Because of its dark plumage and lack of long plumes, the Little Blue Heron was not a major target for the plume hunters that decimated the populations of most of the white egrets and herons in the late 1800s. During the 20th century, Little Blue Heron has extended its range northward and increased in population in many areas and are plentiful in South Florida.
The Little Blue Heron nests in colonies, sometimes alone and sometimes in large mixed heronries, Little Blues tend to nest along the edges of the group. While it's said to be wary and hard to approach I have found just the opposite as these photos show. All three of these were photographed a couple feet away from me and they didn't appear bothered by my presence at all.
