摘要翻译：
许多鸟类的鸣叫，就像人类的言语一样，形成了鲜明的地域方言。我们认为方言的形成过程类似于磁畴形成的物理过程。我们以普吉特湾白冠麻雀的沿海繁殖地为例。先前的野外研究表明，该物种的鸟类在生命早期就会学会多种歌曲，当第一次建立领地时，会保留其中一种方言，以便与大多数邻居相匹配。我们引入了一个简单的格模型来描述这个过程，表明只要成鸟的死亡率足够低，这种匹配行为就可以产生单个方言域。将磁性材料中的死亡率与热力学温度联系起来，并与伊辛模型进行类比，计算出磁性材料的临界死亡率。利用与这些鸟类已知行为相一致的参数，我们表明沿海方言域形状可以通过将它们视为低温“条纹状态”来解释。

英文摘要：
  The songs and calls of many bird species, like human speech, form distinct regional dialects. We suggest that the process of dialect formation is analogous to the physical process of magnetic domain formation. We take the coastal breeding grounds of the Puget Sound white crowned sparrow as an example. Previous field studies suggest that birds of this species learn multiple songs early in life, and when establishing a territory for the first time, retain one of these dialects in order to match the majority of their neighbours. We introduce a simple lattice model of the process, showing that this matching behaviour can produce single dialect domains provided the death rate of adult birds is sufficiently low. We relate death rate to thermodynamic temperature in magnetic materials, and calculate the critical death rate by analogy with the Ising model. Using parameters consistent with the known behavior of these birds we show that coastal dialect domain shapes may be explained by viewing them as low temperature "stripe states".
