Second supplementary breeding bird census of Big Sand Mound Nature Preserve, Louisa County, Iowa, 1984, was written by Peter C. Petersen. It was submitted to Environmental Services Division, Iowa-Illinois Gas and Electric Company, Davenport, Iowa, July 1984. Three visits were made in 1984 and compared with 1983 to re-evaluate the breeding population of the preserve, with dozens of species listed along with their breeding status. On the title page of the report was a note from Peter C. Petersen to James J. Dinsmore that he had included the most significant records in a separate report. That report listed six species at BSMNP. This item was used as supporting documentation for the Iowa Ornithologists’ Union Quarterly field report of summer 1984.

A report written by Frederic Leopold to address the issue of the continuing decline in waterfowl populations. Leopold voices concerns about the overly optimistic report from Ducks Unlimited regarding waterfowl population and the fact that the effects of over-hunting have been down played. F. Leopold references his brother Aldo Leopold and his book "Game Management" and the philosophy of limiting factors. F. Leopold believes that excessive hunting is the main limiting factor in the declining duck population and not loss of habitat.

A directory of birders in Iowa who were instrumental in the recovery of Eastern Bluebirds in the state in 1990. Includes Bluebird nest box data, information on Bluebird clutches and nests as well as the names and locations of participants with their observations on number of houses, number of eggs, number hatched, and the number fledged. The directory also contains a list of predators and problems that may be encountered on the Bluebird trail with possible solutions, design plans for a Sparrow trap and a Bluebird slot box and a blank 1991 Nest Box Record form to return the next year.
