Arrived quite early at EIDB to find that the outdoor gym was already in full swing (i thought that this was supposed to be a Nature Reserve). So decided to head across to view the old Pura Foods site, which seems to have the most scope for interesting birds, probably due to the site's lack of public access. A quick scan revealed at last a Northern Wheatear, standing on top of a pile of stones. It was a female, a bit distant but nonetheless a Wheatear. I have spent many hours searching and waiting for one to crop up, particularly at the Pura site, which looks ideal for this doyen of spring migration. They have been slow this year and other London birders have spent many hours waiting for this species to arrive.
Back at the dock, the gym had quietened down. The copse had a singing Willow Warbler (first of the year) and a Chiffchaff. Four Sand Martins were prospecting the dock walls, and a couple of Oystercatchers flew down the river.There was next to nothing moving overhead and the Thames was quiet. Then the next arrival of keep fitters meant it was time to leave.
