Since 2015, Katarzyna has been singing to bonobo great apes, and recording their reactions. She has sung to bonobos at San Diego Zoo and at Wilhelma Zoo in Stuttgart. She is also a frequent fundraiser, promoter and endorser of both the Lola Ya Bonobo Sanctuary in the Democratic Republic of Congo and the Bonobo Conservation Initiative.
Here is a short clip of her singing to bonobos in Germany:
