Feather duster budgerigar Feather duster budgerigar Feather duster budgerigars ("Melopsittacus undulatus"), sometimes called budgerigar mops, are budgerigars that have a condition characterised by overly long feathers that do not stop growing at usual periods, giving the bird the appearance of a feather duster. This condition is sometimes known as chrysanthemum feathering. The contour, tail and flight feathers do not stop growing, and they do not have the necessary barbs and barbules for the feather's structure to interlock. The shaft (calamus) is also curved, and so the feathers appear deformed and fluffed out. Individuals with this condition often appear less alert than nest mates.
A Bird in a Bonnet ends with the word "Oshimai!". "A Bird in a Bonnet" is one of six cartoons scored with stock music by John Seely from the Capitol Records Hi-Q library because of a musician's strike in 1958; the others are "Weasel While You Work", "Hip Hip-Hurry!", "Hook, Line and Stinker", "Gopher Broke", and "Pre-Hysterical Hare". This cartoon is the only Friz Freleng cartoon to have a Seely score; two others were directed by Chuck Jones (both starring Wile E. Coyote and Road Runner), while the remaining three were helmed by Robert McKimson. A Bird in a Bonnet A Bird in a Bonnet
