Interesting report. American Crows are migrating right now, with lots of birds coming through from Ontario and Quebec. They are daytime migrants. It can be difficult to tell them from local roost movements, because migrants will stop and forage a while in a field with locals before heading out again.
Oddly, perhaps, crows in eastern North America don't fly south, they fly southwest. Some of our Ithaca-raised crows turn up in southwestern Pennsylvania and West Virginia, and other that we have banded in Ithaca in winter turn up in Montreal and Vermont.

Many times I have seen crows commuting - traveling away from a large roost early in the morning or returning to the roost area in the afternoon. Today at 11am I saw a flock of 125 crows flying south high over the east end of Stewart Park. I suspect they were migrating. This was not the time of day I that crows typically commute. Their flight path was the same that I have seen used by migrating Blue Jays earlier in the autumn when they follow the east side of the lake south-southeast but then take a more accurate southerly course once they can do so over without flying over the lake. They were taking some advantage of the north-northwest wind, but when I saw them they were flying at an angle to it. These crows were silent, but I assume they were American Crows because they appeared similar to each other in size and I doubt we could assemble that many Fish Crows here. --Dave Nutter -- Cayugabirds-L List Info: Welcome and Basics<http://www.northeastbirding.com/CayugabirdsWELCOME> Rules and Information<http://www.northeastbirding.com/CayugabirdsRULES> Subscribe, Configuration and Leave<http://www.northeastbirding.com/CayugabirdsSubscribeConfigurationLeave.htm> Archives: The Mail Archive<http://www.mail-archive.com/cayugabirds-l@cornell.edu/maillist.html> Surfbirds<http://www.surfbirds.com/birdingmail/Group/Cayugabirds> BirdingOnThe.Net<http://birdingonthe.net/mailinglists/CAYU.html> Please submit your observations to eBird<http://ebird.org/content/ebird/>! -- -- Cayugabirds-L List Info: http://www.NortheastBirding.com/CayugabirdsWELCOME http://www.NortheastBirding.com/CayugabirdsRULES http://www.NortheastBirding.com/CayugabirdsSubscribeConfigurationLeave.htm ARCHIVES: 1) http://www.mail-archive.com/cayugabirds-l@cornell.edu/maillist.html 2) http://www.surfbirds.com/birdingmail/Group/Cayugabirds 3) http://birdingonthe.net/mailinglists/CAYU.html Please submit your observations to eBird: http://ebird.org/content/ebird/ --
