Heliport - Failed to locate any rare gulls over high tide amongst a few hundred Black-headed Gulls. Pintail 30+, Turnstone 25, and some Oystercatcher present.
Cosmeston - A good candidate for a near adult Yellow-legged Gull briefly (with LM) this morning. Typically it flew off just as we taking notes. Plenty of other regular gulls, but none were ringed unfortunately. Tufted duck flock on west lake, but no sign the Lesser Scaup.
