Hatch Up Your Troubles (1949)

Continuity mistake: When Jerry orders the baby woodpecker out of his home, you can see that Jerry's right foot is facing sideways but in the next shot it is now facing straight.

Continuity mistake: When the mother woodpecker leaves the nest for lunch at the beginning of the cartoon, she puts a sign saying "Gone for lunch - back 10 minutes" on the nest, but when Jerry returns the baby woodpecker to his nest later on, the sign has disappeared.

Continuity mistake: When the egg rolls under Jerry while he is sleeping in his bed, you can see that the inside of Jerry's pillow is coloured yellow with green stripes, but in the next shot it is now blue with yellow stripes.

Trivia: When the baby woodpecker walks glumly away after being thrown out of Jerry's house, he goes over to Tom who is sitting in a deckchair. The magazine that Tom is reading has "Saturday Evening Puss" on the front cover, which would be used as the title for a 1950 Tom and Jerry short.
