Hello, I would like to thank you for the opportunity to register our observations about our dear neighbors Zack and Anima.
I would like to give a brief summary of what I am witnessing.
About 3 years ago I started noticing the appearance of several wild birds where I live.
I attribute this appearance to the massive destruction that has been taking place in the Brazilian Cerrado and Pantanal, with immense fires and illegal appropriation of protected lands.
I live in the city of Santos, State of São Paulo, Brazil. The city of Santos is extremely dense, vertical and still has the largest sea port in Latin America. Unfortunately, because of this, the city has high levels of pollution (air, noise and water).
Despite this, in 2020 I began to observe the presence of a very interested Kestrel couple on the balcony of our apartment, as if looking for a safe place to stay.
Later, I realized that they had nested in an extremely precarious spot on the facade of a neighboring building. Place of difficult entry and exit for birds and that could be accessed from the inside by poorly trained and/or ill-intentioned people.
That year (2020), I monitored the couple's activity from afar and started to study their behavior hoping that no malicious interference would happen. I could conclude that they had only one female nestling.
In 2021, with more experience and researching on this site, I built a nest box following the specifications and installed it on my balcony, along with a monitoring camera.
The couple, especially the female, was not very interested, despite frequenting all around the nest box.
In that year 2021 I could not identify the occurrence of nestling.
This year (2022) I had a surprise.
The male showed great interest by entering the nest box calling the female to occupy it. The female started to spend long hours on our balcony, sleeping, stretching and eating the food that the male started to bring.
They began to live a few meters away.
To my surprise, she proceeded to enter the nest box and spend some time inside, intensifying their activity on our balcony.
She went to sleep in the nest.
Now, on the 17th of September, I have identified a posted egg.
I registered the nest box on this site and I am collecting data to make it available to the community. I have several records of them, as they are very close.
I look forward to being able to collaborate and open to suggestions for reproduction, even in such an inhospitable place, with so many adversities, be productive for this beautiful species.
Marcelo, Santos, Sao Paulo - Brazil.
