I now have two red squirrels going after the sunflower seeds in the bird feeder. I had squirrel turf wars go on for over a half hour. They even had a couple of squirrel wrestling bouts. There was also a lot of screeching and chipping/clicky sounds. By the time I was able to get outside without scaring them both off, only the new, younger interloper was there. He kept up his antics, which included flicking his tail very fast.
Go Away, I Said!
I know You are Somewhere
Nope, Not on the Ground
There?
This was taken without flash. No creepy squirrel eyeballs. This guy didn't know if he should run or go back and pig out some more.
Maybe I Should Get More Seeds
This is what happens when you use fill flash to try and get a better photo: evil, glowing rodent eyeballs.
Vampire Squirrel!
