The research on returning thefilial generation of semi-scatter-fed red-crowned crane to wild state
In view of the present situation that wild population quantity of migrating wild red-crowned crane is reducing yearly,Zhalong national nature reserve has made beneficial explorations on returning the bredred-crowned crane through artifitcial propagation to wild state by off site conversations(in the cranes domesticating and breeding centre).By the end of 2014,almost 200 red-crowned cranes were returned to wildstate.Semi-scatter-fedred-crowned crane population occupies the breeding region and ingestion zone earlier every year,probably which can shock the inhabitation and breeding of those wild one which reaches Zhalong wetland later.The time and place of returning red-crowned crane to wild state etc. can determine if returning red-crowned crane to wild state is successful directly.Change the suitable place of returning red-crowned crane to wild state from single one to multi-one,which can avoid the shock to wild red-crowned crane population.The time of releasing the bred red-crowned crane by artifitcial propagation is advanced from april to last october,which can enhance abilities on building nest,breeding independently and brooding of the bred red-crowned crane by artifitcial propagation after being released.
