...the birds were worth making the effort of putting on the winter clothes.  We had hundreds of low-flying swifts, swallows and house martins hawking over lakes and tracks, and occasionally swifts whizzed through the car park at ankle height.  Fantastic, though risky!

A black tern was watched on Ferry Mere during our dusk chorus walk on Friday, and a grasshopper warbler sang near Moore Lake - both of them "new" birds for several participants.  The evening ended with bat detecting - noctule, pipistrelle and Daubenton's made it onto our list.

After drawing a blank yesterday, a black tern was found on Moore Lake this morning, then it relocated to Ferry Mere this afternoon, to the delight of members of the South Lincolnshire RSPB Local Group, who saw the daity bird just before they headed off for home.
