In the spring of 2003, this osprey pair began nesting on a light pole at the Boulder County Fairgrounds and returned each year. In 2009, wildlife biologists moved the nest to its current location just east of the Cattail pond for the birds' safety. The pair shifted to the new location with ease. Our biologists believe that the local surge in nests may be offspring returning to their previous habitat area.
