The Tibetan antelope shows a unique migration strategy among the ungulates of the Tibetan Plateau. They are partially migratory: Some populations make longdistance migrations moving 300-400 km annually, while others remain resident year-round. Only the females migrate within the migratory populations, while most males remain on their collective winter range year-round. Tibetan antelope migration is synchronized with their reproduction cycle. Around midMay, multiple populations from different wintering grounds depart to a shared summer range for breeding and return with their newborns in July and August. The Hoh Xil population spends the winter in the Sanjiangyuan National Park and then the females migrate to the shared summer breeding range in the Hoh Xil (or Kekexili) UNESCO World Heritage Site.
