四年来在草河口试验林场共采集523号鸟类标本,连观察所得,合计84种,分属于12目29科。其中在落叶松人工林(本区森林生境中最主要的类型之一)中棲息或繁殖的常见种类有33种。野外现察证明,有留鸟24种,旅鸟30种,夏候鸟26种,冬侯鸟2种。星鸦为偶然迁来的种类。对采集或观察到的鸟类以遇见频数和数量初步作了数量标志。食性分析证明,大山雀等35种鸟类为本区最重要的食虫鸟类;树麻雀,黄胸鹀等5种为对农林业相对有害的种类;环颈雉等13种可供狩猎。用木板巢箱在落叶松人工林内已经招到了红角鴞、大山雀、沼泽山雀、台眉鶲等4种食虫鸟类,为今后招引益鸟消灭森林害虫提供了部分依据。
In the past four years, a total of 523 bird specimens were collected from Caoweikou Experimental Farm, and the results were observed. Total 84 species belong to 12 orders and 29 families. Of these, 33 are the common species that habitat or reproduce in larch plantations (one of the most important types of forest habitat in the area). Proved outside the field, there are 24 kinds of resident birds, 30 kinds of travelers, 26 kinds of summer migratory birds, winter birdhouses 2 species. Star crows for the kind of accidental move. The number of birds collected or observed was initially quantified in terms of frequency and number of encounters. Feeding analysis shows that 35 species of birds, such as big tits, are the most important insectivorous birds in this area; 5 species such as tree sparrows and yellow chestnuts are relatively harmful to agriculture and forestry; 13 species of ring-necked pheasants are available for hunting. Wood nest box in the larch plantation has been recruited into the red angle grub, big tits, marsh tits, taiwanensis and other four insectivorous birds, for the future to attract beneficial birds to provide some evidence of the elimination of forest pests.
