Abstract

The paper is a practical guide to field methodology for conducting a radio telemetry study of spotted owls (Strix occidentalis) in mountainous terrain. It begins with a synopsis of spotted owl biology and basic telemetry. The criteria used to select which owls will carry transmitters are discussed as are location and capture methods. Instructions for attaching transmitters and recommendations for general, night, and aerial telemetry are presented. Suggestions are given for controlling data quality, for researcher training and safety, and for field interpretation of radio signals. Equipment needs and license and permit requirements are also discussed.
