New discovery: Birds also know how to

Research by scientists at Oregon Health University shows that birds' voices are also altered after drinking.

We all know that after drinking alcohol, our voices will become more lethargic. This means that alcohol will make our voices change.

Many people wonder if the birds have changed their voices by alcohol. Recent research by scientist Christopher Olson and colleagues at the Oregon Health University has shown that birds (especially sparrow) are also "stalking" when drunk.

To come to this conclusion, experts mixed a little juice with 6% alcohol and poured it into two jars - placed in the birdcage early in the morning.

Researcher Christopher Olson said: "At first, we thought these finches would drink because they would be shy when they discovered something strange. But we were wrong, these finches are completely ready and happy to enjoy those water bottles ".

After enjoying the wine, the birds were taken out to check their alcohol content. With the measured alcohol level of 0.05 - 0.08%, the song of the birds began to change. No longer a high-pitched voice, the sound of sparrow began to grow deeper.

For a long time, sparrows have been used by scientists to study human vocal learning or how people can communicate with each other in language.

Olson said: "Obviously, alcohol causes the birds to change their songs. In the future, we want to understand more about the effect of this substance on behavior. of birds ".
