Young. The young males strongly resemble the females for the first

 the bill appears, composed of black and white feathers, 

 and the head and neck acquire the glossy green colour. 

 The back also becomes darker, and there are indications 

 of the exterior black and white scapulars, After the 

 third moult the bird is matured.
