This time of year the young Little Blue Herons are around the swamps near the rookeries where they were born. Out on their own hunting I can spot them standing around and watching for something, anything, to happen.
In the above you (barely) see a large dragon fly going by. That’s food when he figures out how to snatch it in the air.
After waiting here this one walked around a little looking in the shallow water.
Ultimately they do figure it all out, but at first it’s a chore.
