When Chester Smith hired on as warden of Sundown Island 24 years ago at the age of 65, a handful of endangered brown pelicans had just begun nesting on the tiny isle in Matagorda Bay, between Galveston and Corpus Christi, on the Gulf Coast of Texas. 鈥淎t that time almost all the brown pelicans had been killed off by DDT thinning their eggshells,鈥 he recalls. That year Smith counted fewer than 10 pairs nesting on Sundown, a 60-acre island made of dredge spoils from the nearby Matagorda Ship Channel.
Over the next quarter century Smith tended the island and its birds like a one-man lifeguard, policeman, and master gardener. 鈥淚 patrolled it and done my best to ask people not to get out on the island, because they鈥檇 scare the birds off their nests and the young ones wouldn鈥檛 hatch,鈥 says Smith, a lean, gregarious retired oil refinery worker. 鈥淚 learned how to keep the fire ants under control. We planted native trees and brush. And over the years we figured out how to keep the island from washing away.鈥
Today, at 89, Smith can watch the fruits of his labor fly in low 鈥渂rown bomber鈥 squadrons over Matagorda Bay every day. Last year he counted 1,600 nesting pairs of brown pelicans on Sundown Island. 鈥淚 see them now up around Galveston; they鈥檙e nesting on South Deer Island and North Deer Island,鈥 Smith says. 鈥淵ou even see them in the Houston area! That鈥檚 something. And most of them, you can trace 鈥檈m back to Sundown Island.鈥
Thanks to the work of Smith and others like him, the brown pelican recently joined the bald eagle as one of the conservation movement鈥檚 signature achievements. In November 2009 the U.S. Fish and Wildlife Service (USFWS) officially removed the bird from the endangered species list. From its initial listing in the early 1970s, when it had been hunted and poisoned to near-extinction, the population has rebounded to more than 650,000 pelicans along the Atlantic, Gulf, and Pacific coasts.
The first step in the pelican鈥檚 comeback was the 1972 ban on DDT, the widely used pesticide that thinned eggshells, causing them to shatter during incubation. Even after DDT had dissipated in the food chain, though, pelicans needed safe shoreline nesting ground. That鈥檚 where wardens like Smith and 爆料公社 Texas鈥檚 Coastal Sanctuary Program stepped into the breach.
The oil spill reminded the world that the Gulf Coast, especially Texas鈥攚hich as 爆料公社 went to press had been spared the effects of the spill鈥攃ontains some of the world鈥檚 most important nesting sites and migratory stopover habitat. Every spring tens of thousands of reddish egrets, great blue herons, brown pelicans, roseate spoonbills, Forster鈥檚 terns, black skimmers, and royal terns fledge their next generation on more than 150 small islands between the mainland and large barrier islands. 爆料公社 Texas leases 80 of those tiny islands from the state and manages them as bird sanctuaries.
The Coastal Sanctuary Program constitutes one of the nation鈥檚 oldest and most successful conservation partnerships. Six of the managed sites have been designated Globally Important Bird Areas by 爆料公社 and BirdLife International. Last year the program won the USFWS 2009 Recovery Champion award in recognition of its critical role in the brown pelican鈥檚 recovery.
Since 1923 the patrol has kept watch. Today Smith is one of six Texas 爆料公社 coastal wardens who protect the birds鈥攁nd keep the islands, which are constantly scoured by waves and currents, from washing away. In a sense the pelicans, egrets, herons, and spoonbills are paying rent鈥攁nd the wardens are the building supers. 鈥淭he wardens let us know what鈥檚 going on out there,鈥 says John Huffman, Texas Coastal Program coordinator for the USFWS鈥檚 southwest region. 鈥淭hey鈥檙e the eyes and ears of the whole conservation community.鈥
Other states, notably Florida and North Carolina, also employ bird wardens. But during a recent journey through Texas鈥檚 Coastal Bend country, the thornscrub and prairie grass shoreline that stretches roughly from Galveston to the Mexican border, I discovered that Texas 爆料公社 wardens are a little different. They鈥檙e tough, irascible, and just a touch on the eccentric side. As they patrol the shallow bays and saltwater marshes of the western Gulf Coast, they carry a little extra Texas in their step.
Today鈥檚 bird wardens trace their lineage back to the late 19th century, when the plume trade drove many of America鈥檚 most magnificent birds to the brink of extinction. The fashion for feather-decorated hats fueled a commercial slaughter similar to that suffered by the Great Plains bison. In the early 1900s Congress and many states passed legislation defending birds, but without funding for enforcement, poachers largely ignored the laws. In response, local 爆料公社 societies began hiring hunters and boatmen as bird wardens鈥攁n idea that in 1903 led President Theodore Roosevelt to create the first federal bird refuge on Florida鈥檚 Pelican Island, the forerunner of today鈥檚 National Wildlife Refuge System.
Those early wardens were tough hombres. One job description called for someone 鈥渨ell acquainted with local conditions, a strong, fearless man and one fully alive to the value of bird protection.鈥 The most celebrated founding warden, a poacher-turned-protector named Guy Bradley, was murdered in 1905 when he confronted a gang of egret poachers in the Everglades.
The current generation carries on Bradley鈥檚 tradition, with one notable exception. They鈥檙e not all men. Smith鈥檚 success with the Sundown Island pelicans, in fact, was underpinned by the work of Emilie Payne, a legendarily tenacious warden. 鈥淪he was the first person to really get out and help the pelicans,鈥 Smith tells me.
Back in the early 1970s one of the region鈥檚 few remaining rookeries survived on a dredge spoil island in Corpus Christi Bay. It hosted a grand total of three nesting pairs. 鈥淭hey endured all kinds of disturbances back then,鈥 recalls Payne, a housewife who earned a biology degree while raising her family in Corpus Christi. 鈥淔ishermen, unleashed dogs, and boaters stopping to picnic. We even had flying students buzzing the island in their airplanes.鈥
Payne ran her skiff out to the island on weekends and holidays for nearly 20 years. She posted signs asking people to keep a respectable distance during nesting season. She cleaned up oil spills. She helped rehabilitate the pelican鈥檚 reputation among fishermen, who considered the bird a competitor.
Over time Payne saw the colony flourish. By the mid-1980s the pelican population had grown to more than 100 mated pairs. The birds began recolonizing former nesting grounds on nearby islands. 鈥淓milie was the spearhead,鈥 recalls Pat Suter, head of the Sierra Club鈥檚 Coastal Bend chapter. 鈥淪he is one determined lady. Their recovery is due in large measure to her persistence.鈥
By the time Payne stepped down from the job in the 1990s, the local pelican population topped 1,000. The birds kept expanding their territory, eventually finding Sundown Island鈥攁nd their next protector, Chester Smith.
鈥淚鈥檓 having a busy spring,鈥 Smith says. 鈥淚鈥檓 keeping an eye on this oil spill now,鈥 although in May the Gulf鈥檚 prevailing Loop Current was sweeping the slick east toward Florida, away from Texas. 鈥淎nd I鈥檓 working with the Corps of Engineers and the U.S. Fish and Wildlife Service to shore up Sundown鈥檚 erosion problems. But the birds are doing well. It鈥檚 exciting to see them all come in at the height of the nesting season in the middle of May. Makes you feel like you鈥檝e accomplished something.鈥
Farther down the coast, near Corpus Christi, David Newstead watches over an ever-changing collection of islands. And by change, he means wholesale. Waves and strong currents continually erode some established islands, while the Army Corps of Engineers creates new ones. 鈥淲e lose a lot more than we gain every year,鈥 Newstead tells me.
At 35, he is the youngest warden, but he鈥檚 the senior biologist among the corps. A trim man with a crinkly smile, Newstead wears three hats. He鈥檚 a staff scientist for waterbirds within the Coastal Bend Bays & Estuaries Program, a local habitat restoration organization; an 爆料公社 bird warden; and president of 爆料公社鈥檚 Coastal Bend chapter. 鈥淲e鈥檙e lucky to share David鈥檚 time and expertise with the Bays & Estuaries Program,鈥 says Bob Benson, executive director of Texas 爆料公社. 鈥淎s their scientist, his charge is the flora and fauna of the entire bay system, but he鈥檚 got such a strong natural affinity for birds that it works out well for all of us.鈥
On a blustery April day, Benson and I join New-stead on his weekly rounds. We hop on his boat and head out of Aransas Pass, a fishing town, past rusty shrimp trawlers and tumbledown bait shacks with hand-painted signs. As we motor into the wide shallows of Redfish Bay, a popular recreational fishing spot, brown pelicans glide low off our starboard rail. We pass a handful of islands no bigger than one-car garages. Signs appear here and there: 鈥淒O NOT LAND OR ENTER. Island closed during bird nesting season, February-August.鈥
Newstead spots a small flock of Forster鈥檚 terns setting on an island. 鈥淭hat鈥檚 a good sign,鈥 he says. 鈥淲e鈥檝e been watching this island closely. The problem here is keeping raccoons off the island.鈥 (They steal eggs.)
鈥淗ow do you keep them off?鈥 I ask.
鈥淗avahart traps usually do the job,鈥 Newstead says. 鈥淔ire ants are often a problem, too. If you don鈥檛 keep them controlled, they鈥檒l skeletonize a chick just as it鈥檚 breaking out of the egg.鈥
Newstead slows the boat as we approach Terminal Causeway Island, an 爆料公社-leased property fringed with black mangroves. 鈥淭his one鈥檚 starting to get cranked up,鈥 he says. 鈥淔ive years ago there wasn鈥檛 so much activity, but the birds are figuring out how to nest in the mangroves.鈥 Benson spots a handful of roseate spoonbills鈥攊t鈥檚 tough to miss their fiery pink feathers鈥攇reat blue herons, and cattle egrets nesting in the branchy shrubbery.
鈥淟ooks like we could use some signs out here,鈥 says Benson.
鈥淚t鈥檚 a tough call,鈥 says Newstead. 鈥淲e can鈥檛 put signs on every island. At a certain point you鈥檝e got to rely on people鈥檚 common sense. Hopefully seeing those heron nests is enough to let people know what鈥檚 going on here.鈥
Saving and protecting these nesting oases is becoming more critical as larger islands鈥攅specially barrier islands that have traditionally served as nesting grounds鈥攕uccumb to development. Dallas, Houston, and Austin were among the country鈥檚 fastest-growing cities in 2009. Many newcomers crave shorefront property and marine recreation. When beaches and estuaries turn into housing developments and quiet bays become popular weekend fishing spots, birds start to disappear. Researchers at the University of Texas at Austin鈥檚 Marine Science Institute recently found that between 1979 and 2007, the average number of people on the beach on Mustang Island, the barrier island off Corpus Christi, grew fivefold, from 19 to about 95. In that same time, 10 of 28 bird species suffered significant population losses. Forster鈥檚 terns, gull-billed terns, and black skimmers declined between 53 percent and 88 percent. Double-crested cormorant populations fell by 82 percent.
For many of Mustang Island鈥檚 birds, it wasn鈥檛 just habitat loss but the increased presence of humans that led to their disappearance. When people recreate on beaches and shoreline, they don鈥檛 always stroll quietly. They run. They shout. They throw Frisbees. Perhaps most alarming, in birds鈥 eyes, they let their dogs roam freely. Shorebirds don鈥檛 just need habitat. They need habitat with minimal human disturbance. 鈥淭hat human disturbance is often innocent, but it stems from ignorance,鈥 says Benson. 鈥淸Newcomers] aren鈥檛 familiar with the nesting islands and the general rules of the water down here. They see a tiny little island and they think picnic spot, not bird rookery.鈥
As nesting space continues to come at a higher premium, some Texas wardens have turned to business savvy and deal-making creativity to protect and expand nesting grounds. 鈥淭here鈥檚 a nice diverse rookery over in Nueces Bay,鈥 north of Corpus Christi, Newstead says. 鈥淏ut the material on the island is too claylike for ground nesting birds like gull-billed terns and black skimmers. And black skimmers are especially tough in terms of nesting encouragement. They鈥檙e real skittish. They鈥檒l sit at a site for a month before they鈥檒l lay an egg.鈥
Wardens have used sand-filled tubes, concrete rubble, and crushed shells to shore up islands. Through the grapevine, Newstead heard about a local seafood company that paid to have its oyster shells hauled to the dump. Then he found a glass crusher. 鈥淵ou chuck a five-gallon bucket of oyster shells into the hopper, and out comes the crushed material,鈥 he says, smiling. Earlier this year he and some volunteers laid down four tons of crushed shells, 鈥渁 nice, rough substrate,鈥 on the unnamed island. 鈥淚f it works, we鈥檒l have helped bring back those terns and skimmers, two of the most imperiled species on the coast.鈥
Like other wardens, Newstead is trying to anticipate the impact of the Deepwater Horizon spill on his region. 鈥淚t could affect us like a hurricane,鈥 he says. 鈥淚n the past we鈥檝e seen birds relocate to our area after a hurricane has wiped out their nesting habitat elsewhere. We could see that here. A whole bunch of new birds showing up on our island means we鈥檝e got to have room for them. That makes the management of our islands all the more critical, and gets us thinking about how we might be able to bring more habitat and new or reclaimed islands into play.鈥
My final stop is Arroyo City, a sleepy fishing town about 35 miles north of the Mexican border. That鈥檚 where I meet up with Leroy Overstreet. The 85-year-old may be the most colorful warden in the system.
鈥淚鈥檓 an outdoor person,鈥 he tells me as he fires up his outboard motor and pushes away from a county dock. Overstreet is a thin strip of rawhide in rubber boots, blue jeans, and a baseball cap. A half-smile crosses his face. 鈥淭he day I can鈥檛 get outside, I feel like kicking dirt in my face just to get a feel for it.鈥
A former ranch hand, rodeo cowboy, and mechanical engineer, Overstreet is equally experienced in the fine art of bar fighting (in his younger days), the complexities of U.S. patent law (he holds five patents for farm implements), and the rude business of varmint eradication (coyotes, beware).
鈥淭he nesting season鈥檚 running a little behind this year on account of this cold weather,鈥 he says, steering the boat up a channel toward Lower Laguna Madre. 鈥淏ut there are plenty of birds to see on Green Island.鈥
That鈥檚 where we鈥檙e headed. A 114-acre refuge located between the mainland coast and South Padre Island, Green Island shines as the jewel in the crown of the Coastal Sanctuary Program. It was 爆料公社鈥檚 first leased island back in 1923, when it housed one of the last extant nesting colonies of reddish egrets, one of the birds hit hardest by the plume trade.
Today 18 species of colonial-nesting waterbirds roost, nest, rest, and feed on its sandy shores and in its thick tangle of shrubs and trees. Reddish egrets, still the rarest North American herons, remain the island鈥檚 superstars. In a typical year 800 pairs of the spectacularly plumed birds鈥攎ore than one-fifth of the species鈥 worldwide breeding population鈥攔eturn to Green Island to nest.
It鈥檚 Overstreet鈥檚 job to keep them safe. That鈥檚 where a keen tracker鈥檚 eye comes in handy. 鈥淐oyote,鈥 he says, spotting a shaggy canine skulking in the brush along the side of a canal. They are the bane of the nesting birds. 鈥淚 see way too many of 鈥檈m,鈥 Overstreet tells me. 鈥淎 lot of my job is keeping coyotes from eating birds.鈥
There鈥檚 little love in his voice. He鈥檚 seen the damage coyotes can cause. 鈥淚 shot one a while back and opened it up to see what it had been eating,鈥 he says. 鈥淚 found 27 birds in its stomach. Twenty-seven! And these were birds that had been nesting in the islands.鈥 Shooting is a control method of last resort, and over the years Overstreet has exhausted other strategies. 鈥淭hey鈥檙e too smart for traps,鈥 he says. 鈥淩accoons will walk into traps, but a coyote won鈥檛 come near them.鈥 The government won鈥檛 allow him to use poison. So Overstreet is forced to guard the birds at gunpoint.
When we reach Green Island, Overstreet ties up the boat and leads me down a rickety dock that seems in imminent danger of collapse. This is disrepair by design. Along with predators, people pose a major threat to successful nesting on the coastal islands. Curious boaters, day-trippers, and fishermen are the usual culprits. A big warning sign helps people keep their distance during nesting season, and a broken-down dock deters them from coming ashore.
We pass over a mat of sargassum covering the beach and make our way up a trail into a thornscrub thicket. The ground cover is typically Texas: dry soil, agave, and prickly pear cactus under tough mesquite and spiny hackberry trees.
It鈥檚 a perfect nursery. I follow Overstreet up a set of stairs into a bird blind in the overstory. As we peer through cutout windows, the treetop world comes alive with colors so beautiful they put a little ache in your heart. On the eastern edge of the thornscrub, a clutch of roseate spoonbills prepare their nests. Here and there, great blue herons construct their sturdy thick-branched aeries. 鈥淭he white ibis you see over there, they鈥檙e spending the night but not nesting yet,鈥 says Overstreet. And everywhere鈥攐n every hackberry tree, at least鈥攁re reddish egrets. Their matted and shaggy cinnamon neck feathers look like the slicked-back hair of surfers after a hard session, and they yak away in their optimistic grunts.
Overstreet surveys the scene with a clinical eye. 鈥淲e鈥檙e not into full nesting yet,鈥 he observes. 鈥淚n a few weeks they鈥檒l all come in. Then when they hatch, we鈥檒l have somewhere near 8,000 birds here.鈥
Then he turns away to go scour the island for coyote tracks. There was a low tide last night, and Overstreet wants to make sure none of the varmints waded across. As long as he鈥檚 the warden, nothing鈥檚 going to threaten his birds.
