Appel à participation à une étude sur la façon dont la covid-19 a changé l’observation des oiseaux :

« Dear birders,
Hope you all are fine; we are doing a short study how COVID-19 has changed birding. Please help us and answer a few questions, that take some minutes. You can also forward the link to others.

The study is in several languages and we would be happy for your participation. The study is hosted by the University of Tübingen, and run by a team of people, also being birders.
Stay healthy and good birding,
Christoph Randler (Tuebingen, DE), Jukka Jokimäki (Arctic Centre, Univ.of Lapland, Rovaniemi, FIN) & Piotr Tryjanowski (University of Life Sciences, Poznan, PL) and Maria de Salvo (Univ Catania, IT).
