Shape-shifting Green Heron

Last season, in the Yellow-crowned Night-Heron rookery along a canal at the north end of the wetlands birding patch next to our south Florida home, a pair of Green Herons selected a secluded spot for their nest. 

Unfortunately, this tree, which extends over the water, had been treated with herbicides by the agency that maintains the canals, and by the time the eggs hatched almost all the leaves fell off to expose the nest. Movie time! 

These brief clips illustrate some interesting behaviors and are best viewed in HD, full screen size. Pardon the shakiness, as they are taken with my hand-held DSLR camera with a telescopic lens, from about 30 feet across  from the nest.


The Green Herons are excellent parents. Here a female feeds her tiny chicks, about 3-5 days old. At the time, we only counted three, as the youngest one was not yet visible (April 15, 2012).

The four chicks have grown quite a bit over the next 3 days. They are now 7-9 days old. Perhaps not unexpectedly in view of the flimsy perches, the smallest chick disappeared the next day, following a heavy thunderstorm (April 19, 2012).

Now on April 22, the chicks are 10-12 days old. This remarkable sequence shows the protective behavior of the male, who had fed the chicks just moments before I started this video. The female then flew in with more food, but the ravenous appetite of the chicks placed them in danger. The male, sensing their predicament, flew in to solve the problem. See how he did it.

The Green Heron can be described as a compact little neck-less ball of feathers...

...or a spindle-shaped pointed object.

But where did that neck come from?

Sometimes it looks like almost any other heron, though its legs are short and its neck is a bit fat.

Then, extending its neck full length, it becomes almost snake-like...

Their color-- How did they ever get the name of "Green?" Sometimes they look as dark as crows.

The immature birds have streaked underparts and can be quite dark in color.

Here is an adult. Why, I do see a bit of green in there!

Usually a loner, it is unusual to see several in a flock. These are immature birds. perhaps some are siblings.

Those wings-- they are surprisingly long and seem to have so many more feathers than expected.

During breeding season, the male does have respectable plumes.

  6. Just brilliant shots and videos Ken. The obvious question is if those young managed to flege? They weren't too far off at the end - big enough to hide in the vegetation if need be?

  7. What a wonderful, educational post. I feel like I have had a private teacher right here in my living room. Your shots are awesome, Ken, and I do not use that word very ofter. I am just beginning my birding quest at 73, so I have a long, long ways to go. Your male heron is so pretty with all of his blue. I bet the gals are happy to mate with him. All of the children up in the tree is such a special capture. I have loved each and every one of your photos. genie

  12. Those videos of the baby herons are so interesting - much better than trying to describe the behavior in words. (AND with my new faster net connection I can finally watch videos successfully!) Great photos also.

  14. Great set of pictures - I think that there is nothing to choose between your reflection shots - although I think yours is a better looking bird!

    Cheers and thanks for linking to WBW - Stewart M - Melbourne
