Description: Although research on spotted owls (Strix occidentalis) has increased dramatically in the last decade, factors influencing owl reproduction still are poorly known. This ongoing study uses 9 years of demographic data to analyze associations between owl reproduction and weather, cone crop abundance, and nest-site structure. Initial results indicate no correlation between cone crop abundance and owl reproduction, but significant associations between owl reproductive success and spring weather conditions and nest-site structure.
