One last chunky update before it's back to dribs and drabs for a couple of weeks.
Spent today at WWT Slimbridge - while construction and avian influenza restrictions mean the collection side is looking very meagre right now, the wildlife is still top-notch. Being such a well-monitored site means you can easily tip yourself off to what is about in advance - such as a Glossy Ibis feeding each day alongside the entrance road, or that one of the goldfinch flocks harbours redpolls, so they should all be checked.
This all means that I've been able to roll on to 110 to start February.

The escaped Ross' Goose we saw earlier in the winter was also still present in the goose flocks, as were three presumed-escaped Snow Geese, so lots of weirdo interest..!
One other bit of business concerns the alluded-to Forest of Dean photo ID from yesterday.
While at RSPB Nagshead and trundling along quietly through the woods looking for boar, we disturbed a small mammal that ran off into a hole about 2m away and up the slope of the hill from us. 99% of the time you see a small mammal in daylight like this in UK woodland it's a Bank Vole, but as that would be a new species for the year we stood silently and staked it out. When it reappeared at the hole, it became immediately obvious this was No Vole, but an
Apodemus mouse. Up here in Derbyshire, we only have
A. sylvaticus, so ID is no problem, but in Gloucestershire there are two species -
A. sylvaticus and
A. flavicollis. The only 100% reliable field mark, if you can see it, is that the latter has a full yellow-brown 'collar' under the neck, joining the upper-body colour on each side near the front legs (illustrated nicely here:
Mammal Society on Twitter). By contrast,
sylvaticus has a fully white underside of the neck, or just a small yellow spot in the centre of a mostly-white neck. Fortunately, as I noted above, our particular mouse had moved a little up the hill when it retreated from us. This allowed me enough leeway to crouch to the ground and take photos from a couple of angles showing the neck and fur between the front legs that I hoped would confirm if the collar was present or not. The light wasn't great, but it was the only hope of a confident ID, as I would eternally doubt myself if I tried to do it in the field by eye. Either species is rare to see in daylight, but
flavicollis would be a wild lifer. Checking the image on the camera back in the field was no hope. Checking the camera back in the Premier Inn last night was not much better, as it was too hard on the small screen to distinguish shadow from darker fur, but it
looked yellow-brown. Now I have them on the laptop - and, well, they're not good photos, but there is definitely uninterrupted yellow-brown fur running between the legs. My excellent mammal month ends with the first lifer of the year!
