Grim weather for a walk around the hills. Steps Hill still produced plenty of singing warblers. Ivinghoe Beacon still holds the Grasshopper Warbler and there were 7 Wheatear in the usual field South-East of the Trig. I decided best to vacate the hills at this point !!
Wilstone Reservoir produced tons of hirundine and Swift, and the female MARSH HARRIER showed well above the reedbed until at least 9 am (Mike Wallen)
Much earlier, a single DUNLIN flew through and 9 ARCTIC TERNS (Dave Bilcock)
