This poor guy looked like he was having a bit of a rough day.
One of his antlers was already broken off and then he had a magpie on his back. Kind of a fun shot though and it shows a common interaction between the two species.
Birds will oftentimes “catch a ride” on the back of ungulates like deer and bison. They aren’t being lazy though. In fact, they do this in a search for food, picking ticks and other bugs off the deer.
This benefits both species and is a symbiotic relationship. The birds get a meal while the deer gets itself rid of the insects that could cause discomfort and even infection.
