Well, my computer is being really slow so no pictures for right now. May take some pics of my own pretty birds later
But here's some stuff I think is pretty.
Colors:
I LOVE Andalusian and Indigo
Frill Stencil
LOVE Ice
Piebald/splashed/white flights/baldhead
Undergrizzle/Grizzle
Opal
Reduced
Bronze
Mosaics are very pretty!
Basically anything out of the ordinary.
Muffed birds! I really like the long muffs but little grouse legs are cute too!
Breeds:
Like I said, racing homers can be very attractive when in good health/quality. Show type Racing Homers are also pretty (not the same thing as ASR's).
Ice Pigeons/Swiss Crescents (Ice coloration and muffs!)
Indian Fantails - I don't like the huge, loose-feathered, bulky birds. I like the tighter fitting feathers.
Lebanons
Lahores
English Carriers
Lucernes
Hungarians (not to be confused with Giant Hungarian House Pigeons)
Toy Modenas are adorable
Norwich Croppers/Pigmy Pouters
Baldhead Birmingham Rollers (show type is adorable and flying type is also pretty)
West of England Tumblers
And so much more!
Pearl eyes are very pretty to me. Especially on a pretty bird. White eyes are kinda creepy but cool. Bull eyes look nice on white pigeons especially, and on others where it just "fits".
The only things I think are ugly, are Naked Necks...and almost no beaks are ugly (I mean like show type Oriental Frills - literally, no beak at a glance). Double-crested/nasal crested birds can be ugly depending on the breed.
