自 19 世纪中叶引入北美和夏威夷群岛以来，北美和夏威夷群岛的麻雀 (Passer Domesticus) 在颜色和大小方面就出现了明显的适应性分化。北美的地理变异模式与本地多型物种所显示的模式相似，符合格洛格和伯格曼的生态地理规则。麻雀种群的种族分化可能需要不超过50年的时间。
Conspicuous adaptive differentiation in color and size has occurred in the house sparrow (Passer domesticus) in North America and the Hawaiian Islands since its introduction in the middle of the 19th century. Patterns of geographic variation in North America parallel those shown by native polytypic species, in conformity with Gloger''s and Bergmann''s ecogeographic rules. Racial differentiation of house sparrow populations may require no more than 50 years.
