On the last Wheelyboat session of the season, we had a lovely (if grey!) trip with Doucecroft School down the river to Pin Mill. This rapidly turned into a birdspotting trip as we spotted a flock of birds which had descended on a few of the moored boats. While it was a lovely sight, I was glad they weren’t on my boat – not sure what is the best cleaning product for cleaning guano off decks! After some research we reckon that they are turnstones but do let us know if you can identify them more precisely.
