Abstract

•We tested responses of smooth-billed anis, a joint-nesting bird, to two types of alarm call: chlurp and ahnee alarms.•Anis tended to produce chlurps in response to aerial predators and ahnee alarms in response to terrestrial threats.•In playback experiments, anis hid in vegetation after chlurp stimuli, and flew up after ahnee alarm stimuli.•Ani responses were consistent with evading attack by aerial (chlurp) and terrestrial (ahnee alarms) predators.•Both calls meet the requirements (production specificity, context independence) of functionally referential signals.
