我们研究了非迁徙纳托尔白冠麻雀 Zonotrichia leucophrys nuttalli 的颜色标记种群在野外的鸣叫共享和鸣叫类型的传播。对父亲、他们的男性后代（儿子）以及招募地点儿子的邻居的歌曲进行了光谱分析，并进行了定性和定量比较。为了确定儿子的歌曲是否与他的父亲或定居点邻居的歌曲更接近，我们对每个父子-邻居三人组中歌曲的频率和时间特征进行了多元聚类分析。 16 个儿子中有 14 个的歌曲与邻居的歌曲而不是父亲的歌曲聚集在一起，这证实了邻居的歌曲匹配是青少年领土定居的一个组成部分。对方言区域内歌曲的频率和时间测量的主成分分析表明，歌曲分为邻域且非随机分布。多变量分析表明，儿子可能会吸收邻居歌曲的频率和时间特征，而无需匹配短语或复杂的音节。讨论了指导性学习与选择性学习模型的含义。敏感阶段的关闭时间、感觉阶段和可塑鸣叫阶段之间的无声间隔的长度以及鸣叫结晶的时间仍然是鸣叫个体发育中的悬而未决的问题。 (C) 1998 年动物行为研究协会。
We investigated song sharing and dispersion of song types in the wild in a colour-marked population of the non-migratory Nuttall's white-crowned sparrow, Zonotrichia leucophrys nuttalli. The songs of fathers, their male progeny (sons), and the neighbours of the sons at recruitment sites were analysed spectrographically and compared qualitatively and quantitatively. To determine whether a son's song more closely matched that of his father or a neighbour at the site settled, we subjected frequency and temporal characteristics of songs within each father-son-neighbour triad to multivariate cluster analysis. The songs of 14 of 16 sons clustered with their neighbours' rather than their fathers' songs, confirming that song matching of neighbours is an integral component of territory settlement by juveniles. Principal components analysis of frequency and temporal measurements of song within a dialectal area show that songs group into neighbourhoods and are non-randomly distributed. Multivariate analysis suggests that sons may entrain on frequency and temporal characteristics of a neighbour's song without matching phrases or complex syllables. Implications for models of instructive versus selective learning are discussed. The timing of closure of the sensitive phase, the length of the silent interval between the sensory phase and plastic song stage, and the time to song crystallization remain open questions in song ontogeny.
