CLOSED: Three Unknowns - 2 maybe warblers and black bird

These were photographed at Brazos Bend State Park yesterday. The Park is 30 miles SW of Houston, Texas.

This is the black bird - I was thinking female common grackle, but it doesn't really match Sibley's or NatGeo books. So, maybe Brewer's Blackbird?

This is the first maybe warbler ...
Will look some more, but I don't have a clue.

And the second maybe warbler ...

1 Great-tailed Grackle, female

2 American Pipit

3 Myrtle Warbler (formerly Yellow-rumped Warbler)

Oh gosh. I was way off and I really should have known the butter butt. I see them all the time. This just didn't look the same as what I usually see.

Thanks much, Resin! I really appreciate you!
