Overview
- Researchers tracked 69 ravens with GPS and analyzed movements of 20 collared wolves across Yellowstone during winter-focused monitoring.
- Prolonged following of wolves proved rare, with only one clear instance exceeding 1 kilometer or one hour over the entire study.
- Many ravens repeatedly revisited historical kill hotspots, sometimes flying up to about 155 kilometers in a day along highly directional paths.
- Wolf kills clustered in features such as flat valley bottoms, and nearly half of documented carcasses drew at least one raven within seven days.
- Authors note ravens likely use short-range cues at local scales and call for follow-up work on how juveniles acquire these spatial patterns.
