I've jogged through a beautiful development in Vero Beach, Florida for years but NEVER heard this bird "call," so I took a video using my phone. The bird is in the virtual center of the screen in a tree which in and of itself is unusal to me as it's clearly a large bird and one I would expect to see on the ground or wading through the myriad of large man-made lakes in Grand Harbor. Though I'm an amateur, I know most of the birds here whether it's winter or summer, but I have never heard this bird. It was obviously very loud as I could hear it from roughly 1/2 to 1/4 of a mile away which made me think of Sandhill Cranes, but as you can probably see it has a curved beak which is more like that of an Ibis, but this appeared to be much larger than any Ibis I've ever seen. I sincerely appreciate the help in confirming this bird. It doesn't relate to this, but Grand Harbor is quite a beautiful development. This is the place that first turned me onto ornithology, and it was the first and only place I've also seen, albeit briefly, two Egyptian Geese. Sincere thanks for any and all help!
