Cistothorus
As in: if you've seen one troglodyte, you've seen 'em all?
If you're in Eurasia, yes indeed, reflected in the lack of an adjective in the common name given it in the UK, for instance. (It is simply known as "****".)
I'm with #1 regarding genus hint.
I think that this is the only species in the Bird Banding Lab database for which no one has ever recaptured a banded individual...
Yes, a Cistothorus, but which one Sedge or Marsh? The white streaked head seems to indicate the former, but would either be in Texas in April?
I was thinking Troglodytes troglodytes but I think the Wren (or Winter Wren) would be darker underneath? So I'm now leaning toward the Sedge Wren (Cistothorus platentsis) due to the streaks on the crown (which I think the Marsh Wren wouldn't have).
