A recent study published in the journal Proceedings of the Royal Association B revealed that the regent honey bee forgot its song. Cheerful birds, once abundant in the Southeast Australia, is losing its song because of the threat of extinction it faces. There are currently only 300 of this species globally. Due to the scarcity of birds, their offspring cannot learn and sing their natural melodies.

Ross Crates, a study author and member of the Troubled Bird Research Group at the Australian National University, says that birds forget their language when they cannot gather near others of their age. species.
“They don’t get a chance to hang out with other honey eaters and learn what kind of sounds they have to make,” Crates explains.
Discovered by accident. In their research, the authors simply looked for regent queen bees as they became serious. have ability to be extinct.
“They are so rare and the area they can occupy is so large – maybe 10 times the size of the UK – we are looking for a needle in the bottom of the tank,” explains Crates.
During the research, they noticed bird sing unusual songs. About 12% of the regency butterfly’s population forgot to sing its original melody, the team said.
Crates explains that young birds need to combine with other nectar-eating birds to learn to sing their particular song. If they cannot find other birds to interact with, they will not be able to transfer their voices to their memory.
“As baby birds, when they leave their nests and go out into the open world, they need to combine with other older males so they can hear them sing and repeat the song over time,” Crates said. “But if those male birds sing a strange song, the females may not mate with them. So we hope that if they hear what they should sing, they will learn to sing on their own. ”
On the other hand, the researchers shared that they had begun training captive regent honey bees using their natural song recordings. They plan to release the wildly trained birds in the hope of restoring their population and its song.
