This species, taken as a vs'hole, is subject to a great amount of variation, not only as 

 regards the intensity of the colour of the back and under surface, but also as regards 

 the rosy spot on the throat. The females also vary in the intensity of their general 

 rufous coloration. The darkest males are found in the province of Tabasco, and thence 

 southwards through Eastern Guatemala, and northwards along the coast of the State of 

 Vera Cruz to Tampico. At Jalapa and in the Eastern Sierra Madre the back is 

 generally a little greyer; and this is the case in birds from the Tres Marias Islands, the 

 mountains facing the Pacific coast of Guatemala, and also in those from Nicaragua. The 

 palest examples are from Western Mexico, in which the back is grey and the under 

 surface nearly white, and with these specimens from the northern part of Yucatan agree 

 very closely. The assumption of the rosy spot of immature males appears usually to 

 commence at an early stage, and is often of full size before the wing-feathers have 

 assumed their adult coloration. In other specimens, which are apparently fully adult 

 in other respects, this rosy spot can barely be traced. We have already referred to the 

 variation in the rufous colouring of the female ; the crown of the head also varies from
