Abstract
We explored rhythmic variation in acoustic signals by geography across four species of Picoides woodpeckers. We hypothesized that there would be an effect of geographic location on the cadence of drums and rattle-type calls. No significant effect was observed. However, drum cadence was observed to significantly impact conspecific recognition in playbacks.
