One of the regular visitors to the dock year round is the Green Heron. It is one of those birds that you don't really notice, but is always around. It is a accurate fisherman that will sit patiently on dock lines that hang near the water and wait for a school of fish to swim under the line and will reach out quickly and accurately to grab its dinner.
Their colors blend into their environment very well, so you don't notice them and the fish don't seem to either. Their neck can stretch over a foot so they can spear their prey and enjoy a good dinner on a very regular basis.
