Have you ever gone to look for a American Crow roost in the United States? In winter, crows gather by the thousands for form large roosts and sleep in the winter time. Some will travel as far as 20 miles during the day to forage, but return in late afternoon.
It seems that more and more, American Crows are choosing to roost in urban areas. It could be that they are less likely to be shot at and driven away or there are fewer natural predators to disturb them at night. Now matter how you slice it, seeing a crow roost in an urban area gets the attention of non birders.
We have a large crow roost in downtown Minneapolis it takes forever for them to finally settle into sleep. It’s strange to walk under bare-limbed trees at night while hundreds of crows sleep directly overhead.
There are websites that track crow roosts because there’s still quite a bit we don’t know about them. If you haven’t checked out a crow roost do. Yes, these are common birds, yes they sometimes eat eggs and baby birds (even woodpeckers do that) but it’s unbelievable to see that much bird mass in one spot. It gives those Sandhill Cranes in Nebraska a run for their money.
