The Great Blue Herons (Ardea herodias), length of 46 inches, wingspan of 72 inches and weight of 5.3 pounds (2,400 g), are mating and building their nests at Vancouver's Stanley Park. The trees near the tennis courts is the usual spot which is no different this year. Here is a series of photos taken a week ago yesterday. One heron went to a nearby tree to find a branch for the nest and upon his return passes that branch to his partner who places the find in the proper spot. The first photo shows the bird returning. It's like a relay, isn't it? Enjoy the images.
