Green Heron Bird Species

Green Heron (Butorides virescens)


The Green Heron (Butorides virescens) is a wading bird that can be seen near water across North America and breeds throughout the eastern United Sates, Western Texas and New Mexico. It is 14 inches in length, with short yellow legs and a wingspan of 25 inches. This wading bird has a black head that runs into a blue-gray back and wings. The neck is chestnut in color with a white chin, and a white stripe that can be seen on its neck. Females are a little smaller in size with duller and lighter coloring. The Green Heron is almost invisible as it stands completely still, waiting for a fish to be lured into striking distance.

The Green Heron lurks near the edge of the water and feeds on fish most of the time. It is not unusual, however, for them to include spiders, leeches, reptiles, insects, mollusks and crustaceans in their diet. What makes the Green Heron unique is his tool-using fishing method. The heron will use bait to lure the fish close enough for him to strike. Bait such as twigs, insects, feathers and earthworms are dropped into the water, where the Green Heron waits patiently and motionless for his catch. Due to its diet, the heron will often wander to different locations, but will always choose a freshwater site or water marshes. They usually do not travel vast distances, but on occasion, they have been found in France and England.

During the breeding season the male heron will first find an adequate nesting location before finding a partner. This nesting location will be fiercely protected, as the nesting location and a visual display forms part of the male’s bait to lure a mate. He will only mate with one female in a breeding season. Both the male and female heron will contribute in the building of the nest, with the male finding the material and the female taking care of the construction. She will then lay between three to six eggs, after which both birds will assist in the three weeks incubation period. At two weeks, the chicks are able to snap up insects and fledge the nest at three weeks old.
