Data for: Snake-like bird hisses induce anti-predator responses in a frog

Sound playbacks were conducted in July 2022 and June 2023 at a tropical forest stream, Wuzhishan National Nature Reserve (109°32'-43' E, 18°48'-59' N), Hainan, south China. In playback experiments, a speaker (Clip3, JBL, USA) was fixed on a shelf bracket and placed at a 1 m distance to the focal individual. All stimuli were played via a digital voice recorder (ICD-PX470, Sony, Japan) connected to the speaker. During playbacks, the sound pressure levels (SPLs) of different groups were about 80 dB in the 1 m distance.
