Abstract

Magnetic Alignment Enhances Homing Efficiency of Hunting Dogs Kateřina Benediktová, Jana Adámková, Jan Svoboda, Michael Scott Painter, Luděk Bartoš, Petra Nováková, Lucie Vynikalová, Vlastimil Hart, John Phillips, Hynek Burda. Magnetic Alignment Enhances Homing Efficiency of Hunting Dogs. Elife. 2020 Jun 16;9:e55080. doi: 10.7554/eLife.55080. Abstract Despite anecdotal reports of the astonishing homing abilities in dogs, their homing strategies are not fully understood. We equipped 27 hunting dogs with GPS collars and action cams, let them freely roam in forested areas, and analyzed components of homing in over 600 trials. When returning to the owner (homewards), dogs either followed their outbound track ('tracking') or used a novel route ('scouting'). The inbound track during scouting started mostly with a short (about 20 m) run along the north-south geomagnetic axis, irrespective of the actual direction homewards. Performing such a 'compass run' significantly increased homing efficiency. We propose that this run is instrumental for bringing the mental map into register with the magnetic compass and to establish the heading of the animal. Open access paper: ncbi.nlm.nih.gov

Main findings

In over 600 trials with 27 GPS- and camera-equipped hunting dogs, inbound scouting routes often began with a short (~20 m) run aligned along the north–south geomagnetic axis, regardless of the true homeward direction. Performing this 'compass run' was associated with significantly increased homing efficiency.

Outcomes measured

  • Homing efficiency
  • Homing strategy (tracking vs scouting)
  • Initial inbound alignment along north–south geomagnetic axis ('compass run')
