Feather corticosterone reveals developmental challenges in a long‐term study of juvenile northern spotted owls

Ashlee Mikkelsen, Katie Dugger, Kathleen O'Reilly & Damon Lesmeister
1. Corticosterone is a steroid hormone integral to a variety of physiological pathways and is strongly associated with the vertebrate stress–response. In avian species, circulating corticosterone is sequestered into developing feathers and is used as an indicator of energy allocation during feather growth and widely applied in conservation physiology. 2. The northern spotted owl (Strix occidentalis caurina) is a federally threatened old–growth forest obligate of conservation concern endemic to the Pacific Northwest of the United...
