So my friend decided to visit my deck again this evening: After I took this pic through the glass, I started to go out but (s)he was gone. I don't know if I startled him/her (when I went in & out last night and she did not budge) or if (s)he just took off for other reasons. My identification skills sure need work. This is a barred owl. One website says "The best way to find them is by listening for their distinct calls that sound like they’re saying “who cooks for you?” If you hear it, try imitating it back. If you wait quietly and patiently, they may even fly over to scope you out." This is spot-on regarding their being curious. And it says they are likely to be a year-round resident. That makes me happy.
