Video clip: Urmas Lett, Eenet
Translation: Liis
Video: 14. aprill 2012 The jays circled around the empty eagle nest for several hours, studying it from various angles. If it had been a single male bird it might have been seen as megalomania ... The buzzard started calling when the pretenders came too close.
At the end of the video a jay weighs down a large branch towards the buzzard in the nest. Can it be regarded as use of a tool?
