Magpies Have Outwitted Scientists by Helping Each Other Remove Tracking Devices

An anonymous reader shares a report: When we attached tiny, backpack-like tracking devices to five Australian magpies for a pilot study, we didn't expect to discover an entirely new social behaviour rarely seen in birds. Our goal was to learn more about the movement and social dynamics of these highly intelligent birds, and to test these new, durable and reusable devices. Instead, the birds outsmarted us. As our new research paper explains, the magpies began showing evidence of cooperative "rescue" behaviour to help each other remove the tracker. While we're familiar with magpies being intelligent and social creatures, this was the first instance we knew of that showed this type of seemingly altruistic behaviour: helping another member of the group without getting an immediate, tangible reward. As academic scientists, we're accustomed to experiments going awry in one way or another. Expired substances, failing equipment, contaminated samples, an unplanned power outage -- these can all set back months (or even years) of carefully planned research. For those of us who study animals, and especially behaviour, unpredictability is part of the job description. This is the reason we often require pilot studies.
