This is a child’s book circa 1950s about a bird who is trying to bring twigs into his/her birdhouse to build a nest.  The twigs don’t fit in the small birdhouse door because the length of the twigs is too long to fit in the oval entrance.  The bird finally realizes that the twigs can be brought in by turning them to go straight in.  The bird then screams Wowee Kee Flowee!  Of course, I might not have the entire story correct since it has been over 60 years since I read it, but I will always remember Wowee Kee Flowee!
