Blacky The Crow in "An Egg That Wouldn't Behave"

Just imagine how Blacky felt when that egg began to slip. Do what he would, he couldn't get a better grip on it. It slipped a wee bit more. Blacky started down towards the ground. But he wasn't quick enough. Striped Chipmunk, watching Blacky from the old stone wall, saw something white drop from Blacky's claws. He saw Blacky dash after it and clutch at it only to miss it. Then the white thing struck a branch of an old apple tree, bounced off and fell to the ground. Blacky followed it.
