Magpie Mutualism

March 20, 2012

FeederWatcher Patricia Jones-Mestas was lucky enough to catch this moment of mutualistic behavior recently in Parker, Colorado.  Black-billed Magpies are known to pick ticks off of the backs of deer, moose, and other large mammals.  This behavior is mutually beneficial for both species — the Magpie gets a meal, and the deer gets rid of ticks.  Unfortunately there’s no option for “deer” as a FeederWatch feeder type!

    My horses used to have magpie riders in the summer months, sometimes several at a time. They seemed pretty nonplussed by their avian riders. The horses did not have ticks, but the birds could have been snagging flies.
