Grasping complexity in bird songs

Justn Kitzes, an assistant professor in Pitt’s Biological Sciences Department, works with Pitt CRC research consultant Barry Moore II in refining OpenSoundscape – a machine learning program Kitzes developed to create dense, meaningful and applicable data on the distribution and survival of species based on a model of simple acoustic sensors acquiring vast sets of bird calls and machine learning programs making sense of the data.

“Bird calls have lots of variability between them, but also lots of similarity," Kitzes explains. "Bird calls can vary greatly within one species. Birds sing simultaneously on top of each other. It is a complex picture.” Here, Moore, left, and Kitzes show off one of the acoustic sensors.
