Sound library of the Western Rock Nuthatch

In this project, we are creating high-quality sound libraries to facilitate the subsequent development of an automated sound recognizer for the Western Rock Nuthatch Sitta neumayer.

Rock Nuthatch song variability

This is an investigation of the understudied song inventory of the Western Rock Nuthatch, Sitta neumayer, to identify song types and song structures of a nuthatch population in Greece. The aim of this study is to document the vocal variability of the Western Rock Nuthatch and discuss its ecological context.
