Per Josh: for the first time in at least 5 years, it appears we have nestlings at the peregrine falcon eyrie at Cathedral Spires! The breeding pair has been present and made attempts at nesting all those years but have not gotten this close to fledging a nest in that time.

Ornithologists across the Front Range have noted that migration and the onset of the avian breeding season seemed to be delayed by around 7-10 days this year, possibly because of the timing and amount of spring precipitation. The peregrines at Cathedral laid eggs later than usual. Because of that, their nestlings may not be ready to leave the nest by the time our usual seasonal closure would end, after July 31. As such, the closure this year will remain until at least August 15 (an opening of August 16). This should give the nestlings the time they need to finish development and leave the nest area.

The Cathedral Spires area, including Block Tower, Cynical Pinnacle, Snake Buttress, the Dome, Hall of Mirrors, Sunshine Wall, and Poe Buttress, are closed annually starting March 1 for raptor nesting. After careful monitoring of nest sites, Jefferson County Open Space opens certain areas of Cathedral Spires and maintain spot closures for active nests through July 31st. Check back periodically during times of closure for updates: jeffco.us/open-space/parks/…

Note, JeffCo Open Space has notified us that access to The Bishop and Poop Point (along with all the Cathedral Spires Area) currently goes across JeffCo OS land. Despite information in some guidebooks (published or soon-to-be-published), the entire Cathedral Spires area is subject raptor nesting closures. Please be aware of the hefty fines associated with failure to observe these regulations.
