Found behind shudders, guano size was too large to be a Myotis

Process of elimination identification on this bat. Its large ears, blunt nose, overall brownish coloration, lack of "free tail" and its quite large size seem to point to Big Brown Bat.
The big brown bat (Eptesicus fuscus) is native to North America, Central America, the Caribbean, and extreme northern South America.
