Dear MEL Topic Readers,
Birds aren’t all singing the same song. They have dialects, too
Though humans say birds sing, birds, usually the male, communicate to scare their neighbors or to attract female partners. But are birds of the same species always sing the same song, or in the same way? Do they have different languages or dialects like humans?
For some bird species, singing is innate, meaning they sing in the same way in any place. But others seem to learn to sing from their adult males in the environment so that they sing differently from the ones of other territories. It sounds like having local dialects like humans. If such birds are isolated from their peers, they don’t learn to sing their songs at all and keep babbling like a baby. Interestingly, when they learn to sing from their adults, they often make changes or mistakes. And those altered songs are passed through generations in the territory and eventually become a local dialect.
We humans just enjoy the way birds are singing but they sing for their purpose in their own way.
Enjoy reading the article, listening to their songs, and seeing the sonograms to learn why and how birds learn to sing.
