Nearly six months after the startling disappearance of a large population of birds from Audubon Park’s Bird Island, the rookery has yet to recover, and local birdwatchers are still feeling its loss.
“Our park patrons have a lot of personal and emotional investments in Bird Island,” said Sarah Burnette of the Audubon Institute. “The primary negative impact isn’t necessarily on the wildlife. It’s on the people.”
The large rookery in the center of the park’s lagoon drew a growing crowd of spectators until the birds mysteriously took off in early April, leaving behind their nests, including their eggs. Throughout the summer, theories for their abandonment included relocating for better food, disease, violent thunderstorms, and visiting film crews.
Lee Schoen, the curator of birds at Audubon Zoo, visited Bird Island last week. “It looks really abandoned,” Schoen observed.
To date, no single cause has been identified. Avian experts are still stumped, including Don Norman, a visiting biologist from Seattle who specializes in colonial waterbirds. “We don’t know whether the birds permanently left, but the colony failed,” Norman said, “and it did not re-nest.”
David White, a professor of biological sciences at Loyola University, thinks it’s still too early to assign blame, he said.
“There are just too many possibilities for why the birds disappeared,” White said. “Nature doesn’t always do something we don’t like simply because we did something bad.”
“Bottom line is, we don’t know why the birds disappeared,” Burnette said. “We walked the island on foot. Tried to figure out if it was predation, but couldn’t really definitively say one way or the other.”
In a park that has long served as a refuge from city life for New Orleanians, the loss has been keenly felt among local bird lovers. Visitors miss hearing the once familiar sound of birdcalls echoing across the park, Norman said. “Even if you don’t know the difference between a squirrel and a duck, you can hear it,” he said. “It’s just amazing.”
In the past, Bird Island’s population included great egrets, snowy egrets, cattle egrets, tri-colored herons, black-crowned night herons, anhingas, yellow-crowned night herons, and double-crested cormorants. The island’s inhabitants were wild, so they were not banded, tagged or identified, Burnette said, and no one knows for sure whether they will return. “We will have to wait until next spring, or late winter, to see whether the nesting birds will be returning,” said Peter Yaukey, a professor of geography at the University of New Orleans.
In the meantime, birdwatchers will continue to visit the urban oasis. Despite the abandonment of the island, “There are other interesting birds to be found in Audubon Park,” Yaukey said, “rookery or not.”
“The wildlife will persevere, whether it’s in the park or somewhere else,” Burnette said, but “the people who enjoy the park really miss seeing the birds.”
