This is the 5th book in the series called Howard the Owl. In this book Howard teaches the birds all about the changing of their clothes for each season and what they should wear when they travel for the winter. He also tells them about the feather clothing of their young ones; what it will look like when they hatch; who will have feathers and who not; and who will look like their parents and who not. The birds are very curious about this and things do not always make sense to them.
