研究了1999年强台风（9918 Bart）对日本南部暖温带森林鸟类群落的影响。总体丰度和物种数量在正常年份表现出明显的季节性，冬季丰度和数量较高，主要是由于冬季候鸟的大量涌入。饮食和觅食行会的组成也随着季节的变化而变化。食果/花岗动物和杂食动物在冬季增加，食虫动物在冬季减少。在觅食行会中，森林内部或边缘依赖的种类在冬季增加，而一般依赖的种类保持不变。因此，我研究了台风9918 Bart在冬季和夏季的影响，比较了其通过前三年和经过后两年的数据集。在台风后的第一个冬季，鸟类丰度显著低于三个对照年，但在第二个冬季恢复到与对照年相同的水平。在台风过后的第一个夏季和第二个夏季，鸟类丰度均显著高于对照年。台风对饮食和觅食行业的影响也有所不同。冬季优势食果/花石动物在第一个冬季较少，导致该季节鸟类总丰度下降，而杂食动物和食虫动物的增加导致夏季鸟类总丰度增加。森林内部依赖物种的减少导致冬季总丰度的降低，森林边缘依赖物种的增加可能导致冬季和夏季总鸟类丰度的增加。这些不同的反应在不同的觅食和饮食行会共同影响鸟类的总丰度。干扰事件（台风）对冬季和夏季鸟类总丰度的影响相反。
ABSTRACT The effects of a severe typhoon (9918 Bart) on a bird community in a warm temperate forest, southern Japan, in 1999, were investigated. The total abundance and number of species showed clear seasonality in normal years, and were higher during winter mostly due to the influx of winter visitor species. The composition of dietary and foraging guilds also changed among seasons. Among the dietary guilds, frugivores/granivores and omnivores increased in winter, whereas insectivores decreased in winter. As for the foraging guilds, forest interior- or edge-dependent species increased in winter, whereas generalists remained constant. Therefore, I examined the effects of typhoon 9918 Bart in winter and in summer, comparing the data sets from three years before and two years after its passage. In the first winter after the typhoon, the abundance of birds was significantly lower than in all three control years, however it recovered to the same level as the control years in the second winter. In contrast, in both the first and second summer after the typhoon, bird abundance was significantly higher than in the control years. The effects of the typhoon also differed among the dietary and foraging guilds. The winter dominant frugivores/granivores were fewer in the first winter leading to a decrease in total bird abundance in that season, whereas the increase in omnivores and insectivores resulted in the increased total bird abundance in summer. The reduction in forest interior-dependent species led to the lower total abundance in winter, and the increase in forest edge-dependent species may have led to the increase in total bird abundance both in winter and in summer. These different responses among different foraging and dietary guilds affected total bird abundance in concert. The disturbance event (typhoon) appeared to cause opposing effects on total bird abundance in winter and in summer.
