Where and When to Spot
I first observed Black-crowned Night Herons in St. Eustache. Rapids Park Lachine is another location where they are frequently seen, often concealed within trees near the water where they prefer to fish. For photography enthusiasts, St. Eustache offers better opportunities as the herons tend to come quite close.
