Since 2006, peregrine falcons have nested on the roof of the US Bank building in La Crosse. Each year, members of the Raptor Resource Center go to the roof and remove the peregrine chicks to band them.
When they do that, did you ever wonder - where are the adult peregrines? At US Bank, Dave Kester of the Center says, "they just circle in protest." But in other places, they'll do a fly by.
So, why do these people go to these lengths to increase the peregrine population? The answer, lies in history.
The peregrine is the fastest animal on Earth. For perspective, the cheetah, in bursts, will move at 65 to 75 miles per hour. John Howe of the Raptor Resource Center says in a dive, the peregrine has been clocked between 230 and 240 miles per hour.
