One potential way to decrease predation risk is flocking. Flocking may affect vocalization frequencies due to increased intra-flock communication needs, but also because vocalizations in large flocks may be less costly in terms of predation risk. In this study, I examined the relationship between mixed-species flock size and long range call rates generally and the effect on intra-flock and territorial call rates of the crested tit. The general methodology of the study was direct observation of crested tit flocks in natural conditions. Call rates generally and both intra-flock and territorial call rates were affected by mixed-species flock size. The results show that intra-flock communication frequency is positively dependent on mixed-species flock size, most likely due to increased needs for communication in large flocks. The results also suggest that crested tit territorial communication rates are dependent on mixed-species flock size. I suggest that this is due to the decreased predation risk in larger flocks.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted using Plone Publishing form by Henrik Murdoch (arhemurd) on 2013-01-23 13:07:18.217443.
