Jaime will be evaluating multiple measures of habitat quality in order to identify areas of high quality barn owl breeding habitat in Napa Valley and inform which measures can be reliably used in other areas. Her research also aims to reveal potential mismatches between observed habitat preferences and fitness outcomes. Additionally, Jaime will be assessing the frequency of double brooding by barn owls and identifying which environmental and individual factors influence the probability of double brooding. This research will not only fill knowledge gaps pertaining to the frequency of double brooding in Napa Valley, but will inform a more accurate estimate of how many rodents barn owls are removing from vineyards and the surrounding landscape each breeding season.
