Now I personally havent done this, but we were routing a pipeline and it had to be surveyed for owls in the area. So the pipeline company hires these owl hooters to go out at night to call, count and identify owls in the area. Well one night he talked a few of us in to coming out......First he called with an owl hooter, got a response, pulled a white mouse out of a box (snake food, the kind at the pet store), holds out a stick, lets the mouse crawl out the stick, makes some squeaky noises with his mouth on the back of his free hand, and I nearly crapped my pants when that owl flew down out of the trees and picked that mouse off the stick. Way out in the middle of no where too.
Couple things he told me, "Eastern Barred Owls are the devil and should be eraticated from the pacific northwest" and "If you want to here different owl calls or get owl info. go to Owlpages.com." Its free.
