HUMMING-BIRD. 307 



M. Vieillot esteems the five last described as one and the same bird, 

 at different periods of age, and the Black-breasted as the complete, 

 and adult. To this we may assent, in all, except the Green- 

 throated, in which the tail, as it appears in the Pi. enl. is slightly 

 cuneiform ; but in all the others even at the end.
