This blog post covers an awesome first day of my birding trip in Western Mexico earlier this month with Greg Homel of Natural Encounters Birding Tours with 75 species (starting after 2 pm) highlighted by close encounters and photos of Buff Collared Nightjar, Black and White Owls and Mottled Owls at the end of the day.  More posts to come.
