Some creatures chirping at night, with city ambient noise in the background. I don't know if they are birds, or bats, or what. I stayed at my grandmother's place for a few days, where these creatures are heard every night, but no one ever saw them to be able to identify them. Recorded with a Zoom H4n portable recorder, on the balcony in my grandmother's apartment.<br/>夜間chirps01.flac<br/>聲道：2<br/>類型：flac<br/>night、animals、night-time、chirp<br/>晚、動物、夜間、嘰嘰喳喳<br/>資料來源：freesound ( https://freesound.org )
