The Regent honeyeater was once found frequently throughout southeastern Australia, but today it is on the brink of extinction. So far, only 300 individuals are thought to remain in existence worldwide. They are also known for their complexity in mating “songs”, but as their numbers begin to dwindle, ornithologists begin to notice this complexity diminishing, to the point where males not even singing like they did before. Today, there is a lot of evidence that the Regent honeyeater birds have forgotten how to sing, which could make the whole species extinct.

At times, Australian ornithologists found that the male Regent honeyeaters were mimicking the singing of other birds, such as the mink and the cuckooshrikes, but they did not give any explanation as to why that would be. happening. Some experts believe that imitation is seen as a deliberate strategy to avoid being attacked by larger birds. However, a recent study found the opposite.

“These poor birds don’t have a chance to learn what they should sing,” said Dr. Ross Crates, ecologist at Fenner Environmental Environment and author of the study. Save with other birds of the same species and learn from their songs “.

Juvenile Regent honeyeaters often learn to sing from adult members of their species, just as humans learn to speak, but because their numbers are too small, the resurrection space is too large, many. Young drums cannot hear the singing of the adults, so they begin to use and learn from the singing of other birds. And the problem is that those singing are not something that can attract hens, so their chances of finding a mate are slim.

Furthermore this species also has some extremely strange properties, when the young birds begin to hatch, the fathers and mothers usually tend to be very quiet, this is to avoid the attention of predators. bait. So the chicks will begin to learn their own song when they leave the nest, by listening to the adult birds singing and imitating them. But because their numbers are very small, they cannot hear other birds of their own kind in the wild.

“They are very rare and their territory is as large as 10 times the size of the UK, so finding individuals of the same species in a small area seems like a search,” said Dr. Crates. needles in the bottom of the tank and now they are forced to follow the singing of other birds.
