Unfortunately, the Great Horned Owls did not choose a nest with a camera in 2022. Check back next year! In the meantime, you can still see footage of past activity below.

Nesting Information:

The Open Space Division is continuing our partnership with the Colorado Avian Research and Rehabilitation Institute (CARRI) to provide viewing opportunities of local raptor nesting activities via outdoor web cameras on select Open Space properties. This year, staff observed owl activity at both owl nest locations early in the breeding season but, unfortunately, these nest sites have been determined inactive in 2021. We will continue to monitor the nest cameras and are hopeful we can provide another opportunity for viewers to watch courtship, incubation, and feeding activities of great horned owls during the 2022 breeding season. Below is some information on great horned owls: 

• Great horned owls are common year-round residents of Boulder County.
• Great horned owls are native to Colorado and are a clever and adaptable species. They can be found throughout the United States in habitats from forests, prairies, and deserts to city parks.
• They eat a variety of prey including crows, mice, lizards, and shorebirds; their favorite foods include rabbits and skunks.
• Like many owls, great horned owls are nocturnal and nesting activity will be best observed between dusk and dawn.
• Great horned owls nest earlier than most other raptor species and typically begin nesting in February and March in Colorado.
• Great horned owls do not build or maintain their own nests and frequently use abandoned nests of other birds or use tree cavities and nest platforms.
• Incubation begins after the first egg is laid, with the female providing most of the incubation while the male protects the nest from predators.
• Juveniles typically leave their parents in mid-summer but occasionally stay in the parental territory until the following year.
• Great horned owls are wild animals and may occasionally take domestic housecats and small dogs as prey. The City of Louisville will do its best to turn off the camera in case of such an occurrence.

The 3 owl chicks have successfully fledged the nest cavity and the camera has been turned off for the season.  Thank you for watching and we hope you enjoyed all of the exciting nesting activity this season!
