摘要

摘要莱索托有家雀、角麻雀和灰头麻雀三种传道者。家麻雀是一种引进物种,1954年在莱索托首次被记录。今天,这三种物种在全国所有生态区的城市和农村地区都非常多(作为优势或次优势)。随着海拔的增加,角雀相对于其他麻雀种类的比例增加,而灰头麻雀则相反。家雀的比例似乎只受海拔的轻微影响。在某些地区,家麻雀可能会取代灰头麻雀。

The Status Of Sparrows In Lesotho, Southern Africa
Abstract There are three Passer species in Lesotho: House Sparrow P. domesticus, Cape Sparrow P. melanurus, and Grey-headed Sparrow P. diffusus. The House Sparrow is an introduced species, recorded first in Lesotho in 1954. Today, all three species are very numerous (as dominants or subdominants) in urban and rural areas in all ecozones in the country. With an increase of altitude the proportion of Cape Sparrows in relation to the other sparrow species increases, while the reverse is true for the Grey-headed Sparrow. The proportion of House Sparrows appears to be only slightly affected by altitude. In some areas, the House Sparrow may displace the Grey-headed Sparrow.
