Congratulations to Cologne Zoo, Germany, for their significant involvement in the Silent Forest Campaign!
This time, it is via colorful articles in the Kölner Zoo Magazin (edition Summer 2018) that they raise awareness of Southeast Asian Songbirds status but also of their European counterparts situation. They especially talk about the Bird of the year 2018: the Common starling (Sturnus vulgaris).
German speakers, you can read the complete magazine here.
Also have a look at page 11, listing all the Bird-related events happening in Cologne Zoo in 2018!
