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.

An essay written by Walter Rosene reporting the findings from a study of nesting Great Horned Owls that he and Bob Walker completed over the course of seven years from 1934-1939. Included in the report are the outcomes from the eggs that were laid and brooded each year, the record of the food found in the nest, and the behavior of the owls. In the seven year study of this particular nesting site, six young birds grew to maturity and left the nest, and all of them were banded.
