Had a look off Horseshoe this evening where the main highlight was the number of Common Terns present - 1160 in total with regular groups of birds ranging from 30 - 90 birds gaining height & heading high inland. 250 Sandwich Tern were also present. 3 adult Med Gulls were in the roost & waders for the night were: Green Sandpiper, Greenshank & 6 Whimbrel. My first Merlin of the autumn was on the marsh. Hirundines were moving south with a mixed martin flock of 50 birds & a 30-strong flock of Swallows through. A Corn Bunting was singing next to the airfield.
