There is a western screech owl in our neighborhood, and I've seen him a few times. Most recently, he visited my yard in a most insistent manner - despite my curiosity and enthusiasm for photos (which didn't turn out particularly well, as you can see), he was determined to stay nearby, flitting between the fence on the property line, to the pole that holds a feeder or two, to a tree near the kitchen window that holds another feeder. But owls don't eat birdseed, so why wouldn't he leave? Mind you, I was thrilled for the guest, but confused about his unusual behavior.

Obviously, both the bird and the mouse couldn't win the standoff. I had to give props to the bird, but I gave the mouse the tiniest bit of a fighting chance, and we released it in the yard, enough of a distance from the owl that it could run. It didn't run far, but it chose the exact wrong direction, and the owl got an easy meal that night.
What a wonderful experience, and one few birders get without provocation. I was in no way baiting the owl and deliberately attempting to draw it in with incapacitated prey (the mouse was genuinely caught, though I'd far prefer not to have mice nearby at all), but with the opportunity, I had to enjoy it. I'm sure the mouse didn't, but you win some and lose some.
