Some birding

Managed some birding today although only a trip to Maridalen and in quite heavy rain showers. There are some thin muddy edges on the lake but no waders except for a couple of Common Sandpipers. Also very little else to see: 5 adult Black-throated Divers in flight over the lake and a single adult Red-throated Diver feeding were interesting to and probably a sign of a poor breeding season due to changing water levels. 2 Ospreys were probably an adult and youngster with the youngster calling and a flock of 9 Teal were most likely migrating birds although could be locally bred as there were a couple of males hanging around through May.
In the crop fields around the lake were small numbers of Whinchat, Tree Pipit, Chaffinch and Reed Bunting and best of all a juvenile Red-backed Shrike which was my first sighting here for the year although others have seen a pair so they have probably bred somewhere in the valley.
