Peregrine falcons, 2011

Peregrine falcons are now surprisingly common in urban areas. A nest is just a perch on a high cliff ledge, preferably south-facing, with an overhang. Tall buildings and bridges with similar ledges are favorite sites, too.

In 1989, a Northern States Power (now Xcel Energy) employee spotted a peregrine falcon hanging out around the stack of the Allen S. King plant in Oak Park Heights, Minnesota. The company installed a nest box, which quickly became home to a falcon named Mae. The nest box was a success, and the power company decided to provide nest boxes at nearly all of its Minnesota power plants.

This year, the King plant nest box is home to a female falcon named Belinda and a male named Brent. This is Belinda's eighth season at the King plant; two of her five eggs hatched early on Tuesday, May 24.
