Great Blue Heron

The largest heron found along the St. Lawrence River and lakes near Montreal. When not resting, the bird either stands still in the water or moves slowly along the shores searching for frogs, snakes or fishes to catch.

How to Identify?

It's the largest heron seen in Montreal. Mostly grey with some white along the head. It can be easily distinguished from the slightly smaller heron, the Great Egret which is completely white.

We combine physical characterics and behavior patterns with location and seasonal aspects to identify species.

Where & When to Spot?

Usually found moving slowly within the reed, or it stands on wood trunks or stones in flowing water. Can be seen from early spring to late autumn as long as the shores of river and lakes are not frozen. Migrates South late autumn.

With each photo, we store date and geo-location providing us data about location and season of observation. We also use a tracking utility to save observations in the field when there was no opportunity to take a good shot.

Anything to add, to correct?
