Four bald eagles have been shot dead in Minnesota since April, prompting wildlife officials to open forensic investigations and offer a reward for information leading to convictions for killing the federally protected birds.
The U.S. Fish and Wildlife Service (FWS) said Tuesday that an eagle was apparently shot in October on the Leech Lake Indian Reservation — the fourth such shooting known to have occurred this year. In April, three others were found shot along a county highway near Cook, Minn., and a separate criminal investigation is underway. All four carcasses were sent to the FWS laboratory in Ashland, Ore., for forensic analysis on the type of bullet and other information, wildlife officials said.
Now a reward of up to $2,500 for information that leads to the conviction of any responsible party is being offered, officials said Tuesday.
Officials with the wildlife service refused to discuss possible motives, suspects or other information developed in the investigations so far.
Such incidents are unusual in Minnesota. There have been 67 eagle shootings since 2001 in the eight states that make up the wildlife service's Midwest region, said Deanne Endrizzi, a biologist with the agency.
Such killings almost always result in investigations because bald and golden eagles are among the birds protected by federal laws that go back to 1900.
Once listed as endangered, when their numbers dwindled to an estimated 417 nesting pairs in the lower United States, eagles have recovered to about 70,000 individuals in North America, according to some estimates.
Minnesota has one the largest eagle populations in the Lower 48 states, with about 10,000 pairs, according to the Minnesota Department of Natural Resources (DNR).
