New distribution areas of the Sichuan wood owl (Strix davidi) were recorded at Lianhuashan Natural Reserve (Kangle county),Zecha (Luqu county) and Kache (Zhuoni county) in Gansu,China.Now its distribution includes west Sichuan,southeastern Qinghai and southern Gansu.Combined with the Ural Owl (Strix uralensis),this distribution range corresponds to the distribution of the genera Bonasa (B.sewerzowi and B.bonasia) and Perisoreus (P.internigrans and P.infaustus).All are related to the endemic birds in Qinghai-Tibet Plateau.Based on our work during 1995～1999,we reported our field observations and preliminary habitat characters of the bird.The main habitat of Sichuan wood owl in Gansu was found in the conifer and conifer-deciduous mixing forest from 2 900 m to 3 300 m.At the Lianhuashan Natural Reserve,the birds were observed many times,with some breeding activities.The population of Sichuan wood owl at Lianhuashan Mountains was an isolated one,and the reserve only protected about 3 360 hm+2.of its habitat.
