Birds living near airports do not show consistently higher levels of feather corticosterone.

ABSTRACT: Noise represents a threat to human and wildlife health, triggering physiological and behavioral challenges to individuals living close to sources of extreme noise. Here, we considered airport environments as sources of potentially stressful stimuli for birds and tested if those living near airports are under higher physiological stress than birds living in quiet sites. We used measurements of CORT in feathers (CORT_f) as a proxy of chronic stress. We evaluated 14 passerine and 1 non-passerine species, living near three Brazilian airports. We found that, across species, individuals with a better body condition had lower CORT_f concentration. At the species level, we found that CORT_f concentration was not consistently affected by airport noise. Comparing indivi
