This winter, I have been hearing and seeing Common Ravens along the Etobicoke Creek. The first time looking across the Etobicoke Creek in the sky at the Toronto Golf Club and the other time at Marie Curtis Park. I see North American Crows at the Etobicoke Creek. Other than size, there is not much else to tell them apart. The other thing that makes both of these species different is the call. The call I was hearing was the exact same call of the Common Raven. I have never heard or seen Common Ravens around the Etobicoke Creek before.
