The Mount Kinabalu friendly warbler is also known as the friendly bush warbler (Bradypterus accentor).
This is one of the animals, plants, and fungi which the Heart of Borneo expedition will probably see this September. But maybe they will discover species, new to science. And they may find out how the unique species of Mount Kinabalu and the mountains around it evolved.
What are people packing for that expedition? See here.
