Squirble2.wav — zimbot
A whistle that quickly changes pitch; to the human ear it can be similar to a bird chirp, but birds are not likely to be fooled. Totally synthetic, created in Cool Edit Pro. This one sounds almost like a cassette tape being fast-forwarded or something similar. CC BY 4.0 by zimbot. Duration: 0.49s. Sourced from https://freesound.org/s/122269/.
