True.
It has been studied in a research study that claims birds have the ability and capability to regenerate their hair cells. This regeneration happens when the hair cells die but come back to its original form despite the damage it might have faced. Further, they can also regrow their hair cells in their ears.
I believe it is behavioural isolation. When there are changes within a certain species, e.g. new birdcalls are formed in certain individuals in a species, "traditional" birds may not like such mating calls and only choose to mate with the more common birdcalls from majority of the birds. There are also some birds that may like the new birdcalls, and choose to mate with birds with those birdcalls. They become genetically isolated as they continue such behavior. Eventually, through genetic drift and other mutations, different species form from a single specie.
Hope this helps! :)
