由于跟随自由生活、分散的幼年鸣禽的困难，人们对这些幼鸟何时、何地、如何以及从谁那里学习歌声知之甚少。为了探索这些问题，我们研究了切麻雀（Spizella passerina），其中男性有一个单一的，简单的歌曲，但人口可能包含20-30种不同的歌曲。在马萨诸塞州西部的研究地点，我们用颜色标记了324只雏鸟和32只雏鸟。其中12只雄性回到了我们的研究区域，分散在离它们纳塔尔地几百米到1.8公里的地方。每只一岁麻雀的歌声与繁殖区上的一只近邻麻雀非常接近，这表明一只一岁麻雀在分散后会精确地模仿一只近邻麻雀。这项实地研究和以前的实验室研究的证据表明，一个年轻的男性能够学习歌曲无论是在他的孵化年或第二年的春天，也许取决于他的机会，歌曲曝光或社会互动与领土的邻居。
Given the difficulty of following free-living, dispersing juvenile songbirds, relatively little is known about when, where, how, and from whom these young birds learn their songs. To explore these issues, we studied the Chipping Sparrow (Spizella passerina), males of which have a single, simple song, but populations of which may contain 20-30 different songs. In our western Massachusetts study sites, we color-banded 324 nestling and 32 fledgling sparrows. Twelve of these banded males returned to our study areas, dispersing a few hundred meters to 1.8 km away from their natal territories. The song of each yearling closely matched only one of his immediate neighbors on the breeding territory, revealing that a yearling sparrow precisely imitates one of his close neighbors after dispersal. Evidence from this field study and a previous laboratory study show that a young male is able to learn songs either during his hatching year or the following spring, perhaps depending on his chances of song exposure or social interaction with territorial neighbors.
