OUR GOOD HARBOR BEACH PIPING PLOVERS COPING WITH WINDSTORMS AND COLD TEMPERATURES

All three PiPls, Mom, Dad, and the Bachelor, are finding drifts of sand, clumps of dry beach grass, and this morning, even a clam shell, to hunker down behind to get out of the way of the harsh winds. They are also doing a great deal of standing and hopping around on one leg.

I hope the wind dies down and soon so we can all enjoy more seasonably spring-like weather!

And what Piping Plover scene would be complete without a bachelor (an unmated male). I hope we get a “new girl” this summer!

Why do birds stand on one leg? “The short answer is that for the simple reason that you put your hands in your pockets when cold, birds stand on one leg to conserve heat. Birds also stand on one leg to relax muscle fatigue in the retracted leg.

The long answer is that birds’ legs have a blood flow referred to as “rete mirabile” that minimizes heat loss. The arteries that transport warm blood into the legs are next to the veins that return colder blood to the bird’s heart. The arteries act as a heat exchanger and warm the veins. Because the veins also cool the arteries, the bird’s feet are closer to environmental temperature and thus don’t lose as much heat as they would if they were at body temperature. By standing on one leg, a bird reduces the amount of heat lost through unfeathered limbs.

Birds that have short legs, such as Mourning Doves, do not need to stand on one leg because they have fleshy feet and they can snuggle down so that their warm belly presses against their feet.” Reposted from “Why is Little Chick Missing a Leg.”

If you see Gloucester’s dog officers, Teagan and Jamie, please thank them and let them know what a great job they are doing. Off and on throughout the day, they are walking the beach, talking to the dog owners who continue to bring their dogs to the beach, and handing out tickets.
