The blue-collared parrot (Geoffroyus simplex) also known as simple parrot, lilac-collared song parrot, or lilac-collared Geoffroy's parrot, is a parrot found in the higher elevations of New Guinea. It is found from 500 to 2300m, mainly between 800 and 1900m (though food shortages will send them lower). It is 23–25cm, mainly green with a black beak, yellow wing bend, blue underwing coverts, and a pale yellow iris. Adult males have a blue collar across upper breast to lower neck above the mantle, adult females have some blue on the rear crown. Juveniles have no blue and a paler bill. There are two subspecies:

• G. s. simplex: On Vogelkop. 23cm

• G. s. buergersi: On rest of island. 25cm, collar on males is duller but wider in back.

It inhabits humid hill forest and forest edges. Flocks are up to 200.
