In reply to Climbing Pieman:
My re-entry to "serious" birdwatching (i.e. actually going birdwatching rather than seeing things when otherwise out and about) was BC (in a previous incarnation) posting about some Whimbrels in a field near Wigan in May 2021 - it's all his fault 😁
Got the White Wagtail but they can be tricky because Pied is the UK sub-species and you can get hybrids to make things even trickier. Males are easiest to identify when in summer plumage; winter, females and juveniles less so.
I would have guessed Little Gull because it looks small and not quite right for any of the other commoner small gulls, but it would have been a guess rather than a positive identification. Not breeding plumage, maybe not adult.
Nervous about the wren knowing BC's previous photos, wondering if it's one of the several sub-species (like St Kilda) rather than the common variety.
