Eurasian Eagle-Owl, On Schedule, Then Not

Saturday evening was interesting. Flaco was in his normal roost tree, an American Elm before fly out. He hopped to a few branches in the tree before flying out and then went due west quickly. We lost track of him. But about a half hour later, he appeared on his “hunting branch”, which he’s been using for the last few weeks the overlooks a lawn which is locked at night.

He caught two rodents. The area has a mix of Brown Rats and White-footed Mice (or if you’re a purist about how to make scientific names plural, White-footed Mouses), so it’s hard to tell if he has a mouse or a juvenile rat.

After 10 pm, without any warning and without him being flushed by anyone, he flew aggressively to the north. We explored his know locations up north but came up empty. The park’s Great Horned Owl has been moving around lately, and fall migration has started, so we wondered if he was tracking another bird.
