Young bat my neighbours found (unharmed) in their curtains. Released the same evening. Pipistrelle?
Young water vole (above and below).
Mum - the same adult vole I saw last night, I think, because of band of dark fur above the eyes.
Mum and youngster - no fighting at all!
.I was privileged tonight to watch what I assume must have been a family group: at least two, possibly three young of exactly the same size sharing a piece of apple and swimming up and down the same stretch, plus an adult who seemed to be wholly tolerant of their presence in a way that suggests a parent and offspring. I saw this same adult vole top up the latrine too, so I'm guessing a female. In other words, mum and babies. There was at least one more adult lurking on the fringes.
Delighted to report too that we have a hedgehog in our garden.
