Receding waters means a whole new place to feed for these birds. They may have long legs but there is a limit to how deep they can handle.
From my perspective it was great too. There are a few places, in the shade, where deeper water prevents us from getting anything but a few gator shots.
Now I can catch these guys ‘shoveling round’ in the water close by.
Note; in the above photographs you can see how they will sift through water and ‘spit it out’ catching small prey.
