ABSTRACT: Technological changes have allowed us to further increase the quality and quantity of spatial information gathered for movement ecology and range estimation. We assessed the accuracy and applicability of a PinPoint GPS transmitter for use on small avian species using Northern Bobwhite Quail as our test species. We conducted a series of static tests to evaluate relative impacts of canopy cover across a suite of data collection schedules, and then deployed evaluation units on 6 quail trapped in north-central Texas in 2014. Radial error static test data indicated an overall mean spatial error from known to estimated location was 39.7 m with a standard deviation of 191.7 (range 0-4389.2). The median, or the point at which 50% of the locations are less than and 50% of the locations are greater was 2.68 m with an 85th probability quantile of 6.57 m. Less than 0.08% of locations had radial error >100 m. Units used for field tests on quail collected between 47 and 55 locations (expected 50) and were able to identify both group structure, travel corridors, and loafing habitats for the < 4 days deployed. Our results suggest that use of GPS units on small avian species may provide scientist with increased ability to evaluate questions regarding habitat selection and use, especially in an experimental context.
