Tri-axial acceleration data from California condors (Gymnogyps californianus), California, USA

We outfitted nine condors in a flight pen with patagial tags, each with a unique ID, and a proprietary solar powered Global Positioning System-Global System for Mobile Communications (GPS-GSM) telemetry device weighing 50 g (Cellular Tracking Technologies, LLC, Rio Grande, NJ). The units collected tri-axial acceleration data at a rate of 20 Hz. Data were transmitted once daily over cellular networks and then downloaded to a server.
