Those Darn Squirrels! By Adam Rubin, illustrated by Daniel Salmieri

From chapters.ca:
The story of what happens when a grumpy old man and some mischievous squirrels match wits - with hilarious results. Old Man Fookwire is a grump who only likes to paint pictures of birds that visit his backyard. The problem is, they fly south every winter, leaving him sad and lonely. So he decides to get them to stay by putting up beautiful birdfeeders filled with seeds and berries. Unfortunately, the squirrels like the treats, too, and make a daring raid on the feeders. The conflict escalates until the birds depart (as usual), and the squirrels come up with a plan that charms the old grump.
