【摘要】 本文提供了西藏拉萨高山灌丛(海拔4000-4700m)和高山草甸荒漠环境(海拔4300-4700m)20种鸟类的繁殖生物学信息。这些物种中,3个是青藏高原特有的,17个则有广泛的海拔分布。所有这些繁殖资料是关于高海拔地区、特别是鸟种的繁殖海拔上限的首次报道。其中,几个物种的信息以前从未有过描述。本项研究可以增加我们的极端严酷环境下鸟类自然历史的知识。更多还原

【Abstract】 This paper provides the information on nesting biology of 20 bird species in alpine shrub (4000-4700 m a.s.l.) or alpine meadow-wasteland habitats (4300-4700 m a.s.l.) in Lhasa region,Tibet.Of these species,three are endemic to the Tibetan plateau and 17 widespread in altitudes.The data on these taxa are all new to the high-altitude environments,especially the upper limit of their breeding distribution.A few species are firstly reported with respect to nesting information in the world.The study will contribute our knowledge for natural history of birds occurring in the harsh,extreme habitats.更多还原
