METHODOLOGICAL INFORMATION
Global Positioning System (GPS) data: Commercial GPS sensors were deployed on three outdoor cattle. Locations were set to record every 15 minutes when the animals were active and the update rate was reduced when the animals were not active e.g., during the night, to save battery. 

Activity index: Measured by a dynamometer embedded in the cow-equipped sensors, where each movement along the heave axis over a half-hour period incremented the count by one.

Temperature: Measured by the cow-equipped sensors every half an hour.
