Crow Help

Sounds like a biblical sign to me. Get a "the end is near" sign and start parading up and down your street.

Mike and Joe, you are both spot on. My parents have a small group 8-10 that have been nesting near their house on the cape (summers) for 4 years.

I'll try to snap a pic, I think you'd be floored by the sheer numbers in this murder. Although they really don't start to gather until dusk/nightfall.

Crows (and ravens as well) are quite intelligent. They know what to look for when scavaging, and have easily associated people with food supplies (trash). They also know what signs to look for, like increases squirrel activity, which also means more food.
Since they are a communal bird species, they are drawn together for companionship and safety, and since they roost at night, are easily spotted moving to and from their roosting sites.
Since they aren't likely to stick together through most of the day, if they are hanging around your area in large numbers, there is probably a food source that is keeping them there.

They do seem particularly unruly this year.

I had to run out side and run directly at a large number of crows "murder"ing a red tail hawk they had assaulted and pinned to the ground.

They seemed to be intending to kill the hawk, feathers were everywhere.

Oak trees around the yard seem to be keeping the crows in the neighborhood. Traditionally, due to the squirrels, it's raptor country, but not right now.
