Seagull on the Backyard Rocks

My backyard is Humber Bay Butterfly Sanctuary on the north shore of Lake Ontario. The rocks where this gull is flying is what I see from my back balcony. Raising my gaze to the lake and the Toronto skyline across the bay, i tend to see this sort of view. Don't boat myself, though. To the right is a quiet bit of water between the shore and the island. People play here, biking, walking their dogs, rollerblading etc. . Waterfowl are plentiful like this pair of newly arrived female American Widgeons. The people in the condo adjoining ours have a flag in their back yard, which tells you where on the globe this is.
