How do we know this isn't a field vole? Are you going on fur colour?

Which Vole?

Hi Gill, you are, I suppose, right to question the ID. To be honest, my ID was largely intuitive - based on the chestnut colouring. The Field Vole Tends to be more dark brown/ochre in colour.

This demonstrates one of the grey areas in IDs here.

KJ's ID is 'It's likely to be this', and on that basis I agreed. Yes, on the colour.

The problem is that if people agree to a tentative ID, it can either mean that they are making it more certain, or that they agree that it is tentative. If the ID had been 100%, I would not have agreed. You can see lots of examples of both on the site.

When I started on iSpot, I sometimes added an ID with an 'I'm sure' status to override a more tentative ID, but the evolved convention seems to be that agreements go to the first ID that provides a correct name, ignoring the confidence level, so I quickly stopped.

This illustrates why, if records from iSpot are to be harvested for formal purposes, the onus is on the end-user to assess the pictures to determine whether a record can be used in a database or report etc.

ID's Grey area

Point well taken Murdo! I am still relatively new to iSpot and, perhaps, a little too enthusiastic. I will, in future, be more canny. Thank you for pointing this out to me.

Vole species

OK - have added revised ID of 'vole species' then. I think that's as close as we can get with certainty.
Murdo raises a very interesting point, which the iSpot team will hopefully take up with some revised guidance on IDs.

Vole

This is an interesting one, I am 75% certain the original identification is correct, the colour is a very rich chestnut, but it is possible that is a trick of the light; also the ears are large and the eyes small making me err towards bank vole.

To clinch it can you tell me what habitat it was in? From the picture I think it was in a small copse or hedgerow (the presence of dead tree leaves and branches), am I right?

Vole spp.

How interesting you should come up with this now, and gratifying that you should lean in my direction (as it were). If you look at the location you will see that it looks to be in a woodland clearing. How about taking a look at the newer observation this evening and letting me know what you think about that?

Vole

I think it being in woodland clinches it, though I must say it is the weight of circumstantial evidence which does so. I'm happy to call this one a bank vole. Field voles rarely stray into woodland, even in winter.
