摘要
Supported by BP Conservation Programme, we mounted 40 nest for Strix davidi in suitable habitat at Lianhuashan Natural Reserve, Gansu in 2002-2003. Those nest boxes enable us close observing of breeding success of this rare species in 2005 for the very first time. The first pair bred laid 2 eggs in a nest box and both young were fledged. In May 2006, we monitored 3 territorial males in an area around 500 hm2 by playback method. In mid-June, we found droppings and pellets at the side of a vertical precipice, with hint that an active breeding site there. Two young owls were detected in the crown of a tall spruce tree, situated directly at the base the precipice, on which was thought to be their nest site.
