Eagle Watch Program

When bald eagles begin nesting in the Marshfield area, auto mechanic Jonathon Wilson spends almost every Saturday and Sunday watching them. “I just get lost in it,” he said.

This is Wilson’s second year volunteering with Missouri’s Eagle Watch Program, started by MDC Scientist Janet Haslerig in 2018. She leads Missouri’s baldeagle monitoring program, an annual effort begun in 2007, shortly after the U.S. Fish and Wildlife Service removed the bird from the federal endangered species list. “After delisting, states were asked to monitor their bald eagle populations,” Haslerig said.

She soon felt the need for help with this task, noting that other states were training volunteers to monitor local eagle nests.

“It seemed like a good way to get people involved as well as reduce competing demands on staff,” she said.

To train volunteers quickly, Haslerig posted videos and documents online. Currently, she has 89 volunteers monitoring 285 nests. “But,” she said, “we have over 500 active nests, so we need more help, especially in the northwest part of the state, where wind energy development is ongoing.”

“During project planning, wind energy developers can make accommodations to reduce potential disturbance to nesting eagles, and local monitors can help document the progress of these reduction efforts,” Haslerig said.

Having trained, dedicated volunteers “is our first line of defense in detecting immediate, local threats,” she said.

Wilson, who enjoys watching the state’s bald eagle numbers grow, emphasized that it’s important to learn how to monitor correctly. “It’s easy to spook an eagle, and sometimes they never come back,” he said.
