A Green Heron flew to a rock in the midst of floating Azolla probably because the aquatic plant had accumulated at the edges of the pond creating a thick mat which was impenetrable for seeing anything in the water. It found a small clearing where the Azolla had momentarily drifted away, giving it a clear view of what was underneath. While I watched, the Green Heron took a stab into the water, but it was an unsuccessful attempt to grab breakfast. As it resettled it feathers, it prepared to try again, keeping its eye on the prize.
