I assume the Yucatan is safe?
Haven't done Mexico but will be in Larry's position soon, looking for a place where we can safely take a child.
What are your tips Larry for best 'buggy birding' destinations?
We found Yucatan a great buggy-birding with car hire destination, Andy :t: Trip report here : https://www.birdforum.net/showthread.php?t=338774&highlight=yucatan+san
remember to also clock the Yucatan (White-lored) Gnatcatcher, prob to be split soon.
Yucatan is more than safe to go.
If you are going to some remoter areas, some basic Spanish is good but certainly not necessary.
We have done it selfdriven in Spring 2017 incl. Palenque. and had a great time. A guide is not really needed (well we missed a lot of species during our poor knowledge on calls in Palenque). Also a good place to combine family and birds with a lot of birdlife at the archeological sites.
I do not remember seeing a female-colored bbgr having a wash of blue on tail and wing-tips similar to what we see here. Others might chime in with different input.
Out of interest, what are the best ways of telling Indigo Bunting from Blue Black Grassquit? May be obvious but I'll admit, I'm struggling.
