We conducted the study by radio telemetry and roadside count. The radio telemetry was conducted from July 2008 to March 2009 and July to August 2009, while the roadside survey was conducted from March 2009 to August 2009. The average home range size of tawny owls at Tataka was 155.14 ± 94.74 ha (n=5) by the Minimize Convex Polygon method, The home range of one bird radio-tracked for the entire year varied seasonally largest in summer and smallest in spring (n=1). With the respect of habitat selection, owls preferred to select the roadside habitat, but the selection for the habitats of mature forest, artificial forest, bared rocky area, and stream varied. The use of the roadside habitat by the owl was not remarkably affected by lunar cycle neither by radio telemetry nor by roadside survey data; but the roadside use had remarkably changed by month with roadside count(F=8.499, p<0.001).The species used roadside less often in March, and then increased its usage since then. Owls appeared at roadside without difference in terms of the time of night by radio telemetry(K=5.528, p=0.63), but not for road count, with lower occurrence after midnight(K=7.343, p<0.05). Owls preferred to perch on the road signs more frequently than expected, as compared with that on the tree branch. Dr. Yuan-Hsun Sun 孫元勳 博士 2010 學位論文 ; thesis 56 zh-TW
