Declarations

:

: Under current animal experimentation legislation in the countries involved in our study, no ethical clearance is required for purely observational research. In our case, the animals are observed without modification of their daily routine, without any attempt to engage with them, and without restriction of their movement. Furthermore, as the humans, who all took part in the study voluntarily with an informed consent obtained from all subjects, were only filmed from behind so that they cannot be identified and as no data was collected on them, our work does not fall under the European Union General Data Protection regulation for human rights to privacy.
