I live in the Yonge/Eglinton area and for the past 3 days we've had a red tailed hawk flying around screaming constantly. It doesn't seem to be hunting as the massive pigeon flock has been left untouched. Almost seems to be searching for something lost.
It circles up to the north then over west then back down here again.
The cry is so eerie as they are usually pretty quiet. It's almost like a gull cry with that plaintive note at the end - again and again, close together.
If it's lost it's mate, would this explain the behavior?
