2007 Peregrine Falcon Program Summary
In 2007, 24 nestling peregrine falcons were released over the course of three separate hacks. This effort marked the largest release of peregrine falcons from a single site in the species' recovery history. A 100% success rate was observed using the 14-day criteria, which is phenomenal given the number of falcons that were released. In fact, only two falcons dispersed before being on the wing for 30 days (i.e. 27 and 29 days). Additionally, one falcon from the 2006 release was observed in NERI for nearly a week before dispersing out of the area.
This year also marked the implementation of a solar powered video camera monitoring system, which was observable by not only NPS staff, but also the public from the Canyon Rim Visitor Center and from home via the internet. The camera system allowed NPS staff and the public to observe the falcon's development and behavior prior to and following the falcon's release.
