Elly and Rommel stopped dead when he (or she) called to us. He allowed me time to run inside and grab my camera. Then additional time to go back inside to get my long lens.
I had zero time to mess with exposures and whatnot and only managed 3 good shots before he flew away.
But man, did this make my night. I've finally seen the source of the "Whooing" I hear every night.
And according to the Internet, he was a Great Horned Owl: a male to be specific.
He finally got tired of me messing up prime dusk hunting time and took off towards the horizon.
I hope to see him again.
