The family of American Kestrels have all fledged and are no longer in the box. Check back next April for the 2019 nesting season.
American Kestrels are the smallest falcons that nest in North America. Their numbers have been declining, due to predation by larger hawks and owls, disease and habitat loss.
These little falcons readily take to nest boxes, therefore we have placed almost a hundred nest boxes for American Kestrels from south Boulder to North Fort Collins and up in the mountains around Estes Park.
The camera below, is in a nest box in Loveland. The camera is placed at the top inside of the nest box and faces straight down on purpose.
Falcons and hawks defecate by shooting their feces over the edge of the nest.
For generations, American Kestrels have evolved to nest in cavities, yet still defecate in the same manor as other falcons and hawks. If we had the camera on the side of the box, as we do with the Barn Owls, the camera would get covered with excrement and be of no use.
Therefore, we decided to make a very tall box and place the camera at the top looking down, so the camera would remain clean throughout the nesting cycle.
We would like to thank the City of Loveland and Rise Broadband for making this live video possible.
We have been working with American Kestrels for many years and have found a nest box size that we feel is very good for the birds, as it gives the young room to move around in the box and exersize their wings prior to fledging.
Our box dimensions are as follows....
Front: 11 x 16 inches Make the entrance hole 3 inches in diameter and cut it 1.5 inches from the top of the box on the front.
Back: 11 x 22 inches
Side : 11 x 16 inches
Side : 7 x11 and 9x 11 inches (Door on side of Box)
Top: 11 x 13 inches
Bottom: 11 x 9.5 inches
