Watch the Great Blue Herons return to their "rookery" in mid-March when they repair their nest. The herons are visible until early May when the new leaves on the trees block the view. The rest of the summer and into the fall they can be seen feeding in the shallow waters throughout the Dunes Region.

The Heron Rookery was so named because the Great Blue Herons had developed a "rookery" with over 100 nests.
