DNR investigating deaths of 2,200 gulls near Brainerd

The Minnesota Department of Natural Resources is investigating the deaths of about 2,200 young ring-billed gulls around a popular lake near Brainerd.

DNR area wildlife manager Gary Drotts says he got reports late last month of about 400 dead birds on Gooseberry Island in Pelican Lake, a popular beach and resort area.

Drotts and a crew arrived to find many more dead birds than expected. He said there was also a small number of dead herons and cormorants.

DNR scientists are investigating the cause of death. The agency says bird die-offs are not uncommon in summer and are usually caused by botulism or West Nile virus.

The department says neither the botulism nor West Nile virus are a threat to humans or livestock when occurring in this manner.

Drotts says the bird corpses were incinerated.
