Maybe Blue & White Swallow, Bank Swallow, or even a Martin. Not sure.

Hundreds of swallows fly over every day and all around the apartments, very fast! I’ve never been able to catch one in my camera, though this is one of my best efforts. We also have Keel-billed Toucans fly over occasionally, usually in pairs and very fast! No photos! Same with the Montezuma Oropendola! And parrots and parakeet flocks which are often even higher in sky. None of these birds ever land in the trees around us. 

Church and rest today. No adventures! Back to the bank tomorrow and that will be an adventure!
