DES MOINES, Iowa (AP) – The Iowa Department of Natural Resources says it will release nine young ospreys at two spots as part of an effort to build a sustainable population of the birds. The DNR says the 42-day-old birds will be released in the next few weeks at Mud Lake, along the Mississippi River north of Dubuque, and Swan Lake, near Carroll.

The young birds of prey can tear apart fish but aren’t yet able to fly. The DNR says residents of Dubuque and Carroll counties can help by donating fresh fish for the birds. The ospreys will begin flying in a couple weeks and should quickly become self-sufficient.

The osprey release is part of a program to establish the birds in Iowa. Since 1997, 247 ospreys have been released at a dozen sites.
