The wood duck in the San Joaquin Valley, California

This brief paper is the first attempt to present a study of the habits and status of the wood duck, Aix, for the San Joaquin Valley of California. In a natural history survey involving a migratory bird such as this, two year' s observations cannot hope to produce a clear and precise picture, nevertheless it is hoped that some of the material presented will be of value to future investigators.
