Abstract
Abstract. We report the undescribed advertisement calls of Diasporus gularis and D. tinker from the Colombian Pacific region. The call of D. gularis is a “whistle” consisting of a tonal note with four harmonics emitted at a frequency range from 2.6 kHz (frequency 5%) to 3.0 kHz (frequency 95%) and a peak frequency of 2.8 kHz. The call of D. tinker is a “tink,” has a single peaked note with two harmonics, a frequency range from 3.2 kHz (frequency 5%) to 3.6 kHz (frequency 95%), and a peak frequency of 3.4 kHz. According to the call traits reported within the genus Diasporus, we propose that D. gularis and D. tinker are acoustically more similar to D. citrinobapheus and D. anthrax, respectively. However, due to the lack of a complete phylogenetic tree for this clade, we cannot hypothesize if the call similarities between these species owe to a close phylogenetic relationship or convergent evolution in similar habitats.
