Abstract We advocate assessing the reliability of signals
of aggressive intent by eliciting aggressive signaling from a
subject, giving the subject an opportunity to attack a model,
and testing whether the subject's displays predict a
subsequent attack. Using this design, we found that most
singing behaviors are poor predictors of attack in song
sparrows (Melospiza melodia). Laidre and Vehrencamp
(Behav Ecol Sociobiol, DOI 10.1007/s00265-007-0539-3,
2008) suggested altering our experimental design to make
the model more realistic; it remains to be seen whether such
design changes would change the association between
display and attack. Laidre and Vehrencamp (Behav Ecol
Sociobiol, DOI 10.1007/s00265-007-0539-3, 2008) also
suggested that the reliability of soft song, the one display
