Tail : Rectrices black, glossed with dark bronzy, green and deep purple. 

 The tail is deeply forked and the under tail-coverts, which are white, 

 exceed slightly in length the longest rectrices. These under tail-coverts 

 are so developed as to appear like true rectrices ; see Fig. 195.

Wings : White except the greater series of coverts, the scapulars, 

 bastard-wing, primary-coverts and quills, all of which are glossed with 

 bronzy green and deep purple. 



Lower parts : White, including the under tail-coverts, axillaries and 

 under wing-coverts. 



The sexes are alike in color. 



Young birds, when full grown, are much like adults. The under wing- 

 coverts are dusky, as are the marginal coverts. The bare skin about the 

 eye is not so highly colored and there are none of the warty papillae that 

 characterize this region in old birds. (Male P. U. O. C. 8820. Province
