These look good for Tennessee Warbler. Undertail coverts mostly white, vermivora type bill (although they might not be in that genus anymore? But bill shape is right, very thin and pointed), dull greenish backs, variable bluish-gray color on head, face pattern all right.

Wouldn't have thought of iit myself, but when @akiley mentioned White-throated Sparrow, it really seemed to click into place.

Ruby-crowned Kinglets have a black bill, this bird's bill is paler in color, suggesting Hutton's Vireo. Also it has contrasting pale lores which suggests Hutton's Vireo. However the wing pattern is tough to see because it is in shadow, and the proportions of the bird are tough to tell because of the unusual position sitting on the ground.

Spotted Towhee with the rufous sides, black back with white spots, red eye.

Overall body shape and shape of the head and bill are reminiscent of domestic Mallard to me, but I don't pay much attention to domestic ducks, so I could definitely be wrong.

I'd like to toss out Hutton's Vireo as an option. Note the bluish-gray foot and the robustness of the bill.

The warty red stuff around the base of the bill and the greenish gloss on the black back suggests some domestic Muscovy influence but other features suggest domestic Mallard so I'd say yes.

At least where I am, hybrids are much rarer than Eurasian Wigeons - really good bird!

Too late to edit previous post, but one more thing. The fact that it was eating berries may also be helpful in IDing it. Most wood-warblers are mainly insectivorous, but several of them are known for eating berries or nectar in the nonbreeding season, such as Yellow-rumped, Cape May, BTBlue, etc. This could help narrow it down with a little research. Tanagers eat lots of fruits in nonbreeding season too.

Assuming it is a warbler, wintering in Texas, with yellow undertail coverts, narrows down the options. Yellow, Palm, Orange-crowned, Wilson's, Nashville, or Prairie Warbler or Common Yellowthroat. Larger than Orange-crowned rules out everything except Palm Warbler. This bird doesn't appear to have the undertail pattern of a Palm Warbler, and looks more olive, less brown, on top. Nashville seems like a strong possibility to me, but is slightly smaller than Orange-crowned so that may disqualify it. I suggest Nashville because the bottom tail feather seems to be unpatterned grayish color. It also seems that the vent area is not as yellow as the undertail coverts, but you describe the chest as yellow, this is good for Nashville. However if the bird was significantly larger than an Orange-crowned Warbler, we may want to look at other options beyond warblers. The tail does not seem long enough for orioles, but perhaps tanagers could be considered. Female Westerns can be dull grayish/olive but with yellow underparts coverts. Nashville undertail: (but Nashville is small)

For the shorebirds, the 2 back right birds and the 1 back left bird are Dunlins - note medium size, fairly long drooping bill, brownish gray color. The frontmost bird is I believe a Western Sandpiper - note small size, black legs, rather long slightly drooping bill. The other two birds are dowitchers. Note that they are medium-large shorebirds with long, straight bills, fairly long legs, chunky bodies, pale eyebrows. I believe these birds are Short-billed Dowitcher but I'm not confident in that. The back one is still in some juvenile pumage.

Hey @Nursermk unfortunately I can't see the picture for some reason.

They could well be Semipalmated, I was operating under the assumption that Semipalmateds don't winter in the US, but I don't know anything about Florida so I may be wrong. They do appear rather slender and are relatively dark, especially in the breast, which suggest Semipalmated.

You're correct that the back rightmost bird is a Dunlin. However the other two birds are not Sanderlings, they are some sort of peep, possibly Western Sandpiper. I had never noticed that size variation about Dunlins, but that is interesting. I wonder if the differences in size are related to gender, or disjunct breeding populations, or what?

Looks good to me given the lack of black on the females bill which Mallards have, no visible white line on the speculum, black spots at the gape, unmarked buffy faces. But I've never been to Florida in my life and I've only been to Texas once so I don't have much experience with Mottled Duck, so I may well be wrong.
