Little Goose by David Mraz, illustrated by Margot Apple

From chapters.ca:
Round things like pebbles and puddles and marbles and bubbles remind Little Goose of something, but he can't remember what it is. So he sets off on a journey in order to recall the special feeling he gets when he sees baskets and buckets and balls that roll. But Turtle's round rock isn't quite right, and neither are the flies that buzz 'round Frog's head, nor Mouse's round house, deep down in a hole. Only when he returns home does Little Goose remember what makes him feel cozy and comfy, and happy, too - that most special place within the soft circle of his mama's wings.
