Thèse examples belong to the eastern smaller form, which has a much smaller bill. Both birds 

 are immature. The feathers of the throat and foreneck are not yet crinkled. They are distin- 

 guishable from M. ater (Lesson) only by the purplish gloss of back, wings and tail and by 

 the more bluish gloss of the head, which is green in ater.
