Pelicans rescued from a 2010 oil spill, degreased and released in Georgia have returned 700 miles (1,126 km) to an island restored last year for pelicans and other seabirds.
The Louisiana Wildlife and Fisheries Department said in a news release Thursday that it was one of the 5,000 oil-covered birds collected inside and outside Louisiana during the spill and one of the 582 rehabilitated pelicans. Said that.
Biologists do not know when it returned to Queen Beth Island. However, a photo taken in March by a department biologist reveals a red band marked “33Z” around the bird’s leg at the Imperial Pier in Barataria Bay after the rescue on June 14, 2010. Is shown.
“It’s really impressive to be back from Georgia,” said Casey Wright, who found and photographed a pelican on a rocky pier on Queen Beth Island, which holds 15% to 20% of the pelican nests in Louisiana. Said. The acre (2 hectares) was high enough for a large bird to nest.
Currently, about 36 acres (14.6 hectares) are available for birds, the agency said.
After the bird rehabilitation, the spill was still ongoing, so the Pelican was flown to the United States Coast Guard station in Brunswick, Georgia. The well was uncovered until September 19, 2010. July 1, 2010.
Other birds released in Georgia, Texas, and Florida have been found in Louisiana, the agency said. The zoo holds 11 that could not be released.
“Brown pelicans, like most seabirds, are thought to be genetically wired to return to their born colonies for long-distance travel during non-breeding seasons. “We do,” said ornithologist Robert Dobbs. “It may be an oversimplified generalization, but reobserved data of striped pelicans often support that pattern.”
According to the agency, dead and live birds collected in Louisiana make up about 65% of the birds recovered throughout the Gulf of Mexico, and brown pelicans make up more than one-fifth of the total. It was. According to scientists, the U.S. Fish and Wildlife Service estimates that the spill killed 65,000 to 102,000 birds in 2016, but other estimates are much higher. Bird populations have returned to pre-spill levels.
