We have no idea how many eggs Hattie will lay in this year's clutch (group of eggs). We can officially announce the start date of the 2023 falcon nesting season in Rochester, MN!! The first arrived yesterday morning, and now we wait and see how many other eggs will join this first one. The entire Mayo Clinic Peregrine Falcon team will continue to monitor the fledglings through July, before they become fully independent and leave their natal territory in late summer. Mayo Facilities staff are a critical part of recovering grounded falcon fledglings and coordinating their return.

The challenge of fledging includes inexperience in coordinating their flight in strong winds, recognizing the dangers of glass windows and walls, and getting off the ground if they land there. Obviously, the nestling doesn't cognitively think all of these things out, and things happen when they happen. A few days' time can make a significant difference in feather growth, and the more fully developed the feathers are, the better control the fledgling has during flight. The longer the nestlings stay in the eyrie (nest), the higher the chance of success for flight. Be aware that flight isn't an instant skill or knowledge but rather something mastered through observation and practice.
Sometimes it is a strong incentive for food, which means a deadly mistake if a nestling is only 30 days old. There are many variables involved with fledging and sometimes it is just luck of nature: it can be a chosen choice to fly or an accidental nudge by a sibling. The fledglings may or may not return to the box with any consistency once they fledge, but often, at least one bird is in or near the box for at least a week or so after fledging.
