When I drove out to the Lamar Valley each day this past May I would usually check out the road to the Slough Creek campground. It’s a good drive for finding bison, pronghorns and coyotes in the spring. It’s also a prime area for wolves and grizzlies. I would often see this male yellow-headed blackbird as I drove past a small marshy area along the road.
Yellow-heads are a little smaller than their red-winged cousins and not as common. I don’t think I’ve ever seen one before in Yellowstone. I know I’ve never photographed one there before.
