Correction to: Journal of Ornithology https://doi.org/10.1007/s10336-021-01879-9

In the original publication of the article, "Availability of data and materials" section was published with an error.


It is given as "Sound recordings used to generate spectrograms (Fig. 1, Fig. 2, Online resource 1) are provided at https://doi.org/10.7479/b478-jj11" but it should be "All experimental recordings used in the analysis have been deposited in the Animal Sound Archive at the Museum for Natural History in Berlin and are available under the CC-BY-SA Licence at the following https://doi.org/10.7479/b478-jj11".


The original article has been updated.
