This species has a somewhat restricted range, being confined to the eastern slope of 
the mountains of Southern Mexico, Yucatan, and thence southwards to the highlands of 
Vera Paz. Sumichrast says it is very common in the hot and temperate zones of the 
Department of Vera Cruz up to an elevation of about 4000 feet; he adds it is a bird of 
the woods and less sociable than the rest of its tribe. In Yucatan Mr. Gaumer speaks 
of it as one of the commonest birds, that it is abundant in all the towns as well as in 
the forests, that he has seen it in the busiest streets of Merida, even entering houses in 
search of food. In Guatemala its range is very restricted, and it is first met with near 
the village of Tactic (that is, near the border of the most rainy district of Alta Vera Paz) ; 
and it is quite common in Coban, where it frequents the fruit and other trees so freely 
distributed about the town.
