A late-ish Sandwich Tern at Ferrybridge © Debby Saunders:
The discovery of this Treecreeper at Pennsylvania Castle caused a mini flap because the initial image posted indicated it had noticeably dirty rear flanks - a fact quickly confirmed by those who rolled up to see it. Sadly, thoughts of something more interesting fizzled out once its seemingly rather short bill and long hind-claw were visible...
...and scrutiny of the wing-pattern doesn't seem to show up anything amiss for a Common Treecreeper: amongst other even more subtle features, there's a noticeable step in the pale wing-bar between primaries 6 and 7, primary 4 has a decent-sized spot at the distal end of the wing-bar and the spacing of the tips of the longest primaries look to be conspicuously uneven. Of course, the call would have been a welcome complete clincher but it wasn't heard to utter a sound © Martin Cade:
What a great day on my local patch here in Wakeham with 7+ Redwing, 2 Chiffchaff, 1 Goldcrest, 2 Firecrest, 2 Brambling, 4 Siskin and a fly-by Snow Bunting. Plus a real surprise with this Treecreeper in Pennsylvania Castle Woods this afternoon. @DorsetBirdClub@BTO_Dorset pic.twitter.com/FeQmeD8bCH
