Social factors affect vocal activity patterns of two common call types in Little Owl males

Popis výsledku v původním jazyce

Vocal communication plays a key role in behaviour of nocturnal avian species. The amount of specific vocal utterances changes depending on the presence and absence of the target audience and thus it can inform, among others, about possible function of the calls. In this study, we used a passive recording setup and counted all hoot and chewing calls given by focal Little Owl (Athene noctua) males in the presence or absence of other vocalising males and their female partners during one night to investigate possible roles of these two call types in inter- and intra-sexual communication. The total number of hoots increased in males with two or more male neighbours compared to those having a single or no male neighbour. Furthermore, the total number of chewing calls was higher in the presence of vocally active female. These results confirmed the presumed territorial function of hoots, but they imply that chewing calls, which were suggested to function in a broad array of different and even antagonistic contexts, are probably used in male-female interactions. The absence of correlation in the vocal output of both call types further supports different communication roles of hoots and chewing calls. We argue that local social environment (e.g. number of neighbours) rather than broad population descriptions (high/low-density population) appears to be more useful in similar studies. Our study also represents an important contribution to understanding of contextual changes in vocal activity in non-songbirds.
