[Along] With House Sparrow, this is the favorite species of every Ornithology TA when it comes time to administer the semester's field practicum. And it's a bird that vexes the beginner no end, while it comes easily to birders with even a little experience.
Let's look at habitat. The bird appears to be perched on a large, robust grass, of the sort one might expect in a marshy edge or a wet ditch. Bells ringing yet? Its streaky plumage might suggest an emberizid sparrow, but in reality there are no emberizids this densely and darkly streaked and striped. The strong legs and feet and the spike-like bill point us in the right direction: this is an icterid, a New World blackbird.
From there it's easy. The moderately long tail with scalloped undertail coverts, the rusty tone of the wing with the clear white tips on the median coverts, the heavily streaked underparts, and the hint of pink at the front of the long, clear supercilium make this a Red-winged Blackbird.
What about Tricolored? A bird of that species in the analogous plumage would show a solidly dark belly contrasting with the paler streaked breast. And it wouldn't be in Texas, either, though I confess that that's the easy way out of an identification problem that can at times be more challenging than this classically well-marked red-wing makes it look.

Female red-winged blackbird. The beak is too long for a sparrow. Though it took me a long time when I was first seeing this bird as a 12-year-old to figure that out. "Grandma, why are those sparrows always hanging around with the red-winged blackbirds at your feeder?"
I'm with Sven on this one.
Certainly a blackbird, probably a female - but the white streak on the wing suggests the possibility of being a young male. The feathers have enough gray to make Tricolored Blackbird a possibility.
Female red-winged blackbird, for certain. Icterid bill rather than a sparrow bill, and a hint of yellow in the lores.
This bird always causes consternation for ornithology students during a field practical exam!
I agree - female redwing. Sitting on the canegrass like that is another good clue - they love the wetlands.
