The last two weeks we've started to get our first southern movement of Waders, along with other early spring / summer breeders that have either failed to breed or have already fledged their first brood of chicks. It's a good time of year as you really could get anything turning up at the Reservoir. Lucky for me I get to scan the banks while on Boat patrols at work and the last two days have pulled up quite a few waders that I would have missed if walking on the bank. Today I found a single Oystercatcher, 6 Common Sandpiper and 2 Redshank. Also this week we've had a pair of Little Ring Plover, Greenshank, Green Sandpiper and a single Juvi Lapwing. 
Hard to believe that we used to have Lapwing breeding onsite in decent numbers and now we're lucky if we get a single summer visit from one.
