Counting birds on a beach in the Bahamas sounds like a dream vacation. But tallying populations of small species—in this case, Piping Plovers—is more of a feat than a fiesta. Volunteers must stand in the tide under the hot afternoon sun for hours at a time, sand whipping at their faces. They slog through wet mud flats with scopes and heavy cameras, constantly straining their eyes to scan for the creatures, keeping score the entire time.

But for ±¬ÁϹ«Éç North Carolina scientist Walker Golder, this back-breaking work is one of the most compelling parts of his job. Earlier this year, Walker and four other shorebird enthusiasts from ±¬ÁϹ«Éç, the U.S. Fish and Wildlife Service, and Bahamas National Trust scouted the Bahamas’ Berry Islands and newly minted Joulter Cays National Park during the 2016 International Piping Plover Census. The hemisphere-wide survey occurs every five years, and is a big deal for the little bird, which landed on the endangered species list back in 1985. (The is around 8,000 individuals.) Scientists from the Americas man different patches of the Piping Plovers’ wintering grounds for two weeks, counting the birds and assessing the health of their neotropical habitat.

When ±¬ÁϹ«Éç and the Canadian Wildlife Service teamed up for the last census in 2011, it was the first time the Joulter Cays—a small chain of undeveloped islands—was recognized as an official survey site. In less than six hours, the group, which included Golder and ±¬ÁϹ«Éç's Matt Jeffery, counted 100 Piping Plovers in the 50,000 acres of the Cays' habitat. It was a discovery that electrified many plover enthusiasts. The following year the team returned with reinforcements from BNT and spent several days combing the islands and sand flats in search of the shorebirds. This time they struck gold—326 Piping Plovers were found to have settled into the Joulter Cays for the winter (nearly 9% of the global breeding population rests there and in the Berry Islands each year), along with more than a dozen other species of birds. The data was enough to get 92,000 acres designated as a national park.  

Returning to the region is always exciting, and this year, Golder's team counted more individuals than ever—a total of 448 Piping Plovers between the Joulter Cays and Berry Islands. All together, 13 teams of researchers and conservation organizations in the Bahamas—comprised of U.S. scientists paired with local volunteers and students—tallied close to 1,400 plovers.

Marathon surveys like these can win protection for the plovers’ homes. Yet gathering the data requires a certain degree of toughness and diligence. In the Bahamas, life is unpredictable: Volunteers must always be prepared for bad weather, mechanical problems, and a general lack of cooperation from the birds. But as you'll see in the photos below, both the experience and the end results eclipse these challenges. Drift through the slideshow to discover how Golder and his crew ran this crucial census and gathered a better understanding of the life and future of the Piping Plover.

Band of Plovers

By Erica Langston

Ever seen a bird wearing an ankle bracelet? That’s no ordinary piece of bling: It’s a feather-light plastic or metal band that scientists use to track species of interest. By tagging an individual (here's ) and following it back and forth during migration, scientists and conservationists can collect crucial data about its life history. Take Piping Plovers for example. With the International Piping Plover Census only happening every five years, bands can provide more frequent data on the birds’ breeding and nesting sites, stopover areas, and habitat use. By outfitting the birds with the color-coded, brightly numbered, flag-shaped tags (they attach quite comfortably to the plovers' legs), scientists can tell individuals apart.

The flags are easy to spot for a reason: Researchers regularly ask beachgoers and citizen scientists to keep an eye out for banded birds and report their sightings. Just recently, Matt Jeffery heard that two Piping Plovers were photographed on the tiny island of Bonaire—the farthest south this species has ever been documented. While a pair of plovers in the Caribbean may not seem groundbreaking, it offers unique insight on just how far these tiny birds are willing to travel for the right habitat. Ultimately, the more eyes looking out for these beach bums, the more data available to aid coastal conservation.

These three banded Piping Plovers—all spotted during the latest census—have richly detailed biographies, thanks to repeated sightings. Let’s take a look at where they’ve been and what makes their stories so special.

Green YC6

Hailing from Rhode Island's East Matunuck State Beach, this lady in green is particularly special for USFWS ornithologist Pam Loring. She was banded by Loring last May, and has been spotted several times since then, along with a few new plover chicks by her side. But the best resighting came in January when Loring found YC6 during the Bahamas census. "It was a windy morning, and I just pointed my scope in a random direction and waited," she says. "Within about five minutes [the plover] flew in and landed in view. It was a really fortunate moment; it's amazing to think of how far she traveled to get there." 

Pink 69

Any plover that’s dressed in pink was caught and banded in the Bahamas. Out of all the plovers tagged there last year, 80 percent have been found again in the United States and Canada (you can follow their journeys on this map). Plover 69 earned its marker last year during an ±¬ÁϹ«Éç, Virginia Tech, and BNT expedition in the Bahamas. Records show that this bird is a loyal East Coast-er: It's popped up in Georgia, North Carolina, and most recently, the Joulter Cays.

Orange

Piping Plovers sporting an orange band are part of an endangered population that nests along the Great Lakes. A combination of habitat loss, nesting disturbance, and predation has left just about 77 nesting pairs in the region. This little guy's dramatic history dates back to 2014—the year when he lost his nest to the ocean and his mate to another male. He was first tagged in Michigan, and rediscovered in the Berry Islands last year. The census team found him on the same beach again this January.
