男性白喉麻雀暴露于播放录制的歌曲的反应不太强烈，邻居的比一个陌生人的歌曲时，扬声器位于附近的领土边界相邻的邻居的问题或在领土的中心。然而，当一个邻居的歌是从领土的边界最远的邻居的通常位置，但另一个邻居住的地方，反应一样强烈，一个陌生人的歌。这证明了个体通过歌曲和位置对邻居的识别。根据在上述区域中心获得的结果，可以认为，通过歌曲进行识别与位置无关。对陌生人歌曲的反应在领地中心比边界附近更强。讨论了这种行为的一种近似机制和可能的功能。
Male white-throated sparrows exposed to playback of recorded songs responded less strongly to a neighbor's than to a stranger's song when the speaker was located near the territorial boundary adjacent to the neighbor in question or in the center of the territory. However, when a neighbor's song was played from the boundary of the territory farthest from that neighbor's usual location but where another neighbor lived, response was as strong as to a stranger's song. This demonstrates individual recognition of neighbors by both song and location. Based on results obtained in the center of the territory cited above, it is suggested that recognition by song is independent of location. Responses to strangers' songs were stronger in the center of the territory than near the boundaries. A proximate mechanism and possible functions of this behavior are discussed.
