Ross, I think you are right about his age. I see him as about 4 1/2 YOA.

Yeah, I definitely need to use the weedeater. I hadn't thought about it shortening the flash range. I also have a problem in the settings. During normal daylight, everything gets pretty washed out and whitish looking. I have it pointing North so, it's certainly not getting the full sun into the lens.

Eddie, I agree that an awful lot of them aren't totally nocturnal. Maybe they are just good at patterning me.
