Black-crowned Night Heron (Juvenile)

At least 2 different species of herons were gathered in the rapids above Niagara Falls. In the second picture you can clearly see a Great Blue Heron to the left of this juvenile Black-crowned Night Heron and to the right more juvenile Night Heron (I can't tell if they are all Black-crowned as well or if some are Yellow-crowned) the bird the furthest to the right almost looks like a bittern, but I think it's slightly older than the other juveniles.

Immature birds have dull grey-brown plumage on their heads, wings, and backs, with numerous pale spots. Their underparts are paler and streaked with brown. The young birds have orange eyes and duller yellowish-green legs.
