研究了甘贝尔白冠麻雀的歌唱变化，这些麻雀在马尼托巴省丘吉尔附近的苔原和北方森林栖息地繁殖。L的歌唱特征在不同栖息地之间没有显著差异。丘吉尔鸟的歌声具有与阿拉斯加种群相同的元素序列(即哨声、颤音、嗡嗡声和颤音)，但元素形式有所不同。白冠麻雀迁徙种群中没有方言支持距离假说的预测。
Song variation was studied in Gambel's White-crowned Sparrows (Zonotrichia leucophrys gambelii), breeding in tundra and boreal forest habitats near Churchill, Manitoba. No significant differences were found among habitats in song characteristics of Z. l. gambelii. Songs of Churchill birds had the same sequence of elements (i.e., whistle, warble, buzz, and trill) as Alaskan populations, with some variations in element form. The absence of dialects in migratory populations of White-crowned Sparrows supports predictions of the Ranging Hypothesis.
