Nearly a quarter of a century after the Exxon Valdez crashed and spewed 11 million gallons of crude into Prince William Sound, one species of seabird still has not recovered from the disaster. To help it recover, the federal government is proposing to get rid of lots of American minks. Allow us to explain.
Thousands of pigeon guillemots were killed by the Valdez disaster — some coated with oil, others poisoned by it for a decade afterward. The guillemots are the only marine bird still listed as “not recovering” from the accident; the local population is less than half what it was before the spill.
The birds used to flourish on the Naked Island group in the middle of the sound, but fewer than 100 remain there now. To boost that number back up to the pre-spill level of 1,000, the U.S. Fish and Wildlife Service is proposing to trap most of the islands’ American minks — aquatic ferret-like creatures that feast on the birds’ chicks and eggs. If trapping doesn’t work, shooting the minks is the backup plan.
