It’s about 20º this morning and the roadrunner wants to warm up a bit. It fluffs out its feathers and spreads its wings a little to expose the dark feathers underneath. Turning its back to the sun, it warms itself.
This was shot through the living room window and obviously not the best location, but I don’t control where the bird is. I could improve the shot by keeping my windows cleaner!
This is a photo I took a year ago. It’s the backside of a roadrunner. It’s not easy to figure out what you are seeing, but you can see the dark feathers underneath. Again, the branches in front and behind it don’t help.
