Crows heading for the roost at dusk in Pittsburgh (photo by Kate St. John)

13 October 2025

My sixth floor windows are a good place to watch birds in flight. Last month I saw chimney swifts diving into Cathedral Mansions chimney (see chimney swifts video in 2020). This month Pittsburgh’s growing winter crow flock flies past my window on their way to the roost.

They’re Back!!!!

On Saturday 10 October I counted 3,000 crows but was too busy counting to take pictures.

Last night I captured lots of video which I stitched together for a bit a minute+ of crows in flight. Crow fans will watch the whole thing but most of you will want to ditch out early.

Several times in the video: Are you wondering why a single crow wheels, turns, and head back and down? He’s seen his buddies on the roof next door and wants to join them.

For now the crows are roosting somewhere near Pitt but as their numbers grow to 10,000 or 20,000 they’ll wear out their welcome and be urged to “move along” and change the roost. When that happens they won’t fly past my building anymore.

The last few days have been a rare opportunity to count crows outside my window.
