The use of call playbacks for censusing loggerhead shrikes in southern Alberta

Description

The loggerhead shrike is considered to be a Species of Special Concern. A variety of survey techniques have been used to monitor population size and distribution of shrikes in Alberta. These include Breeding Bird Surveys, surveys conducted from moving vehicles, ground searches of roadside habitats, and intensive block surveys. This report presents the result of experiments with the use of call playbacks to improve detection frequency of loggerhead shrikes during surveys. Loggerhead Shrikes showed variable responses to call playback, but birds were more likely to be detected when playback was used. The playback technique therefore offers a valuable tool for enhancing surveys for shrikes.
