Grover climbs a tree and finds a bird's nest with some eggs in it. The eggs hatch, and the baby birds think Grover is their mommy. When the real mother bird arrives, she mistakes Grover for one of her babies. She gives them all a flying lesson, but Grover promptly falls to the ground.
Notes[]
The Little Bird puppet is used as the mother bird, with larger feminine eyes added as well as extra plumage. Jerry Nelson performs her, as well as doubling as one of her chicks.
