A database called WHOOPER contains whooping crane (Grus americana) observations for the Rocky Mountain foster-parent population and currently consists of 1,438 observations covering the period 1975-1987. The dBase III Plus database management system for microcomputers is used for the application. This description of the data base and its capabilities updates the prototype database described in the 1985 Crane Workshop.
