Ravens - Intelligent Rascals of the Skies | Free Wildlife Documentary Hardly any other species of bird has preoccupied mankind quite as much as corvids. They are exceptionally curious, teachable and intelligent birds. Ravens are the only birds that not only use tools, but also make them themselves. Many live in close, social structures and remain with one partner throughout their lives. This HD production presents many new and fascinating insights into the world of corvids: Alpine choughs in the winter world of the high mountains, rook colonies in towns, or the small, intelligent jackdaw, jays, hooded crows and of course, the king of the corvids, the northern raven. The raven is not just the world's largest songbird, but increasingly continues to surprise science due to its extraordinary intelligence. ▬▬▬▬▬▬▬▬▬ Subscribe Free Documentary - Nature Channel for free: https://www.youtube.com/channel/UCQtW2oz8ec8pHjjxawujNjg?sub_confirmation=1 Facebook: https://www.facebook.com/unsupportedbrowser Twitter: https://bit.ly/2QlwRiI ▬▬▬▬▬▬▬▬▬ ▬▬▬▬▬▬▬▬▬ Free Documentary is dedicated to bring high-class documentaries to you on youtube for free.
