Sandpipers Exhibit Different Feeding Behavior Depending On Position In Group

University of Montreal The behavior of semipalmated sandpipers (Calidris pusilla) feeding during low tide in the Bay of Fundy, New Brunswick, surprised Guy Beauchamp, an ornithologist and research officer at the University of Montreal's Faculty of Veterinary Medicine. While individuals on the periphery remained alert and used short pecks to feed on the mudflats, birds in the middle of the group relaxed their vigilance and fed on a different resource. The more peripheral group members were...

Research Bolsters Importance of Horseshoe Crab Spawning for Migrating Shorebirds Speculation that the welfare of a small, at-risk shorebird is directly tied to horseshoe crab populations is in part supported by new scientific research, according to a U.S. Geological Survey- led study published in Ecosphere, a journal of the Ecological Society of America. Population health of the red knot, a shorebird species whose population has plummeted over the last 15 years, has been directly tied to the...

A bar-tailed godwit, a bird banded near Victoria, Australia, was found more than 8,000 miles away in the western Arctic area of Alaska, wildlife experts said. While tagged birds are sometimes seen in the region where they were released, it's rare to see them so far from a release site, Wildlife Conservation Society scientists said in a release Friday. While we know that birds from all over the world come to the Arctic to breed, to see a living example first hand is a powerful reminder of the...

Declining numbers of a shorebird called the red knot have been linked to bait use of horseshoe crabs. Long-term surveys of red knots showed that the average weight of red knots when they leave Delaware Bay has declined significantly since their primary food source, eggs of horseshoe crabs, has been reduced. The study also revealed that red knot survivorship is related to departure weight, and that the population size of red knots has declined by more than 75 percent. "We concluded that the...

By DAN SVINGEN The weather is cooling. The kids are studying. The harvest is roaring. The shotguns are shining. These iconic images proclaim that autumn is soon upon us. For some of our fellow creatures, however, that is hardly a news flash. Incredible as it may seem, many arctic-nesting shorebirds began their "fall" migration in early July. For most such species, adult females were the first to depart the top of the world, leaving their mates to shepherd the tiny puffball chicks...

Experts are pointing to restrictions in U.S. east coast states on harvesting horseshoe crabs as the cause of the recent surge in the population of endangered migrating shore birds after years of over-fishing.Horseshoe crabs lay the eggs on the shores of the east coast every spring, and the migratory birds rely on the eggs as a source of food.Before the restrictions were put in place, commercial fishermen had harvested millions of crabs, which they used for bait while fishing for conch and...

By Jon Hurdle REED'S BEACH, New Jersey -- On a remote New Jersey beach, a team of biologists huddled behind a dune, out of sight of a flock of birds that gathered on a stretch of sand. Suddenly, there was a loud bang, and the scientists sprinted to a spot on the beach where a net, propelled by an explosive charge, trapped about 100 birds that were flapping their wings helplessly. Rushing to untangle the birds, the team released the sea gulls and then gently placed the other species -- all...

GALLOWAY TOWNSHIP, N.J. -- Environmentalists won a key battle Thursday in their efforts to protect the red knot, a small bird that migrates through the Delaware Bay. After a sometimes contentious meeting that pitted the state and environmentalists against fishermen who have plied the bay for years, the state Marine Fisheries Council - by a 7-3 vote - chose not to veto proposed rules from the Department of Environmental Protection that would implement a two-year moratorium on horseshoe crab...

TRENTON, N.J. -- Environmentalists on Tuesday will urge the governors of New Jersey and Delaware to enforce strong new protections for a migratory shorebird threatened with extinction. Eight conservation groups in the two states are rallying on behalf of the red knot, a species that migrates from South America to the Arctic to breed each spring. The birds' principal stopover is New Jersey and Delaware, where they spend weeks fattening up on horseshoe crab eggs before continuing their...
