Half-Tail is digging in the dirt.
It's a little hard to see in this photo, but Half-Tail's tail is cut short. See the gray spot, normally the tail would be about a third or more longer than it is. Hence his name, Half-Tail.
Frinley is keeping an eye out.
Frinley and Half-Tail hit the trees for safety.
This is Frinley - more curious than scared. Frinley's name comes from his being more outgoing than some squirrels. I can't say for sure, but I think I've had encounters - and photo shots - with him before.
Half-Tail is very curious as well, hanging upside down to look while chewing some delicious morcel. His hind legs hold him so well he can use both front paws to hold his food to his mouth. (Those photos were too dark to show.)
Frinley safe on a higher branch.
