Hypervigilance as an adaptive strategy to multiple risks in a songbird

GENERAL INFORMATION 1. Paper CitationHonza M, Capek M, Czyż B, Trnka A, Večeřová G, Samas P. XXX. Hypervigilance as an adaptive strategy to multiple risks in a songbird. Behav Ecol. XXX 2. Brief abstract This dataset contains behavioral observations and acoustic playback experiment data from incubating female Great Reed Warblers in two populations with different brood parasitism pressures. The data includes vigilance responses (head turns, head alerts, nest leaving) to playback of Common Cuckoo, Eurasian Sparrowhawk, and European Turtle Dove calls, as well as responses to naturally occurring vocalizations. The dataset supports analyses comparing threat-specific versus generalized acoustic vigilance strategies in host-parasite systems. 3. Originators Peter Samas Miroslav Capek 4.
