Originally described by Swainson from a specimen sent to 

 Mr. John Taylor from Real del Monte, in Mexico, this 

 species extends throughout the Mexican highlands from 

 Mazatlan to the Gineta Mountains, being met with at many 

 intermediate points, such as Cordova, La Parada, and Cinco 

 Senores. In Guatemala it has also a wide range in the oak 

 forests of the highlands. It is common in the Volcan de 

 Fuego, between 7000 and 9000 ft. above the sea. It is also 

 to be found at many points on the mountain-range which 

 forms the northern edge of the valley of the river Montagua. 

 Here Mr. Godman and I met with it above the villages of 

 Choi, San Geronimo, and Santa Barbara ; also in the higher 

 district of Chilasco, and near Tactic in Vera Paz. 



This is a conspicuous species, soon attracting attention by 

 its restless movements amongst the branches of the forest 

 trees and by its habit of opening its tail to exhibit the white 

 tips of the rectrices. 



Prof. Baird remarks (Rev. Am. B. p. 257) that he had 

 never seen an authentic female of this species. Neither have 

 I ; but a specimen which I believe to belong to that sex hardly 

 differs from the male, the colour of the breast being only 

 somewhat less brilliant in tint. And on this point Mr. Hen- 

 shaw's observations are conclusive; he says that the sexes 

 differ little, the female being merely perceptibly duller 

 throughout. 



Prom Mr. Henshaw^s remarks, S. picta appears to breed 

 in Southern Arizona and to migrate southwards in winter ; 

 the dates when his specimens were obtained range from 

 the 20th of July to the 2r)th of September. In Guatemala, 

 I believe, it is found throughout the year ; and as we have 

 a Guatemalan specimen in first plumage, the species must 

 breed in that country, though I have no further positive 

 evidence of the fact. As it does not occur beyond the
