The Rackelhahn is quite an odd hybrid. Some feel it was formed to see what the result could be when two large game birds came together. The Western Capercaillie is actually the largest in the grouse family while the Black Grouse, also a large grouse in its own right, does not really have any distinct qualities. Some feel the Rackelhahn was created as an answer to what could happen if the Black Grouse were to go extinct.

The Western Capercaillie experiences the same issues, which could be why scientists joined the two. If they could create a solid species, it could be formed in a lab without any potential extinction problems. However, the Rackelhahn is completely sterile. This could change with gene editing, which would allow a possible future for the species in the wild.
