Male Birds Sing for Their Fertile Female Neighbors Too: A Song Meter Case Study

Male Birds Sing for Their Fertile Female Neighbors Too: A Song Meter Case Study

While most bird studies on sexual signaling have focused on between-pair interactions, Conor Taff has instead looked outward.

Taff, whose research has just been published in Proceedings of the Royal Society B, deployed 5 song meters across multiple territories to study male calling behavior in relation to the fertility of female birds in neighboring territories. His findings suggest that birds' sexual signaling behavior is much more complex than we may have thought.

Taff’s paper, Fluctuations in Neighbourhood Fertility Generate Variable Signalling Effort, discusses how male common yellowthroats adjust song production in response to changes not only in within-pair social contexts, but also to changes in the fertility of neighboring females up to 400 meters away.
