This pretty species is common in Mexico. I hav^e killed

The only difference between this species and the preceding 

 one, consists in the colour of the underside, which is metallic 

 emerald-green on the throat and breast, and the colour of its 

 rectrices which are steel-blue with a narrow bronze tip on 

 central feathers, the tail is also shorter.
