This fellow was captured a number of year ago but never posted here. It was early enough in the spring that most of the foliage was still brown, but a few pops of green were showing up. This particular pose is fairly common and called a head throw. Despite the dramatic pose, they don't make any sound. It is more of a stretch out the neck and mouth for swallowing a big fish exercise .
