LIVE! Watch Louisville's Great Horned Owls
Note: The owls have not returned to the box nest so although the camera is still active and we continue to monitor the nest we are currently not live streaming from that nest. If they return, we will once again provide a link to that camera. There are currently two eggs in the tree nest. The average incubation is 35 days and the first egg was laid on February 9th so we should see the first egg hatch on March 16th.

The Open Space Division has partnered with the Colorado Avian Research and Rehabilitation Institute (CARRI) to install 2 outdoor web cameras on select Open Space properties to view nesting activities of local raptors in 2019. The City of Louisville is excited to provide an opportunity for viewers to watch courtship, incubation, and feeding activities of great horned owls during breeding season. It’s going to be a real HOOT! 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 clever and adaptable species. They can be found throughout the United States from forests, prairies, to city parks.
- They may 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 active at night and most of 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 will stay in the same territories until the following year.
- Tree cavity nest: This great horned owl pair has occupied this nesting cavity during breeding season in 2015, 2016, and again in 2018. In 2015, one chick successfully fledged. In 2016, 2 chicks fledged. And, in 2018 3 chicks fledged.
- 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 City of
