From dark reddish to crisp white, and from heavily spotted to almost no spots at all, barn owls can exhibit a wide range of plumage coloration. In other regions, Barn owls have been shown to associate with different foraging areas based on their coloration, and this affects which rodents they hunt, but the effects and extent of color variation in managed winegrape vineyards ecosystems remain unknown. Laura’s research measured the extent of plumage variation and its relationships with habitats and the effects on predator-prey interactions in Napa Valley vineyards. Her research goal was to further our understanding of the effect of polymorphism on rodent pest control, which will hopefully assist farmers’ decisions regarding nest box placement relative to and the management of cultivated and uncultivated areas. After completing her MSc, Laura went to work for the Golden Gate Raptor Observatory.
