Ecological correlates of cortisol levels in two bat species with contrasting feeding habits

Highlights ► We investigate how feeding strategy and food availability affect cortisol secretion. ► Species with contrasting feeding habits show different cortisol patterns. ► Cortisol levels of vampires seem hardly be affected by food availability. ► Fruit abundance relates to cortisol levels in fr...

Summary:Highlights ► We investigate how feeding strategy and food availability affect cortisol secretion. ► Species with contrasting feeding habits show different cortisol patterns. ► Cortisol levels of vampires seem hardly be affected by food availability. ► Fruit abundance relates to cortisol levels in frugivores. ► Specialist vampire bats reach cortisol levels that are among the highest in mammals.
