Through the seasons Squirrels have tried to overcome the squirrel-proof tray/baffle to reach the bird feeder.
Mostly they failed, but did become competent pole dancers.
"What's up? And how do I get there?"
"I can do this."
There were multiple failed attempts
but she made it (even when wet and slippery)
and tasted the rewards of success.
It wasn't a one-off. There were more attempts, many more failures . . .
Her friend also learnt how to breach the anti-squirrel baffle and to raid the birds' sunflower seeds.
