People living in the nation’s capital were treated to a rare sight — a snowy owl perched on statues and monuments far from its breeding grounds in Canada.

A snowy owl is causing a hoot after landing in the District this week. Hobby ornithologists and non-birders alike are celebrating the somewhat-rare bird, which was first spotted around late December near the McMillan Reservoir, according to the Washington Post.

It’s since made several appearances throughout the National Mall and outside Union Station. The bird of prey has been spotted, uh, preying on the local delicacy of pigeons and rats. Lots of them.

In an interview with The Washington Post, Matt Felperin, a naturalist for Nova Parks in Northern Virginia, said the night owl has been using the area as a hunting ground after dark. And according to Felperin, it’s making a killing.

“She’s doing marvelously, and she’s doing us a favor with the rats,” Felperin said.

Meanwhile, some locals have begun to roost around the bird at Union Station. According to one bird enthusiast, they’ve even given her a name: Duchess.
