Jamesdak, would you post some picts of the owls? I haven't spotted any of them there yet, and if you post a few maybe I'll know what to look for.
Nice job with the 400 f/5.6- that seems like a great lens.
I am going to try to hit Farmington Sunday am at dawn tomorrow. Look for the Silver Fourunner packed with lenses if you are around. They will be gone soon til next year.
