A topic by JasonJones "Dealing with sounds that keep you awake?" prompted me to ask what strange or unusual sounds have you heard from your hammock?
A few weeks ago I heard a strange owl call. Researched it on the internet and found that it was a Long Eared Owl, which I didn't know we had around here.
I live only a couple of hundred yards from the Atlantic Ocean, and on a still night can hear the Common Loon from a long way off. Kinda eerie.
