1. Crows are one of the wonderful sentinels that are always alerting us to what is happening in the neighborhood. Listening to them often tells us where the predators are working.
4. I live outside Orangeville, Ontario, Canada. We have both Crows and Ravens in this area, despite the range map not quite including us. There were a pair of Ravens in the 20-acre woodlot behind my house this summer and numerous crows loved to roost in this area during the fall. Is the territory of Ravens changing? Any idea of the key factors influencing the change?
