When Bob and Lofty move some stacks of tiles in the Yard, they make an exciting discovery. A bird's nest containing a solitary egg is nestling amongst a pile of old tires. Although the nest is not in the safest of places, Wendy explains that they cannot move it because it will frighten the mother bird away. Just as the Machines are starting to wonder where the mother is she returns. It becomes Dizzy's job to "bird watch" whilst Bob and the other machines are at work repairing a roof.
