Environmental Impact Research Program: Auditory Survey Methods. Section 6.3.5. U.S. Army Corps of Engineers Wildlife Resources Management Manual

Abstract

This report on auditory survey techniques is designed to present an overview of auditory techniques (also known as call counts) used to survey populations of selected avian species. The surveys are generally used to determine the relative abundance of a species rather than to estimate absolute density. Since auditory surveys provide only an index to the size of a population, they are most useful for monitoring trends through time or for comparing abundance among study sites. Auditory survey procedures are described for the mourning dove (Zenaida macroura), American woodcock (Scolopax minor), northern bobwhite (Colinus virginianus), and ruffed grouse (Bonasca umbellus). Information on sampling procedures (including design variation), data analysis, and application to local studies is provided. Cautions and limitations are described for all techniques.
