Yearend Eagle Monitoring Report

Saturday, January 13, 2018 was the annual reception for eagle monitors and the public to get an update on the status on the eagles in the Fox Valley. Some of the interesting things we learned include:

  • Eagles can see a fish under water from one-half mile away
  • Eagles are territorial for approximately a one-half mile radius around their nest during nesting, but not so intolerant of other eagles after the eaglets have fledged
  • Primary reason for decline in eagles has been:  logging, reduction of food source, predators and DDT
  • New River Alliance citizen science monitors began working with the WDNR’s Bald Eagle Program in 2009.
  • In 2017 the Fox Valley accounted for 176 eagle nests.
  • 2017 was a record year. There were 1590 Bald Eagle nests in Wisconsin.
  • Wisconsin’s Eagle Data Area 2 had the highest count of eagles in North America (includes Vilas and Oneida counties)
  • Since budgets have cut, the Bald Eagle Program depends heavily upon the WDNR Donation Fund called Adopt an Eagle Nest Program administered by the Bureau of Natural Heritage Conservation
