Red-tailed Hawk??? (Buteo jamaicensis)

We picked up my granddaughters Bronwyn and Saabrah from school yesterday afternoon. We sat out on deck chilling, and enjoying a beer, when this guy perched in a tree about four houses down. Off I went, trundling along the street, trying to get within a decent range, neighbours thinking , whats this guy up to? It was great to see quite close-up, and the way smaller birds were mobbing it, as it at in the tree.
