Pigeon

Domestic breed, escapee.

Probably a juvenile Egyptian Goose.

I can't either but I'll take a WAG. Is it a pigeon?

That is definitely a Lahore.

2 and 3 ...flight feathers from a domestic (feral) pigeon? Common food for a raptor.

That appears to be one of the Trumpeter breeds of domestic pigeons. The marking is referred to as a tail mark. There are several breeds, however, that look similar.

Quite interesting. I know of no mutations in Eurasians or Ringnecks that would produce such a condition. If natural, I'd say melanistic. Quite possible that dove sat down in some sludge, chemical or waste and the feathers are fouled. Note the belly is also dark. However, the rest of the bird is also darkened, to a degree.

And it's a female...by the brown nostrils. Males have blue. I'd say less than a year old by the smudgy forehead. Also a sky blue pied.

Lady Gould or Gouldian finch. Several mutations pictured.

Brown Thrasher?

Looks like a Royal Palm turkey...a domestic variety.

Appears to be one of the flying breeds. Not distinctive enough to tell which. The red on the breast, I would bet, is from red grit, which has iodine In it. Pigeon fanciers feed either red grit or gray grit since the birds have no way of getting it in confinement, and it is essential for digestion, grinding up seeds in the crops of birds.

Oh, and the white coloration is probably recessive white, a simple genetic mutation in pigeons.

Yes, rock pigeon, common color in homing pigeons, which is what this probably is. Yes, used for releases at weddings, funerals, sporting events, etc.

Ahhhhhh, Doc Hollander, an old, sometimes mentor. He was the expert in pigeon genetics.
