The Czech Republic probably does not have a more endangered species than the black grouse. The country hosts many birds which also face great problems and whose numbers are considerably lower than those of the black grouse, e.g. the little owl (Athene noctua) and the saker falcon (Falco cherrug). These have, however, a significant advantage as for survival: they manage to fly dozens or hundreds of kilometres and thus have at least a chance of finding suitable nesting grounds or new partners elsewhere, and mainly… they are within flying distance of their relatives in neighbouring countries.
