溪頭地區藪鳥行為的初步研究
The Preliminary Behavioural Study of the Steere's Babbler at Chitou Area
摘要
自民國75年3月至76年4月止，對溪頭地區藪鳥（Liocichia steerii）進行調查研究，藪鳥活動的地點常出現在兩種不同林相的交界帶，停留的植物77%是4公尺以下的灌叢和底層植被，而停留的位置則有85%（n=304）低於2公尺以下。每日作息時間大致符合中部地區民用曙光始及暮光終時刻。藪鳥是雜食性鳥類，取食的內容十分廣泛，從果實、無脊椎動物、昆蟲，一直到各式各樣的人造食物。在冬天自然界中的食物減少時，遊客遺棄的食物是藪鳥主要食物來源之一。藪鳥在極度饑餓的情況下，亦會啄食同伴的屍體。藪鳥的鳴叫聲大致可分為雄性領域性叫聲、雌性回答聲、兩種警戒聲、對峙打架聲、逃跑聲、危困的叫聲、個體間的叫聲和幼烏乞食的叫聲等九種，每種叫聲皆不相同，所代表的意義也不同。雌性問答聲和雄性領域性叫聲分別為雌雄個體特有的叫聲。在非生殖季節，藪鳥成群活動，而以全年最冷的一月份，聚合的數量最多。在聚合的群體內，每一個體間有位序（hierarchy）存在，並以直鏈式的高低位序排列。自曙光後一小時內，藪鳥即以二隻為最小單位聚合而成數量不等的群體活動，但距暮光終了二小時內，又回復成對的活動，在非繁殖季節，藪鳥配偶間的聯繁關係仍然存在。

The study was conducted from March 1986 to April 1987 at Chitou to learn the behaviour of the Steeres Babbler (Liocichla steerii). The bird was often found active in ecotone between two plant communities. Of all plants that bird stayed, 77% were bushes and ground covers under 4 meters. Of those sites (n=304) that bird perched, 85% were below 2 meters. The change of the daily active pattern of the species coincides with the change of daylight length through season.The species is omnivous. Its diet consists of fruit s, small invertebrates, insect s and man-made foods. In winter when food was scarce, food left by visitors provided one of the major food sources. Under the extreme condition, dead birds was observed eaten by their consorts.Calls from the species could be classified into 9 types male territorial call, female answering call, 2 types of alarm call, antagonistic fightening call, escaping call, distress call, individual communication call and chick begging call. Among them, female answering call and male territorial call are sex specific.The species forms flock in non-breeding season, though the pair bond is still maintained. The largest flock was found in Jaunary, the coldest month of the year. Within flock a linear relation of hierarchy could be found among individuals. The temporal change of flock size varied from time to time. Starting from 2 birds about one hour after dawn, the flock size increased and then reduced back to 2 birds about two hours before dusk.
