Treecreeper ssp. ID - Nottinghamshire, UK (1 Viewer)

Can anyone point out the features that would determine whether this Treecreeper is Certhia familiaris britannica or C. f. familiaris?

Thanks.

I went and wrote a long post detailing differences between Treecreeper and Short-toed Treecreeper, before I realised that wasn't the question lol!!!! Doh!!

The 'New Collins' sets out some differences between familiaris and macrodactyla, doesn't mention a 'brittanica'.

At any rate, shows familiaris as having a shorter bill, pure white flank sides, white crown spotting, stronger supercilium than macrodactyla. Don't think yours shows these features.....

From BWP

British and Irish race, britannica. Distinctly darker than nominate familiaris, in both rufous-brown ground-colour and overlay of buffier marks; also rather duller white on supercilium and underparts, with variable but sometimes quite distinct buff wash on flank, rear belly, and under tail-coverts. Differs most strikingly in rear view, lacking 'ghostly' lines on crown and back and having contrasts of wing pattern suppressed.

Crivvens!

I'd just be happy with "Treecreeper" and trip merrily on to the next birdie...

Drat these birds for their feckless breeding shenanigans making new subspecies endlessly.|!|

Summary on page 5, about halfway.
Not the best translation, I know.

Many thanks to everyone who replied. I suspected this was an average British Treecreeper, but wasn't sure.

The information on that Dutch page is awesome - the subject has obviously been well researched... if only it translated to English a bit better!

Cheers
