About a dozen Canada Geese seemed to be the only waterfowl about.
3 Lapwing on the fields over Lumbutts Road were the only obvious waders: they were well back from the road so there may have been others.
On the plus side, there was a Wheatear (possibly two) and a norhtbound Swallow flew over the dam. Several Meadow Pipits were singing over the fields to the south, and odd snatches of Skylark could be heard from Langfield Common.
A good number of Pied Wagtails were about, and half a dozen of them suddenly flew up to pursue a low-flying raptor that was heading north and about to cross the Calder Valley. Not my strong suit, identifying raptors disappearing into the distance, but I suspected female Merlin - smallish, brown falcon with no obvious tail band.
2 pairs of Canada Geese.
2 Willow Warblers singing, amongst other woodland stuff, including Coal Tit.
