We have several Barred owl's living around my house. They come in real close if I leave the h/p sodium light on -- they love bugs!
When we first moved here, we were laying in bed & I heard this: http://www.entertonement.com/clips/mvfsydxlbn--Barred-OwlOwls-
Made the hair stand up on the back of my neck!
Never heard or saw one before moving here. They make all kinds of strange noises when there's more than one in the area -- their way of communicating, I guess! The next day, I heard one real close & went out in my driveway under the light, & there was one sitting on a low wire about 10 feet above me! I was able to get the wife out there right as it dove toward us, then upward & landed on the roof of my barn! We could feel the breeze from it's wings -- that's how close it came! Was the coolest thing I'd ever seen.
Massive wing span -- wish I had the camera then!
