Male song sparrows modulate their aggressive signaling in response to plumage signals: experiments with 3-D printed models

The paper tests how male song sparrows respond to 3-D printed models with different chest spotting patterns, finding that less spotted models elicit more aggressive signaling.

Are signals of aggressive intent less honest in urban habitats?

This study examines if aggressive signaling honesty changes in urban song sparrows, finding that urban birds maintain signal honesty despite higher noise levels.
