Human Disturbances to Waterfowl
Annotated Bibliography
From 1966 through 1968, a study was conducted to investigate relationships between diving ducks and their food resources on the Keokuk Pool (Pool 19) of the Mississippi River. This information is useful as a baseline from which to measure the impacts of channelization on food resources of diving ducks. Nearly 20 million diving duck days were recorded during each year by aerial and ground census. Night dispersal and feeding were very important to diving ducks because disturbances caused the concentration of 90% of the waterfowl on 28% of the study area during daytime. (D. Thompson = J. D.
