On my way to the lighthouse, along the park road, I had noticed some large birds. When I came back two hours later, they were sitting in the grass in the very same spot, so I stopped.
I had been suspicious that these were wood storks, but I was about 80' from them, and most were sitting in the grass. I did not want to disturb them if that was what they were because they are very rare. So I quickly took a couple of closeup photos and rode away. When I downloaded the photos this evening, it was clear that I had been right. The first photo shows the group, with four birds sitting and one standing. (There is a red X over a smaller crane standing among them.)
And here is a closeup of the bird on the far right so you can see how these ugly birds look in case you ever see any:
I learned about woodstorks about 30 years ago when my kids and I visited the Corkscrew Swamp Sanctuary in Southeastern Florida and saw them nesting very high in bald cypress trees. They have declined in number substantially since then, but have had a little rebound in the last few years.
