Anglers, Boaters Stay Clear of Coastal Waterbird Rookeries

AUSTIN – With spring approaching, iconic coastal birds like brown pelicans, roseate spoonbills, black skimmers, and reddish egrets are starting to build nests, lay eggs, and raise their young in colonies on small, inshore islands along the Gulf Coast of Texas. The nesting islands, or rookeries, often support thousands of birds that utilize all available island habitat. The Texas Parks and Wildlife Department is cautioning Texas boaters and anglers to watch out for nesting birds, which are particularly sensitive to manmade disturbances.

“Waterbirds, and the habitats they call home, are extremely valuable to Texas,” said TPWD diversity biologist Trey Barron. “The reddish egret, a charismatic coastal specialist and state threatened species, attracts visitors from all of the world who come

Of the 25 or so species considered to be colonial in Texas, over half are experiencing major population declines. Colonial waterbirds typically nest from late February through August when recreational use by coastal anglers and boaters is highest, putting them at greater to see it dancing in the shallow waters chasing food. More reddish egrets nest in Texas than just about anywhere else in the world.”

Disturbance by humans can often lead to nest failure and, in some cases, complete abandonment of an island.

“When approached too closely by boaters or people wading nearby, birds are frightened off their nests, leaving eggs and chicks exposed to rapidly overheat in the summer sun and allowing opportunistic predators like gulls and grackles to quickly swoop in and feed on them,” said Barron. “With too many disturbances, an entire colony of thousands of birds may abandon an island and give up on breeding for the year. Over time, this can potentially lead to drastic population declines.”

The Texas Colonial Waterbird Society, a large partnership of federal and state agencies, universities, and non-profit organizations has conducted an annual survey since the early 1970s to track waterbird populations and island conditions. The survey data is used to help establish population goals and identify management needs. Some member organizations actively manage the islands to improve habitat, restore acreage lost to erosion and storms, and place protective signage along shorelines to identify rookery islands to boaters and anglers.

Colonial waterbirds and their nests, eggs, and chicks are protected under the federal Migratory Bird Treaty Act and by Texas Parks and Wildlife Code. The Texas Colonial Waterbird Society recommends that people fish, swim, and play from 50 yards away from rookery islands to minimize unintentional and potentially illegal disturbance.

In addition to avoiding rookery islands during the nesting season, it’s important for coastal boaters and anglers to properly dispose of fishing line, tackle, and other waste to ensure that no birds, turtles, or other marine life become entangled, injured or killed.

“The habitats that waterbirds use are the same habitats in which we, including myself, enjoy fishing, hunting and photographing wildlife,” Barron said. “We just have to remember to give them their space, especially during the nesting season, and pick up after ourselves. If you’re out on the water, look for the yellow signs that identify rookery islands and keep your distance. We can all enjoy the same places as long as we do it responsibly.”
