There are concerns, of course, about the danger to the community and livestock. We are trying to find their movement pattern.

You could look for hours at that sheer cliff trying to see a little hole in it. You're better off watching for the adults on the wing or checking with the visitor's center on nest locations.

We are trying to make it more friendly for law enforcement to make arrests and more friendly for the community to report these types of incidents.

They prey principally on small birds they catch on the wing, and Zion has a really good food source and good nesting sites for these falcons.

The worry we have then is if adults come charging. No one wants to get a talon in the back of the neck.

Zion is considered a core population area for the peregrine falcons. This area probably produces more young birds for dispersal outside the park than come into the park.
