Fancy Pigeon (and English Carrier, top right) Breeds
Easily domesticated, with short generation times and friendly disposition, pigeons have long been ideal for “fancy” breeders - people who wanted to breed an animal based on looks, like the majority of modern dog and cat breeds.
Where the standard carrier pigeon is the simply-colored greyhound of the sky, fancy pigeons are everything from the problem-ridden, overly-droopy modern iteration of the basset hound, to the functional-but-fancy Cardigan Welsh corgi, to the ornamental-but-sound Maltese.
A fancy pigeon show is more like a cat show than a dog show, though. The breeds have largely been derived for their looks, though a few (such as the Maine Coon cat, or the Scandaroon pigeon) served additional purposes at some point in time. The animals are kept in cages, divided by color and type, and are most prized if they’re relaxed with handling, but still the type to “strut” and show off.
