Birds Sang in Australia First

The first singing birds originated in Australia - science.

Singing birds originated in Australia. This is true. Just when they moved to other parts of the world is not yet clearly known. Evidence from DNA sequencing and fossils point to this happening approximately 23 million years ago.

They first "hopped" from island to island until they reached Indonesia. From there it was easy for them to spread to Asia. The progression to populate the world occurred rapidly, like when humans moved out of Africa.  It took only a few thousand years for the initial "breakout".

Birds of song could not leave Australia before 23 million years ago as Indonesia before that time was a small island and there was a huge distance of ocean for the birds to cross to reach other land masses.

Half of all bird species are song birds. The only continent where they did not go is Antarctica. This is a mystery because penguins are birds, so the cold barrier is not significant for birds.  Many native song birds died out in Australia due to the climate making the continent arid.
