We had a couple of owls (if I'm not mistaken, Great Horned ones) take up residence in the pine tree next to my office last month.
Being a fan of the species, I wasn't about to pass up the chance to take some pictures.
A fellow owl watcher started making loud hooting noises, which drew the attention (ire?) of the previously-snoozing hooter on the right. I'm just guessing here, but as she's the bigger of the two, I believe the owl on the right is a female.
At 3:15 p.m., this guy was bright-eyed, but not bushy-tailed.
This photo was taken a couple weeks before the previous two, but even without an obnoxious human making stupid noises, she still didn't look very happy.
