Dubuque County Courthouse falcon lays 1st egg of spring

A peregrine falcon roosting at the Dubuque County Courthouse has laid its first egg of the spring. The egg arrived at approximately 11:57 p.m. Monday, according to footage from the Dubuque County Falcon Camera posted to YouTube. A pair of falcons began roosting in 2016 at the courthouse, and Dubuque County Conservation staff built a box for the birds and placed it on a high ledge. Peregrine falcons normally lay two to five eggs, according to the conservation department. The eggs hatch within about 30 days. The activities of the birds can be viewed on the Dubuque County YouTube page under the live tab.
