Kestrels are also known as sparrow hawks. They are the smallest falcon in North America and are great for day time rodent control. They have a larger family group and are at no risk to domestic pets. They are more territorial so their nesting is a bit more limited although their appetite makes up for it.
kestrels are cavity nesters. In urban environments they tend to nest in in-pruned palm trees. we see a lot of destroyed nesting people prune their trees during nesting season. Kestrels also nest in saguaros, hollowed out trees, and also take well to man made nesting structures if installed a over 20ft.
Rhey prey on small birds, mice, lizards, and insects.
Artificial habitat installations do not always mean each house will contain a family. It can take time for habitat to be restored due to long-term use of rat poison and the animal’s inability to find the nest, and it also depends on simple breeding and migratory patterns. When we install 7 nest boxes, we are looking for 2-3 to get residents. Each family can eat over 70 rodents a week for the entire spring season. Residency has been known to increase over time if food is available, and with a clean food system, other predators may start to increase, as well.
Integrating a natural pest management program does not mean you will get rid of every single rodent. Just as poison has not been getting rid of all of your rodents, the birds of prey will not either. This program has proven to work as a management system throughout many areas of the globe, and we have the same confidence that it will work just as well locally. Please be patient with the process.
No rat poison can ever be used on, around, or in the property while nest boxes are installed.
