Experiments on the corn bunting were carried out in two localities of different dialects. In the center of the territory of each bird, we played two natural songs: either one local song and one song of the foreign dialect or two local songs coming from a neighbor and from a non-neighboring individual. The following results were obtained: (1) The behavioral responses are always more intense to the local song than to the song of a foreign dialect. Thus, the behavior of the corn bunting is similar to that of species with dialects studied up to now. (2) Eighty percent of the birds tested with the song of the foreign dialect react weakly or not at all. This peculiarity, which is specific to the corn bunting, suggests limited possibilities of generalization in this species. (3) The behavioral responses to the songs of a neighbor and of a non-neighboring individual of the same locality, are aggressive and of the same intensity. This means that the song of a neighbor, emitted from a different place than usual, is perceived by the bird as a threat to its territory.
对黍鹀的实验在两个使用不同方言的地区进行。在每只鸟的领地中心，我们播放两首自然歌曲：要么是一首本地歌曲和一首外地歌曲，要么是两首分别来自邻居和非邻居个体的本地歌曲。得到了以下结果：(1) 对本地歌曲的行为反应总是比对外地歌曲的反应更强烈。因此，黍鹀的行为与迄今研究过的有方言的物种相似。(2) 用外地歌曲测试的鸟中，80% 的反应微弱或根本没有反应。这种黍鹀特有的特性表明该物种的泛化能力有限。(3) 对同一地区邻居和非邻居个体歌曲的行为反应具有攻击性且强度相同。这意味着从与平常不同的地方发出的邻居的歌声被鸟视为对其领地的威胁。
