Night Hawk

Spotted this young (I think) hawk moments ago when I was walking my dog. Dashed back in for my camera and took this picture. Not great, since it's a night shot and I didn't have time to set up a tripod, get all the settings correct, etc., but I did my best. I've never seen a hawk at night, so I was a bit surprised. At first I thought he might just be enjoying the lawn sprinklers, but then towards the end I could see him trying to hold something down..possibly a small rodent he had caught?
