Jorge J. Ayub scanned the public beach north of Boston on a hot summer weekend, already crowded with what was predicted to be 1 million people drawn to the annual sand sculpture festival. And on the sand were four pairs of tiny shorebirds, brooding over chicks which were still too young to fly–those chicks are a precious addition to the national effort to save a bird once down to 139 pairs in Massachusetts. It was Mr. Ayub’s job to help protect the plovers. “Everyone made it,” Ayub, an ecologist for the Massachusetts Department of Conservation and Recreation, reported at the end of the long weekend watching over the birds.
Plovers are shorebirds that migrate from the southern US and the Caribbean in the spring. They nest on the Atlantic shore from South Carolina to Newfoundland. Once common, they were hunted and then squeezed out of their habitats by coastal development until, in 1986, the federal government listed the Atlantic Coast birds as threatened.
The bird’s recovery has been slow and halting. After three decades, the Atlantic population stands just under the 2,000-pair goal set by federal law. But the star has been Massachusetts, which has seen plovers increase to a high of 687 pairs from 139 pairs in 1986. One reason for that: intensive “chick-sitting,” in which conservationists sometimes spend all day watching over the birds. Plover chicks lead a risky existence. They cannot fly for about four weeks. As they scamper down to the water’s edge to feed on small insects and worms in seaweed washed ashore, they are easily hurt and to children who cannot resist chasing them. “We’ve rescued them from kids,” says Ayub.
The plovers are surrounded in much smaller areas by “symbolic” fencing. “If we put up too much fencing, people will be upset, and they are going to walk right through the nesting areas,” Ayub says. Ayub added the fencing has taken only 14 percent of Revere Beach–even less at low tide–and is removed as soon as the chicks take flight.
