Reminds me - in an animal stories kind of way - of a squirrel we saw playing with a orange, toy cone in the grandson's backyard, yesterday. Lots of tumbling, rolling, almost as though trying to kill it - or at least teach is a lesson.
I looked at it later that morning and there were a lot of holes in the tip region, from teeth/claws/both.
This morning I walked about eight feet away from a blue jay on the ground, which proximity seemed like a first for me.
