Found just north of the Queenston/Lewiston bridge along a footpath beside the Niagara River. I extracted one of the "teeth" and it was hollow. Entire object is 35 mm long.
I saw this striped skunk walking the edge of the embankment. Everyone was watching the falls and didn't notice him. I had to use the built-in flash to get the picture.

Robin seen in park on the way to the docks for a ride on the Maid of the Mists below Niagara Falls.
Upstream from the boat dock there was a rock sticking out of the water and the cormorants gathered there when they were just sitting and digesting. In the foreground you can see one of them in the water with just the head and neck above water.
Gulls were abundant below Horseshoe Falls and appeared to be feeding on stunned or ddying fish which had gone over the falls.
