Pigeon

Looks small, but fully feathered. Japanese quail?

Yes, and from the red feathers in the wings, I would say an ash red of some pattern with pied. However, an ash red cannot have a blue/black tail, so genetically it has to be a blue, with bronzing in the wings. Only other possibility is a mosaic, which are very rare in feral.

Yes, a grizzle blue check with one of the bronze genes.

That's because, in addition to being rare, they usually don't last long in the wild.

Color and crested variation of a domestic African Ring Neck Dove.

Also, no mention of the black face, which the yellow version retains, or the pink beak. Unless I missed that.

The breed is a Swallow or Wing pigeon,a domestic show bird. Color is blue barless.

Ash red barred domestic. Might be a Racing Homer.

In domestic pigeons and doves, the sex linked gene for dilution often also dilutes the beak and nail colors. This bird looks like a dilute. In addition, the bird has white feathering on the head. This, also is associated with a lightened beak. These are two possibilities with this bird. I'd guess African, as they are prone to a greater range of mutations than the Eurasian.

1st cousin.

Juniper Titmouse? Or is that beak too narrow/long?

Looks like a red winged blackbird. I can see the epaulettes.

It is possible to be both.

Looks to be a fawn or khaki color expression on a domestic mallard. Quite common. This link may help with a lot of the questions that pop up on here in relation to Domestics. https://www.backyardchickens.com/articles/mallard-derived-duck-color-genetics-basics.74277/
