【摘要】 <正> 一、引 言 湖南省是国内重要林区之一。关于林区中所产鸟类,已往资料是很贫乏的。1900年,Ogilvie-Grant记述自湖南洞庭湖至云南西部所采到的鸟类,其中采自湖南境内的仅32种。直至1933年,任国荣刊载了湖南西南部鸟类114种,Davis等(1951)梁启燊(1956)对湘西和湘北的鸟类,亦均有所记述;但对于全省鸟类,则未曾做过调查。更多还原

【Abstract】 An avifaunal survey was conducted in Hunan province during 1955-57, especially in connection with the study of birds eating the pine-caterpillars (Dendrotimus punctatus). A total of 2874 specimens were collected. They are found to belong to 14 orders, 38 families and 180 species with 6 more subspecies.The avifauna of Hunan situated in the Mid-China Zone is very similar to that of the South China zone, both zones exhabiting characteristics of the Oriental Realm. There are certain Palaearctic elements found present especially in the northern part of the province. An analysis of avifaunal features shows differences among the different parts of the province with respect to dominant species and certain forms with more or less limited ranges of distribution.From an examination of stomachs’ contents, it has been shown that out of the birds collected, 73 species are the more common insect-eating forms. 18 species are found to be feeding on the eggs and larvae of Dendrolimus punctafus, and are, therefore, particularly beneficial to the coniferous forests, which cover most of the hilly lands of the province.Part I of the report deals with non-passerine birds. The number of species included in the various orders and families may be shown below:更多还原
