This wonderful video of European crane courtship is currently copyrighted and not freely licensed. The video comes with a button that allows you to embed it in a website and its article has a button where you can order the video.
The video is on the website of Stichting Natuurbeelden and they made a nice offer; 50 of their videos will become available under the CC-by-sa license. There are many great videos to choose from and for all kinds of reasons, the initial offering is to choose at most 50 of them.
Organising this selection will not be easy and the relevance of some videos is very much in the context of nature in the Netherlands. European cranes are breeding again in the last few years. When the fifty videos are selected and when they are used in our projects, these videos will be seen quite often. At the moment when I write this, the number of views for this video is only 136.
