Grumpy Bird by Jeremy Tankard

From chapters.ca:
Bird wakes up feeling grumpy. Too grumpy to eat or play -- too grumpy even to fly. "Looks like I''m walking today," says Bird. He walks past Sheep, who offers to keep him company. He walks past Rabbit, who also could use a walk. Raccoon, Beaver, and Fox join in, too. Before he knows it, a little exercise and companionship help Bird shake his bad mood.
