They both look like Vireos for me but as to which I do not know.
Regarding #1 I think I am with Andy on Red-eye. I see a black edge where crown and supercilium meets that should be absent in YuVi but present in REVi.

I also wondered about that black-looking edege, but to my eye you can see a similar effect on images of Yucatan Vireo. Greyness of upperparts and colour of undertail better for Yucatan I think.
I don’t see #1 being a Red-eyed. They always show a distinctly darker eyeliner and grayer cap that contrast sharply with the olive nape and back. That concolor head pattern is good for Yucatán and some races of Black-whiskered (but lacks whiskers)
Andy
I only plumped for Red-eyed due to having no books here so it as not a well supported punt.
And look at all the trouble you've caused Andy
