The reference is from a photo I look at Fort Mose in 2015. I had heard through the birding grapevine that a pair of great horned owls had been spotted there. When I got to the park I could hear them hooting, but while I looked high and low I could not see them anywhere. What I did see was a man with binoculars and a camera with a giant foot-long lens hunting around also.
He was looking for the owls too! Since everyone spots birds better than I do I asked if I could tag along. Sure enough, he was the one who finally spotted the owls. :)
My lucky day I guess as he said he'd been coming every day for over a month looking for the owls, and this was the first day he'd seen them. I've been wanting to paint them ever since but only now got around to it.
