Habitat. Southern Mexico. 



"This Humming-Bird/' says M. Montes de Oca, "is generally known by the name of Chupa-mirto comun de 

 pecho bianco, or Common White-breasted Myrtle-sucker. It is found very abundantly and at all seasons of the year 

 in the vicinity of Jalapa, Coatepec, Orizaba, and many other places in Mexico, where it remains all the year round, 

 and I have often found its nest in the months of April and May. 



"The nest of this species, like those of nearly all the Humming-Birds of this part of Mexico (Jalapa), is lined 

 with the tull silky floss, and is most ingeniously covered on the outside with moss from the rocks. The eo-o-s 

 are generally two in number, but upon one occasion I found three in a nest." 



In my account of this species, I have stated that it was found in Guatemala as well as Mexico ; and although 

 this may be the case, I beUeve the latter country to be its true habitat. Guatemalan differ from Mexican specimens 

 in the colouring of the tail-feathers ; in the latter they are olive-green, in the former rich bronzy-green. Under 

 these circumstances I cannot regard them as identical, I must therefore give the Guatemalan bird a distinctive 

 appellation: —

Habitat, Guatemala. 



" Last year, in a cypress tree near the house at Dueiias, a pair of these birds built their nest. This year I found 

 a branch of the same tree similarly tenanted, the new nest being only a few yards from the site of the old one. To 

 obtain it, I was obHged to cut away the branch ; and though, in falling, the nest was quite thrown on its side, the 

 eggs, much to my surprise, did not fall out : this I afterwards found was owing to the lip of the nest tumino- 

 inwards. Another pair commenced building near the house; and the male bird frequently came while I was 

 preparing skins in the corridor, and took pieces of cotton almost from my hand. In the afternoon of August 14, 

 my friend Mr. Wyld observing it making a descent upon some small object in his room, shut the window and called 

 me. The intruder, who was wearied from fluttering against the window, suffered itself to be caught. In a very 

 few moments its agitation ceased, and it seemed to be taking advantage of its comfortable place in my hand to rest 

 fi'om its fatigues, making no attempt to escape. Before letting it go, I procured a piece of sugar, and, after dipping 

 it in water, put it to the tip of its bill. Almost immediately its long tongue was employed in sucking up the 

 liquid. On liberating it, it flew to a tree close at hand, and seemed to take no further notice of its late captivity."
