I’m thinking it’s a bionic squirrel with a flaky chip causing multiple software crashes and auto-reboots. Or the food offered is coffee beans and he’s going into short duration caffeine high.
However, at about 22 seconds, just before he sits up tall, and freezes. I hear some kind of critter, perhaps recognized as a predator. Small critters that are prey, honored dinner guest, can sit absolutely still for a l-o-n-g time, not even blinking.
David, these are not coffee beans, these are pine nuts. Cedar grows in Siberia.
The squirrel is alive.

There are more squirrels than I’ve ever seen before at or vacation house. All summer I’ve 2 to four of them most days. Fat, shiny, and healthy. I missed seeing it three weeks ago, as I was still at home, but my wife was here and for two days she said the oak tree across the road had 8 to 10 squirrels in the tree for two days. From sunup till sunset. Raining down nut shells onto the road. That have left the pavement stained a darker color.
However, several weeks ago I also saw one of our newest migrant invaders only 50 yards south from the house. A porcupine. At least I think that’s what I saw.
I thought at first it was a big, fat, weird colored groundhog. That might have been dead. I watched it for 15 minutes. It never moved or even blinked. When I pickup truck drove by it fell over on its side, and moved a little bit. I thought the next day I would see it laying dead by the road side. But after I moved farther way, it slowly got up onto its feet and wandered off into the brush.
Critters are often entertaining reacting to simple things.
Many of us were also first attracted to the simple set up of tenkara.
Only four things needed: Rod, line, fly, and a stream with fish in it.
Others find joy with only one thing.
Well, actually a large pile of those one things.
The tail tells the tale.
