How is the behavior of kestrels in the incubation of eggs ?

Hi!  I am monitoring a couple of Kestrels and they are adopting the following behavior:

There are three eggs in the nest box. During the day the male sometimes takes care of the eggs inside the nest box.  The female is outside the nest box sleeping and enjoying the movement from the top of my balcony.  For 11 days the female slept in the nest box. Now, it's been 4 days since she's slept in the nest box, leaving the eggs alone. 

Is this behavior normal? 

When does the hatching period start and how is it carried out? 

Could anyone give some information?

Thank you very much for your attention. I have difficulties with English, but I will make an effort to look for all the information, as the Kestrels have made many friends here and we are anxious for the species to be able to reproduce.Thank you very much for your attention.

Olá -

What you've described sounds typical so far. Breeding season starts with the male kestrel staking out a territory and identifying several potential nest sites; the female then arrives and selects the final nesting location. The female then lays one egg at a time over a period of several days until the entire clutch is laid, usually 4–5 eggs. The parents usually don't begin to incubate until several eggs have already been laid to ensure that all the eggs hatch within a few days of one another, which is likely why the female is staying out of the box recently. From the time the parents begin incubating the eggs, it should be about 27–31 days until the eggs hatch.

Hope that answers your questions, and let us know if you have any more. We're excited to hear what happens with this nest.

Thank you very much for the answers, its helped us a lot.I equipped the Kestrels' environment as 2 monitoring cameras and I have a lot of material from them in photos and films.I also installed, near the nest box, a monitoring station for temperature and air humidity, as I have been observing the occurrence of atypical temperatures for this season of the year, in addition to very sudden changes in weather with large variations in temperatures in a very short space of time. I hope that the collection of these simple data will help to understand why the species is reduced and how we can work to help it. It will be a great pleasure to share with you all the information, not only through the reports, but also in this forum.Thank you one more time ! Marcelo - Santos - Brazil
