In non-cooperative breeding species, dominant individuals have lo[...]
Article
Clare Parker Fischer, Auteur ; Maren N. Vitousek, Auteur ; L. Michael Romero, AuteurMeasuring corticosterone (Cort) in bird feathers has become increasingly popular as a non-invasive method of obtaining an integrated profile of Cort exposure during the period of feather replacement. Most studies use antibody-based assays to ass[...]
Article
Clare Parker Fischer, Auteur ; Rohan Rao, Auteur ; L. Michael Romero, AuteurIn birds, the steroid hormone corticosterone (CORT) increases in response to real or perceived threats to homeostasis. A long-term record of CORT exposure is recorded in feathers when the hormone is incorporated into the keratinized tissue, and [...]

L. Michael Romero, Auteur ; Denver W. Holt, Auteur ; Julie L. Petersen, AuteurDans Ardea (97(4) 2009)Long-eared Owls Asio otus were flushed and captured from communal winter roosts and nesting seasons to assess both initial and stress-induced corticosterone concentrations. We examined blood samples from 16 males and 8 females in the winter, and[...]
