The Minnesota Department of Natural Resources says a second round of testing indicates migrating pelicans picked up oil spill contaminants in the Gulf of Mexico.
Earlier testing found contaminants in pelican eggs. A new round of tests on bill knobs, which pelicans shed each year, found oil related contaminants in three-fourths of the birds tested. Oil dispersant chemicals were found in one-third of the birds.
“Now that we know that’s present it’s going to raise some questions about what might this be doing to the population of pelicans in the long term in terms of reproductive success or longevity or hatchability of the eggs,” said DNR non-game wildlife program supervisor Carrol Henderson.
He said the test results don’t definitively prove pelicans were contaminated by the Deepwater Horizon oil spill.
“One of the aspects of good research is not to jump to conclusions,” Henderson said. “We’ve got some really interesting results starting to come in. But we need to continue this work before we draw any conclusions on what the long-term impacts might be.” [...]
