中文摘要 | 為了探討室內紫嘯鶇(Myiophoneus insularis )個體間的關係和棲息行為,吾人自民國74年8月至75年4月間在鳥類研究室觀察5隻紫嘯鶇的行為。個體之社會地位則由其攻擊、打鬥和逃避等3種行為判定。初步結果顯示:位序高者攻擊頻率較多,逃避頻率較少,位序低者則反之,地位相近之個體則出現打鬥的頻率較高。此外,位序高者傾向於攻擊地位與其較近者;相對地,對位序低者之攻擊則較少。又體重佔優勢之個體一般社會地位較高,而地位改變也會使體重發生變化。性別可能和社會地位有關,然由於外表上不易區分,尚待進一步研克。紫嘯鶇之棲息行為和社會地位有關,位序高者上至棲木的時間較早且棲息的位置也較高,此種情形或可能與鶇科鳥類之逃避天敵有關。 |
英文摘要 | From Aug. 1985 to Apr. 1986 5 birds of Formosan Whistling Thr-ush (Myiophoneus insularis) were kept in an aviary to study their soc-ial status and roosting behavior. Social rank was determined by the fre-quency, of assault, fight, and withdrawal behavior among different indivi-duals. The preliminary result showed that assaults were mostly given by higher ranked birds, while most withdrawal occured in the lower ranked birds. In addition, birds with approximately equal status fought most frequen tly. Higher ranked birds tended to assault birds with middle rank more frequently than those with lower rank. There was a positive relationship between body weight and social hier-archy. The dominant birds have heavier body weight than have subordinate birds, and the change of hierarchy among individuals also affected their body weight. Sex may also play an important role on the determination of social status. However, no sex dimorphism could be found in this spe-cies, and further study is needed. The roosting behavior of this species was affected by the social hier-archy of birds. The dominant birds roosted earlier and perched on higher branch than did subordinate birds. Such difference could be partly expl-ained by the predator escape tendency among this species. |
