I’m crediting the title of this to the 1985 Song “I Wanna Be a Cowboy” and perhaps showing my age a bit by doing so. Brown-headed cowbirds can often be seen around herds of bison. As the bison graze they chase up insects in the grass which the cowbirds can easily catch and eat. The cowbirds will also eat parasites off the bison. They’re also seen on elk and other ungulates including, as their name suggests, cows. This cowbird was riding around on the back of a bison when I photographed it. Even though I had a long lens with a teleconverter, I did crop this image a respectable amount as it’s not wise to ever be too close to a bison.
