When I lived in Williams Lake, BC Canada, I lived where I could see a roosting tree on the horizon, it was an old snag, which still had lots of bare branches.  About 50 birds tended to roost in it nightly, especially in fall. Later I lived above the lake in this same town and observed hundreds of crows (and ravens) returning nightly as they flew past my windows. I couldn't see where they roosted but they flew past for a good while each evening in groups both large and small. I had about 5 who frequented my area, and if I put food out for them they showed up in minutes and got so they cawed at me whenever I was outside.  They ignored my spouse but he never fed them.
