This is juvenile marquesan fly-catcher, the first one I ever manage to see on Mohotani Island (uninhabited island). There is only 1 population in the world, on Mohotani. When the bird is less than 3 years old, it is cinammon coloured. If it a male, after 3 years, the feathers will turn entirely black. If it is a female, the back and the wings will turn black, while the stomach/chest becomes white. This is the only fly-catcher in French Polynesia that has a colour difference between the females and the males (the other 3 species also change colour from orange-cinammon colour to dark feathers after 3 years).
