Last year all my sightings in the field off Edgeley Road were based around one particular bend in the stream. This year, though there've been plenty of prints showing the voles are using the bend as a thoroughfare, there have been no signs that anyone's claimed it as a territory. Till this week, and a large latrine on the bank plus some feeding. I waited twenty minutes but didn't see anything, so moved down to the lower bend where I saw two voles fighting, and then down to another stretch where I watched what might have been nest-repair or -building. Strange how colonies shift up and down, so that a spot will be favoured one year, and abandoned another.
