The natural range of the fox squirrel is the eastern half of the United States, excluding New England. Fox squirrels were not originally inhabitants of Ohio. Comparatively little has been written on agonistic behaviour in Red squirrels. Because of changes in ambient temperature related to microclimate variations as the animal moves around, the monitoring of collar temperature additionally provides an index of locomotor activity comparable to that obtained by actigraphy or telemetry.
