Eastern Screech Owls are small cavity nesting owls found throughout the central and eastern parts of Colorado. 

Members of CARRI have been constructing and placing nest boxes for Eastern Screech OWls. Over the years, we have had several active nest. Unfortunately, they are all too far from human habitation to have live cameras on, so the videos (below) are from trail cams near one of our nests.

As of March 18th, 2019, we have a single active Eastern Screech Owl nest box. You can see the owl peering from the nest box entrance.


Things we have found through our research:

 1) In Northern Colorado, Eastern Screech Owls begin nesting in March and the young fledge in May.

2) When nesting in a natural cavity, Eastern Screech Owls seldom fledge more than three young.

3) Eastern Screech Owls from our nest boxes, preying upon voles, crayfish, American Robins, Northern Flickers, House Sparrows, Mourning Doves and Red-winged Blackbirds.

4) Incubation for Eastern Screech Owls lasts roughly 30 days and the young remain within the nest for about a month.

5) Unlike other owls, Eastern Screech Owlets frequently fledge on the same evening and spend time perched side by side, once out of the nest.

6) After the owlets have fledged, the adults will, occasionally, hunt during the day to feed them.
