SNAKE ALERT: If you don't like serpents, AND somehow missed the title of this post, be aware. Snake photos to follow.
While shooting the dragons, I noticed that several interesting birds were close at hand, including a singing Yellow-throated Warbler. Wanting photos, I switched camera gear over to the 500mm lens, and put the whole affair on the tripod. As I stalked the warbler, I began to hear a strange call from the small creek that fed the pond. Certain it was an amphibian, but unsure as to what species, I wandered over to find the singer.
I never got the chance to find out. Finally, the frog lunged forward in a mighty burst, and shook free of its tormentor. It was gone in the blink of an eye, leaving behind a presumably hungry and frustrated snake. NOTE: When we came back to this spot the next day on the formal field trip, this snake (I would suppose) was in the same spot, hiding under streamside vegetation. It occasionally thrust out into the clear waters and grabbed minnows, so fear not, it wasn't going hungry.
