Abstract

•We examined the function of, and plasticity in, nest departure calls of female song sparrows.•Our results suggest that nest departure calls function to promote male nest guarding.•Females appear to balance costs and benefits when plastically adjusting calling rate.•Females called more when the male was present, increasing benefits of calling.•Females called less in the presence of a predator, reducing costs of calling.
