Kestrel Nest Box

I am going to build a kestrel nestbox today. I think it's important to provide the kind of places that encourage birds to thrive. I will leave it here when I go.

It appears that the state of Iowa has an American Kestral Trail along one of it's highway coridors, with a nestbox every mile:

In 1983 Ron Andrews of the Iowa Department of Natural Resources originated the interstate nest box program for American Kestrels. Working in cooperation with the Iowa Department of Transportation, nest boxes were attached to the backs of information signs along the interstate rights-of-way. Twenty nest boxes were placed on signs along I-35 in Northern Iowa that first year as an Eagle Scout project, and eight were used by kestrels. Nest boxes now occur nearly every mile of I-35 from Missouri to Minnesota. This corridor represents the nation's first statewide kestrel trail along an interstate system. These efforts have been coordinated by the Iowa Department of Natural Resources Nongame Wildlife Program and implemented at the local level by state nongame personnel, county conservation personnel, and a host of volunteers. Hundreds of nest boxes have been attached to highway signs elsewhere in Iowa. Many other states, including Rhode Island, Nebraska, and Idaho, have adopted the kestrel box program.

Information about programs like this can be found here. It says to hang the box from 10-30 feet in height. I prefer personally to stay below 20 ft, and given that the only two things in this desert that are 30 feet tall, saguaros and power poles, I think I'll just put it about ten feet up on a pole near the house.

I found this great plan here.
