einnotig slow high (5-7 KHz) .
Call:Wikipedia says 'The common kingfisher has no song.
The flight call is a short, sharp whistle chee repeated two or three times. Anxious birds emit a harsh, shrit-it-it and nestlings call for food with a churring noise.'
The NABU app only has calls,
which seems to confirm this. Therefore I'm classifying all recordings as calls,
even though some say Song at Xeno-Canto. [Link] Most heard is the thin and penetrating contact call: A short "tzee", or disyllabic "tzee-tzu", with a ringing metallic quality. In excitement it is often alternated with ringing trills "tzeerrrrrrrrrr". [Link]
