Urban pigeon during sampling

In the context of a research project, we are investigating the prevalence of two avian pathogens in pigeons in various Swiss cities. For our study, swab samples are taken from pigeons in urban pigeon lofts and then examined in the laboratory. For the pigeons, it might feel a bit like the Corona test we got used to during the pandemic. The photo shows a pigeon looking somewhat dismayed at the camera while being sampled. It was taken in the pigeon loft of the "Tierpark Bern".
