Songbirds and humans share some common speech patterns
For both songbirds and humans, the longer the phrase the shorter the sounds
If you listen to songbirds, you will recognize repeated melodies or phrases. Each phrase is made up of distinct sounds, strung together. A study from researchers at McGill University has found that the song phrases of many songbird species follow patterns that are similar to those used in human speech. At least in some respects.
The songbirds the researchers studied, like humans---no matter what language they speak---tend to use shorter elements (whether these are words or sounds) when they are putting together longer phrases. Linguists speculate that this pattern, known as Menzerath's Law, may make communication more efficient by making things easier to understand or say.
But the McGill team suggest that, at least in songbirds, physical factors such as muscle fatigue and limited lung capacities may also play a role. They also speculate that similar factors could contribute to seeing Menzerath's Law in humans.
Do physical elements play a role in songbird (and human) vocal patterns?
"Although we see Menzerath's Law in all the songbird species we looked at, and others have seen it among primates and penguins, we aren't sure this necessarily reflects enhanced communication efficiency in non-human animals," said END
