I admire herons, herons of all sorts. They have a stately posture, epitomize patience, and have bright eyes that can stare down anyone. My recent trip to Florida had lots of heron highlights. Here I report on the long and short of it, Great Blue Herons and Green Herons.
Standing four feet tall with a wing span of six feet, Great Blue Herons are among our largest birds, even though they weigh in at only 5 or 6 pounds. I was surprised to see them already nesting at Viera Wetlands. In fact, a volunteer said that they were re-nesting, as a recent storm had destroyed several nests that already had eggs. I have seen nesting colonies in NC that were in tall dead trees in swamps, but the ones at Viera were on top of palm trees out in the wetlands.
The herons were sitting quietly on their nests early in the day, but as the sun got higher, the male flew off and began collecting sticks. He would drop down to a broken branch laying on the ground and inspect it, before twisting off a section and flying back to the nest. Occasionally, a male would go to an unoccupied nest and steal a stick to take back to his mate.
Once he lands, he presents the stick to the female, and she accepts it (not sure what happens if she doesn’t like a stick).
She occasionally simply plucked the stick from him without standing up and carefully placed it in the nest. He would then fly off for another. At other times, there was more ceremony involved, with both birds stretching and bill pointing before she accepted the stick. Must have been a really good stick!
The stick ferry finally ended for the morning and I walked down the border of the wetland dike. Soon I found one of the many diminutive Green Herons I saw on the trip. Green Herons are one of our smallest herons, standing only 18 inches tall with neck outstretched, and have a wing span of 26 inches (about one third that of a Great Blue Heron). They are found in freshwater swamps and marshes throughout the eastern half of the U.S. and up the west coast. Green Herons are richly colored in shades of chestnut, dark glossy green, and streaks of beige and white.
They have piercing eyes and are slow motion stalkers of fish and other aquatic organisms at the edge of marshy areas and open beds of wetland vegetation. Green Herons are one of the few birds known to use tools to hunt. They have been observed using twigs, feathers, and other objects to create “fishing lures”. They drop the object on the water surface, luring small fish to within striking distance.
Often, as I prepared to get a shot of one that had momentarily stepped out in the open, it would raise its crest feathers and jump out in pursuit of a nearby Green Heron that had escaped my notice. I’m not sure if these were territorial interactions over food, breeding territory, or both.
This display was usually accompanied by a neck stretch designed to make this tiny marsh hunter appear bigger.
Both species are a joy to watch, and I have decided that time spent with herons, short or tall, is time well spent.
