Appears to be a Sandpiper
I'm not certain, but I'm going to go with pectoral sandpiper. The yellowish legs, the pattern of the wing and back feathers, and what I can see of the beak all seem to match that pretty well.
#2 for the Pectoral Sandpiper
I agree with John a PECTORAL SANDPIPER, Calidris melanotos, mostly brown with yellowish legs, but much larger with more stretched out shape. Sharp contrast separates brown streaked breast from white belly. However striped on back. Males larger than females.

I notice a lot of your birds come from Texas. We got birds out the wazoo here in fall and winter.
But I have one question. Why do I see so many huge flocks of geese flying south or just coming to nearby wetlands every winter, but I almost never see large flocks fling north?
I think this is a Least Sandpiper because the wings are shorter than in Pectoral (viz. don't reach tail tip).
