Two years ago a pair of Red-tailed hawks built a nest in tall white pine in our backyard and successfully raised one chick. Last year they appeared from time to time but did not nest. This year they enlarged the nest and successfully raised two chicks.  I would like to know if there is any inforation about the number of Red-tail hawks that are currently nesting within the city of Toronto.  If you could point me to that information I would be grateful.
