My girlfriend and I were lucky enough to see our acrobat squirrel climb the pole and with super strength it managed to launch itself a third of the way up the green anti squirrel baffle, then gravity took over and it was on the ground and running away. It was a great victory against that little critter that had climbed our last bird feeder at will. As for the bird Feeder itself we are pleased. It has become a gathering place for many birds. They pirch and reach in to get the seeds and do but some are very sloppy eaters and seeds end up on the ground. Oh you say that's not good. BUT it is as there are far more birds wanting to eat than there are perches. Keep in mind there are 4 other feeders at our neighbor's just 20ft away. Attatched is a very short vid showing the many birds on perches, birds flying around looking for a free perch and many on the ground cleaning up the dropped seeds.
