Hello dear Piping Plover Friends and Partners,
As are you, I am looking forward to the return of our Gloucester Plovers. With the relatively mild winter we are experiencing, and the fact they have been arriving earlier and earlier each spring, we could be seeing our tiny shorebird friends in little over a month.
About this time of year I imagine well wishers and monitors are becoming anxious, wondering if our PiPls survived all the challenges winter brings to migrating birds.
Last August at the Coastal Waterbird Conservation Cooperators meeting, I met Professor Paton. He is involved with a program that bands and nanotags birds at Southern New England beaches, mostly Rhode Island beaches. He provided some terrific maps based on the data collected from the banding program.
After departing Massachusetts and Rhode Island, the majority of the program’s tagged PiPls are soon found foraging on the shores of Cape Hatteras National Seashore, Cape Lookout National Seashore, and Cumberland Island National Seashore, GA. Data suggests that the Outer Banks are a priority stopover site for Piping Plovers well into the late summer. After leaving our shores, southern New England Piping Plovers spend on average 45 days at NC barrier beaches before then heading to the Bahamas and Turks and Caicos.
As you can see in the map above, it’s easy to understand why the majority of Southern New England PiPls stage in North Carolina.
Why wouldn’t we want to tag out GHB family? Not often publicized is the down side of tagging. Some species of birds adapt well to tagging and some, like Piping Plovers, develop life threatening problems like leg movement disorder. But most troubling of all is that small sticks and other debris can become lodged between the skin and the tag, which causes the area to become infected, which has lead to loss of leg. Tiny shorebirds like Piping Plovers use their legs to propel them all over the beach, to both forage and escape danger. Left crippled by the loss of a leg, the birds will barely survive another year. At one point several years back there was even a moratorium placed on banding plovers.
Perhaps if we had dozens of pairs of Piping Plovers nesting all over around Cape Ann it would be worth the risk of banding a bird or two. But with only one nesting pair, coupled with the typical survival rate of Piping Plovers at less than five years, why not let our one pair nest in peace? Plovers at popular city beaches need all the help they can get from their human stewards. I for one am happy to simply imagine where our GHB PiPls spend the winter.
If you have ever been to a New Jersey beach, you might be sickened as was I to see birds with no less than eight tags, four on each leg. It doesn’t make sense to me in this day and age why one band wouldn’t suffice. Each time the bird was spotted the one set of data provided by one tag could be recorded in a national database.
According to coastal ecologist with The Trustees of Reservations, Jeff Denoncour, this past year (2019), 49 pairs of plovers raised 96 chicks at Crane Beach. They do not band birds at Crane Beach, nor are birds banded at other beaches where the PiPl has been successfully increasing in population, including Winthrop Shore Reservations and Revere Beach.
The species existence is precarious. In 2000 at Crane Beach just 12 fledglings survived 49 pairs and that was because of a major storm. Considering all that a Piping Plover pair has to face at the city’s most popular beach, we don’t need to decrease their chances of survival.
It’s wonderful and reassuring to see updated reports of banded birds we have observed at Good Harbor Beach however, because of data collected in the past, we can fairly accurately imagine where our little family resides during the winter. Banding a single pair will only serve to satisfy our own curiosity, and will do nothing to increase the bird’s chance of survival.
Seven too many bands on this bird!!! Bands are placed both above and below the tibiotarsal joint on plovers (terns are given bands below the tibiotarsal joint only). There are eight possible band locations on a bird’s leg according to banding schemes: The Upper Left Upper, Upper Left Lower (left leg, above the tibiotarsal joint), Lower Left Upper, Lower Left Lower (left leg, below the tibiotarsal joint), Upper Right Upper, Upper Right Lower (right leg, above the tibiotarsal joint), Lower Right Upper, and Lower Right Lower (right leg below the tibiotarsal joint).
