How to Identify

I look for the black cap, white body and red eyes. Juvenile birds are brownish, darker where it will turn later to dark grey, and they already have the red eyes.

Where When to Spot

I first saw Black-crowned Night Herons in St. Eustache. Rapids Park Lachine is another place they can be seen frequently, either hidden within a tree close to the water where they like to fish. For photography, St. Eustache is better as they are getting very close.

Black-crowned Night Heron Trivia

Do Black-crowned Night Herons have a short lifespan?

No, Black-crowned Night Herons do not have a particularly short lifespan. In the wild, they typically live for several years, with an average lifespan of around 10-15 years, despite facing numerous predators, including birds of prey. Additionally, terrestrial predators such as raccoons, foxes, and snakes pose a threat to their nests.

Do Black-crowned Night Herons prefer freshwater bodies?
