Standard protocols for collecting and recording information should always be used. At the end of each field trip, the researcher should review all radio locations to ensure all data are adequately recorded. This may involve coding data into a computer for later analysis. In general, data can be subdivided into three groups.
1. Information about the tracked animal. Includes morphometric information, sex/age classification.
2. Visit Characteristics. Includes date and weather conditions, such as temperature, cloud cover, wind speed, and precipitation.
3. Observation characteristics. Includes information about animals which are relocated. At a minimum, this should include time, animal's UTM grid location. Also usefull characteristics are: Triangulation or only one bearing, Accuracy (size and shape of the error polygon), Signal characteristics (becomes weaker, becomes stronger, constant or variable).
