Try chasing a wild chick on a windy Rhode Island beach and you'll quickly learn two things. First, sand makes terrible running terrain. Second, those clumsy-looking young shorebirds can move surprisingly fast.
At Trustom Pond National Wildlife Refuge in South Kingstown, biologists recently spent an afternoon sprinting after two American oystercatcher chicks. One scampered into a salt pond, while the other took to the sky. "There is a problem. They can fly," joked Alan Kneidel, a senior conservation biologist with Manomet Conservation Sciences. When the team eventually caught them, they wrapped the football-sized birds in white pillowcases, carried them to a sand dune, measured them, and clipped colored identification bands onto their long legs.

That scene represents a quiet miracle unfolding along North American coasts.
While broader North American shorebird populations face sharp declines, the American oystercatcher is pulling off a dramatic recovery. Between 2008 and 2023, American oystercatcher numbers jumped 45% across Atlantic and Gulf coasts. That rebound didn't happen by accident. It took fifteen years of coordinated effort, ten million dollars, and thirty-five partner organizations across sixteen states working together to fix a problem that almost drove these birds out of New England entirely. Related reporting on this matter has been shared by The New York Times.
Here is how scientists, conservation groups, and everyday beachgoers managed to turn things around for one of North America's most recognizable coastal species.
Why American Oystercatchers Almost Disappeared
By the start of the 20th century, human activity had nearly wiped out American oystercatchers across New England. Unregulated hunting and aggressive egg collecting stripped beaches of breeding pairs. Even after federal protections halted direct hunting, modern pressures replaced historic ones.
Beach development destroyed native sand dunes. Off-leash dogs chased nesting adults off their eggs. Coastal predators like raccoons, skunks, and gulls multiplied near human communities, preying heavily on eggs and vulnerable chicks.
Oystercatchers make easy targets during breeding season. They don't build elaborate nests in trees or deep burrows. Instead, they scrape out shallow depressions directly in sand, gravel, or shell wrack along open beaches.
That ground-nesting strategy leaves their eggs completely exposed. When humans walk nearby, parent birds fly off the nest to draw attention away from their young. Leave those eggs unattended under a blazing hot sun for even twenty minutes, and the embryos inside overheat and die. Leave them exposed to a hungry raccoon, and they're gone in seconds.
Researchers soon realized that low chick survival was driving the species' steep drop. The birds were simply failing to raise enough young to replace adult mortality.
Inside the Ten Million Dollar Coastal Revival
Saving the species required a massive shift in tactics. Rather than using a one-size-fits-all rule, conservation leaders formed the American Oystercatcher Working Group. Led initially by the late Manomet conservation biologist Shiloh Schulte, the coalition conducted aerial surveys and mapped breeding locations along the entire coast.
Biologists realized each stretch of shoreline presented unique challenges. On one beach, unleashed pets were the main issue. On another, storm surges washed away nests, or high predator numbers wiped out every clutch of eggs in a single week.
Partners began tailoring local solutions to tackle specific threats:
- Predator Exclosures: On Martha's Vineyard, conservationists put up seasonal chicken-wire fencing around key nesting areas. The barriers kept skunks and raccoons from reaching eggs, helping drive a 77% surge in local breeding pairs since 2009.
- Shared Protections: Oystercatchers benefited directly from existing federal protections for piping plovers, another endangered shorebird. During plover nesting season, beach managers routinely ban off-road vehicles and restrict dogs on critical stretches of sand.
- Public Education: Educational signs and volunteer beach stewards informed visitors where birds were nesting. Simple string-and-stake boundaries marked off nest zones, letting humans enjoy the water while giving parent birds enough room to sit on their eggs.
Maureen Durkin, a federal wildlife biologist at the Rhode Island National Wildlife Refuge Complex who leads local banding efforts, highlighted the power of this focused coordination. She noted that the bird's recovery demonstrates how much groups can accomplish when they unite around clear goals and stay committed over the long haul.
What Makes These Shorebirds Surprisingly Adaptive
It helps that American oystercatchers possess a trait every surviving species needs: grit.
These birds are built for tough environments. With thick, peach-colored legs and long, chisel-shaped orange bills, they specialize in popping open hard-shelled mollusks. An oystercatcher can jam its bill into a slightly opened mussel or oyster shell, sever the adductor muscle in a split second, and scoop out the meat inside.
They aren't overly picky about habitat either when forced to improvise. Ted Simons, a retired professor from North Carolina State University who began studying oystercatchers in 1995, points out that the species is far more flexible than scientists initially thought.
Where natural beaches are crowded or eroded, American oystercatchers have adapted by nesting on flat, gravel-covered rooftops in coastal cities. Similar adaptability appears in related oystercatcher species overseas, which nest in agricultural pastures and even inside roadside potholes. That natural resilience gave conservation efforts a massive boost.
Rising Seas and Fresh Challenges Ahead
Success doesn't mean the job is finished. Climate change poses a growing threat to coastal birds across the Atlantic and Gulf coasts.
Sea level rise is chewing away at barrier islands and lowering beach elevations. High tides and severe spring storms regularly wash over low sand dunes, destroying entire nests during peak breeding season.
To counter this, wildlife agencies are trying new approaches. In Georgia, biologists are building elevated nesting pads and constructing artificial islands out of dredged sediment to give shorebirds safe ground above rising waters.
At the same time, shifting legal protections for wildlife habitats create ongoing uncertainty. Keeping oystercatcher numbers steady will require continuous habitat management and long-term public support.
Practical Steps Beachgoers Can Take Right Now
You don't need a biology degree to help shorebirds continue their recovery. Simple changes in beach etiquette directly impact whether young chicks survive the season.
- Keep Dogs on Leash: Even well-behaved dogs look like apex predators to nesting shorebirds. Keeping pets leashed keeps parent birds on their eggs.
- Respect Fenced Areas: String fences and signs aren't there to ruin your beach trip. Give marked nesting areas a wide berth so parents don't flush from their nests.
- Pack Out Trash and Food Scraps: Leftover food attracts gulls, crows, raccoons, and foxes to the beach. These animals quickly find and eat nearby bird eggs.
- Walk Near the High Water Line: Stick to wet sand when walking or running along the beach during late spring and early summer to avoid stepping on well-camouflaged nests.
