A pair of peregrine falcons have returned to a nesting site in Franklin County, Missouri, signalling the start of another breeding season that could bring more chicks to the region. The birds have claimed a nest box monitored by Ameren Missouri and the nest is shown live online. Biologists believe these early signs indicate a promising season for the birds, which have rebounded in parts of the country but remain vulnerable in Missouri. The Falcon Cam gives viewers a rare and authentic look at the birds' nesting process.
