The birds were very confused on this afternoon. Thinking it was sundown, thousands of birds (mostly crows) were gathering as they normally would, but this was just before noon. I have seen them all leave the city to roost for the night. It is quite amazing. As a matter of fact, quite a few years ago, I worked out of the the city and I happened to work right at their roost. I worked in an abandoned Hydro plant, used as a studio for many made for TV movies and series. The plant was surrounded by trees and as the crows came from the city they would fill up the trees (as described below). It was incredible to watch and listen to. I bet you 20,000 crows would gather.
If I may say, I am listening to the soundtrack of The 5th Element as I work on these photos and post them. It is an amazing soundtrack, if you get the chance to download it or buy it.
*Beginning in fall as the days draw in, crows do something strange and interesting: birds that forage over a large area during the day come together to spend the night in a communal roost. Crow populations are high in many areas, and roosts of a million birds have been reported.
They begin to gather about an hour before sunset. Single birds, small flocks and sometimes long lines of hundreds or thousands of birds converge on a particular area.
Where Do Crows Roost?
Crows in North America used to roost in the countryside but, beginning in the ‘60s, and increasingly through the ‘70s and ‘80s, they moved into cities. They choose both evergreen and deciduous trees, often clumps of trees surrounded by open spaces. To find a crow roost, watch for birds at sundown and follow them.
What Does a Crow Roost Look Like?
Before going to roost, crows typically congregate in staging areas nearby. It’s a noisy gathering and the birds mill about, calling continuously and rearranging themselves. As full darkness approaches, they move to the roost where they can occupy a tree so thickly that it appears to be leafed out in shiny black.
Through the night, the roost is fairly quiet, but the clamor begins again as sunrise approaches and the birds leave in groups to begin the day’s foraging.
