In 2010, the Iowa DNR's Wildlife Diversity Program is initiating a new bald eagle territory monitoring survey. For many years we have kept track of eagle nests on an opportunistic basis, encouraging citizens and natural resources professionals to report anything that they could about eagle nests in their area. This approach has worked well but a few things have happened in recent years: 1) The number of nesting pairs in the state has grown exponentially making it more difficult to keep track of them, 2) the eagle was taken off of the Federal Endangered Species List, and 3) while eagles are doing very well they still face some old threats (habitat loss) as well as some threats recently brought to light (lead poisoning). For these reasons we would like to put into place a more standardized and comprehensive eagle nest monitoring plan that would help us keep a better eye on trends of bald eagle productivity and population.

The plan is simple. Fifty-four bald eagle nests have been randomly chosen to be monitored in a standardized and regular fashion (See Map,*pdf). These 54 were chosen from a list of territories that are known to have had some nesting activity in the last 3 years. Each of the chosen territories will be assigned an official volunteer monitor who will visit the nest 3 times during the eagle nesting season: once in the month of March, once in the month of May, and once between June 7 and July 7. On each visit the monitor will observe the nest using binoculars and/or a scope for 20 minutes. They will record activity and eventually how many young are produced and fledge. These observations will help us get a good estimate of how successful and productive eagles are across the state. It will also give us warning signs if something is going wrong.

Want to Help?

There are lots of ways to help!

BECOME AN OFFICIAL MONITOR: If you live near one of the 54 chosen nests and have some wildlife observation experience (binoculars and a scope are also handy) then maybe you'd like to become an official nest monitor! If you'd like to find out more please contact Stephanie Shepherd (contact information below).

REPORT ANY NESTING ACTIVITY: We will still welcome any other bald eagle nest reports. We are especially interested in the location and usage of new nests as well as updates on the usage and productivity (how many young produced?) of nests about which we already know. You can report this information by downloading and mailing in the instructions and datasheet below.

ATTEND A WORKSHOP: If you'd like to learn more about how to observe and record data on eagle nests you can attend a 6 hour workshop and become a Volunteer Wildlife Monitor. Check out our workshop schedules and information about the Bird Nest Monitoring workshops.
