Downtown Aurora peregrine chick rescued after plunge into Fox River

A young peregrine falcon’s first flight nearly ended in the Fox River when the chick struck a bridge and dropped into the current in downtown Aurora. What could have been a fatal mistake became a rescue because volunteers, photographers, and falcon specialists were already watching the family closely and knew how to respond fast.

The birds had become a public fixture at Aurora City Hall after the city’s peregrine pair shifted from a nest box atop Leland Towers to a ledge on the office building near the river. Vixen, a five-year-old female fledged from a nest in Minneapolis, paired with Dave, a male fledged from a Chicago nest in 2020, and laid four eggs this spring. Two hatched on May 1, 2026, and two more on May 4, with the city installing a 24-hour Falcon Cam and launching a naming contest so residents could follow the chicks from hatch to flight.

By June 7, the first chick had fledged and was not seen again. By June 13, the last of the four young birds had left the catwalk area. The third chick, though, met the kind of urban hazard that city peregrines face every season: glass, concrete, traffic, bridges, and water. On June 9, during its first flight, it hit the bridge and fell into the river.

That is where the human network mattered. Earlier that same day, Mary Hennen, director of the Chicago Peregrine Program and a Field Museum bird collections manager, had talked through what local monitors should do if a chick got into trouble. Hennen has monitored Chicago-region peregrines for 25 years and has worked with the birds since 1989, part of a program that began in 1985 by introducing 46 captive-bred birds and later shifted from release work to monitoring nesting pairs. When the Aurora chick hit the water, that background paid off immediately.

The chick was struggling against the current, and a man jumped in to get it out before the river claimed it. The rescue underscored how modern peregrine recovery now depends on more than tall buildings and nest boxes. It depends on people who know the birds, watch them daily, and act with enough restraint and experience to save a juvenile without making a bad moment worse. In Aurora, that combination kept a fledgling alive long enough to keep learning how to be a peregrine.
