The study, which involved over 100 bird species, found that birds in different regions exhibit distinct nest-building styles. For example, in the UK, birds like the robin and the wren build their nests in a specific way, while in the other parts of the world, birds like the weaver bird and the bowerbird build their nests in a unique way. The researchers also found that these architectural styles are passed down through generations, suggesting that nest-building is a learned behavior.

* White-browed sparrow weavers and white-eared sparrow weavers are two distinct species of birds. * These species have different nest-building styles. * The study investigates the mechanisms behind these differences in nest-building styles.
