All in South Texas
The first two are a plover (I think?) in flight (upper left).
Next two are I think a spotted sandpiper.
Last one was near the spotted one, but it looks a little different to me.
CLOSED: Spotted Sandpiper? and Some Plover?
1-2 Piping Plover
3-4 yep, Spotted Sandpipier
5 Solitary Sandpiper
Thanks much! I guessed right on the Piping Plover, but then just wasn't sure. The white on the uppertail and light back made me think Piping, so I guess I am getting there slowly but surely.
