American Kestrel Breeding Productivity

In winter 2014, we installed 10 American Kestrel nest boxes on fence post in the western portion of the Reserve. These boxes were occupied by 6 pairs of kestrels which produced a total of 15 fledglings. The results of our project were summarized in a report by Cami Vega (Reserve intern), Steve Simmons and Chris Swarth and later a short paper was published in the Journal of the Central Valley Bird Club. In winter 2015, we added 20 more boxes. As of June, 15 of the 30 boxes were occuped by 16 pairs. According to graduate student Joy McDermott who is studying this population for her masters degree, 44 nestlings have been banded.
