鸟类形态指标是遗传与环境要素综合作用的结果,对于鸟类分类学和生态学具有十分重要的意义.研究选取人工救助的小天鹅和洞庭湖不同越冬期的小天鹅进行形态指标测定,首次对生活在洞庭湖的小天鹅形态指标进行了报道,并进一步比较了饲养条件下小天鹅形态指标与野外条件下小天鹅形态指标.通过比较洞庭湖不同时期越冬小天鹅形态指标,显示迁走前期小天鹅体重大于稳定期小天鹅体重,以便为长距离迁徙储备能量.研究讨论了小天鹅古北亚种和新北亚种形态指标,认为二者翼长、爪长、跗蹠、喙长、体重等形态指标不存在明显差异.对小天鹅形态指标的测定为小天鹅理论研究和保护提供了基础资料,对小天鹅生物学研究...

Morphological characters are determined by genetic and environmental factors and are important for taxonomy and ecology. Captive and wild tundra swan （Cygnus columbianus）were sampled and their morphological characters were mensurated in the study. This is the first report of the morphological characters of tundra swan from Dongting Lake. Morphological characters were compared between captive and wild swans. Body weights of swans before migration were heavier than during other periods. Storing energy for migration could explain this morphometr...
