller invertebrates, tadpoles and even small fish. They are blackish-green in colour with a yellow border to the thorax and around the wing cases. Male Great Diving Beetles have suction pads on their front feet in order to grip the females when mating. Females have a series of deep grooves running along the wing cases.
