Download scientific diagram | Proportion of species possessing different categories of alarm calls used in this analysis. (a) Species recorded as having or not having a vocal alarm signal. (b) Species recorded as possessing only distinct alarm calls, only multi-functional alarm calls, both types, or the type is unknown. (c) Species with distinct alarm calls (either distinct only or having both types) that direct the call or calls to adults, to offspring, to both adults and offspring, or the intended receiver is unknown. from publication: Emu -Austral Ornithology Life history characteristics and alarm calling in Australian arid-zone birds View supplementary material Life history characteristics and alarm calling in Australian arid-zone birds | In prey species, it is often the case that individuals give alarms when they are threatened. In birds, such signals are frequently vocal signals that alert conspecifics to the presence of a threat. The responses to these calls by receivers may include fleeing to cover or | birds, Ornithology and Breeding | ResearchGate, the professional network for scientists.
