In the morning, Belarusian colleagues continued their search for aquatic warbler females, and in the evening they ringed the birds with special rings. More about them and the ringing process – in this video. Petras continues to manage the surroundings of aviaries. Today, the grass around them is mowed in order to better see the predators approaching the aviaries and to scare them (animals avoid mowed areas) after the birds will be moved in aviaries. We will talk about protection from predators more in other video stories.
