How do glucocorticoids influence stress responses? Integrating permissive, suppressive, stimulatory, and preparative actions.
This review considers recent findings regarding GC action and generates criteria for determining whether a particular GC action permits, stimulates, or suppresses an ongoing stress-response or, as an additional category, is preparative for a subsequent stressor.

The results lend support to the use of corticosterone as a rapid quantitative predictor of survival in wild animal populations and predicted overall population health during the 1998 El Niño famine and the 1999 La Niña feast period.
Elevated corticosterone in feathers correlates with corticosterone‐induced decreased feather quality: a validation study
Results provide evidence that elevated CORT is a causative factor in decreasing feather quality during molt, however, there remain technical details that suggest caution when interpreting data from CORT extracted from feathers.

Data indicate that changes in responsiveness of the hypothalamic-pituitary-adrenal axis to ACTH and AVT serve to downregulate corticosterone responses during chronic stress, and leads to the following hypothesis.
A consensus endocrine profile for chronically stressed wild animals does not exist.
