There are colour variations among many adult birds, viz. : The 

 bronzy-green lustre on both sides of body very distinct in some ex- 

 amples, but indistinct in others, which are probably tne older birds. 

 The lustre is probably duller in the female than in the male. The 

 length of wing is in average shorter in this than in the typical form; 

 it measures 116,5 — 129.5mm. instead of 121. 5 — 134.5mm. as in the 

 latter. Iris pale yellow, with a narrow outer ring of deeper colour ; 

 bill black ; foot black ; clour black. 



Immature. — Upper parts of body deep brownish ashy colour, 

 the edge of feathers faintly tinged with lustrous bronzy-green ; fea- 

 thers on forehead, crown, occiput, hind neck and sides of ne . with 

 dark shaft streaks ; edge of feathers on rump and upper tail-coverts 

 pale ; quills of wing and tail blackish-brown or dark brown ; outer 

 edge of the outer web of flight-feathers pale colour ; lower parts of 

 body pale yellowish with distinct brownish abhy shaft streaks which 

 are broadest on chest and much narrower on abdomen, where the 

 pale yellowish colour predominates ; under wing-coverts dull ashy ; 

 flanks and under tail-coverts with dark shaft streaks, round spots 

 and pale yellowish lace. 



Young. — Very similar to the young of the typical form, but the 

 edge of feathers somewhat more strongly tinged with bronzy-green. 



Irides is immature and young examples of the form are of a 

 pale lemon-green, alizarin-green, deep cobalt-green, etc. They ac- 

 quire the colour of the irides of adult birds with change of the imma- 

 ture dress into that of the adult.
