If you google that question, you’ll find that gray squirrels can jump at least 4 feet straight up in the air, and at least 9 feet horizontally. I’ve had a peanut feeder hanging in the buckeye tree about 7 feet from the trunk of the tree all winter, and just today a gray squirrel finally figured out how to get to the feeder. (Shot through the window looking into the afternoon sun with a terrible reflection.)
The momentum of the landing creates a violent swing in the feeder, which can dislodge the squirrel that might be just hanging on with its toes.
After several failed attempts involving collisions with the plastic dome over the feeder,
the squirrel successfully launched itself from just the right height on the tree trunk, with just the right trajectory arc, to land most of its body on the side of the feeder.
Athletic and smart, that’s the gray squirrel key to success.
