Frequency and synchronisation features of a highly overlapped duet changes according to the context
(2019)Territorial defence and maintaining contact are two hypotheses of duet functions. Nevertheless, the acoustic characteristics of duets in these contexts have been poorly quantified. This work aimed to compare the spectrotemporal ... -
Geographic variation in the duets of the Rufous-naped Wren (Campylorhynchus rufinucha) complex
(2020)Acoustic signals used in animal communication play a key role in mate attraction, species recognition, and territory defense. Variation in acoustic signals may reflect population structure, lack of gene flow, and phylogenetic ... -
