Birmingham Roller
A variant of Tumbler (Columba livia domestica)

Representative Tumblerphoto — a dedicated image of this exact morph isn't available yet.
The most popular performing tumbler, bred to spin backward in a tight, fast somersault as a kit. A working flying breed judged on roll quality and depth.
Keeper tips for this variant
Fly hungry and on a controlled feed schedule — a roller flown too full won't perform, and excessive depth selection risks fatal rolldowns.
