Build a Nest

Here’s how to build a Kestrel Nest:

The Kestrel Falcon normally nests in the holes on cliffs, buildings or in the Old crow’s nests.

It sometimes occupies a spacious semi-open nesting box, installed at the top of a tree or building (at least 5 meters high) but the nest must be water tight (water must not enter the nest!).
This nesting box must have a ledge, so that the eggs, and the babies are retained and not likely to fall out. It should also be equipped with an outside perch, a surveillance station for the parents as well as for the sight on hunting

Put a small layer of gravel (or sand/earth) on the ground.
