The Cretan mountains and gorges are refuges for the endangered lammergeier vulture. The eponymous mountains of the park are inhabited by the magnificent lammergeier, or bearded vulture. The Egyptian vulture ("Neophron percnopterus") and the lammergeier ("Gypaetus barbatus") are true carrion-eating vultures. Most magnificent of all is the lammergeier (bearded vulture) with a 3-metre wingspan. The lammergeier and the golden eagle are common raptors here. Taxonomic confusion may have resulted from the physical appearance of the lammergeier. Some authorities think this a good description of a lammergeier; others do not. The valley is named after the Lammergeier, which is called "Yol" in Mongolian. The "kyorebni" is called a "Lammergeier" in Terran Standard ("City of Sorcery", Chapter 11). The lammergeier is sparsely distributed across a vast, considerable range. Birdwatching is also common, with the lammergeier and golden eagle especially sought for.
