I was talking to the chickadees, and they (and other small birds) were chattering back to me, and while I was quietly putting iNat information into my smartphone, this little guy/girl showed up. Not sure if it was attracted to the bird commotion or not. I'm also not sure if it was more than one, simply because it was moving so fast. I would see it in one place in the bush and then another. This is the only photo I got, and you can make out the brown ears and then the white belly (it's standing, investigating me). Can anyone distinguish, from what's visible, whether this is an ermine or a least weasel?
