Birder: an observer or identifier of wild birds in their natual surroundings.
The UPS guy just delievered a package. I saw him coming and opened the door. He was smiling as he handed me the package. He tilted his head toward my car. He was looking at the license plate (BURDR). “Bird Doctor,” he said., his grin growing, like he’d just won the lottery. “Right,” I said not wanting to spoil his day. He whistled as he skipped and hopped his way back to the big brown truck.
