The adult SANDWICH TERN was still present over Marsworth this evening, giving great views, especially when close to the Bucks bank. At 19:30 it crossed over to Startops, where after a few circuits it settled down to roost on one of the anti-algae bales. It was still there when I left at 19:50. If you haven't seen this bird yet and you'd like to, I'd recommend infra-red goggles - it'll be gone before first light in the morning!
A BARN OWL was quartering the field behind the Marsworth reedbed this evening, and I had 26 CORN BUNTINGS come in to roost.
Cheers & Good Birding,
