[edit] Identification

38-48 cm
Green upperparts, green or rufous underparts depending on subspecies (very variable how dark), black central spot on upper breast, black central crown surrounded by blue band, black eyemask sometimes edged pale at the back.

Tail is green with blue lower tail with two longest feathers showing an area missing barbs followed by an area with barbs (rackets); the tip of these feathers is black in some subspecies.

Notice that the tail feathers are normal when growing, the barbs fall off shortly after, and it is therefore possible to see a bird of this species that is missing rackets (feathers may also break below the rackets).
