Those Darn Squirrels Fly South by Adam Rubin
Old Man Fookwire's birds migrate south for the winter, and the squirrels decide to follow. They devise an ingenious plan to fly to a warm and beautiful beach with many new plants to snack on and many new birds to see. Though he would never admit it, Old Man Fookwire misses his furry friends. He joins them down south, paints the local birds, and succumbs to sunburn - so the squirrels have to drive his car back home.
