Alewife (Alosa pseudoharengus) at Peter Oliver's Colonial Mill Park

It is interesting how the temperature affects the movement of herrings swimming from the sea and up the rivers to get to their breeding grounds. This year we had a warm March, and the herring were very plentiful in moving up. Most of the month of April until very recently the temperature has been frigid, and the herring have disappeared from the Nemansket River until the last couple of days when the herring/alewives have started back moving up the river to Appsowanset Pond where they breed.  Over the next few days, as the weather warms up in the water temperature increases, we should be seeing more herrings swimming up the river.  Peter Oliver Colonial Mill Park in Middleborough Massachusetts is an excellent location to visualize the Herring run.  Also, many gulls wait around to grab the herring and feast on them along with great blue heron and osprey.  If you have a chance, and in the area.  Visit and watch the continuing nature cycle pass before your eyes.
