B&W treecreeper-like bird. Yucatan, Mexico (1 Viewer)

In Central Yucatan 3 weeks ago, saw this black and white fellow activity clambering along branches and even foraging upside-down. I've look through Van Perlo (my only resource) a dozen times and can't seem to figure it out. Reminds me of a treecreeper in Europe. Any ideas?

He is a North American migrant - Black and White Warbler......I was in the area last month and it threw me off too as it creeps - like a creeper.

Ah, yes! Just read up on it and yes, it's a warbler that creeps. Weird! I was thrown off by most of the pics of this warbler, which show the male with strong striping on throat and chest, which my bird does not have. It seems the females/immatures are paler underneath.

Thank you, Fiscalshrike, for setting me on the right track!
