Non veni pacem mittere, sed gladium.
Looks like a titmouse
More like a collie, I'd say.
I had one of those little bastards (tufted titmouse) land on my head and pull out a piece of hair.............
Did you slap it like a mosquito?
They do this to cattle & horses too. They must be gentler than they look, because it doesn't seem to bother the horses.
I don't know about horses, but the collies shed off their rear "skirts" so much, they don't seem to feel it at all when the stray tufts are plucked, like this titmouse is doing.
