Figure 2.— Statistical comparison of wing measurements of subspecies 

 of white-winged doves. 



The present studies indicate that asiatica does not occur as a breeder 

 anywhere on the mainland south of the Isthmus of Tehuantepec, 

 and mearnsi may not breed south of northern Sinaloa. 



Morphological differences between populations are not great, and 

 in several races the general trends do not conform to the classical 

 rules of morphological variation correlated with climate. In general, 

 long-winged birds are characteristic of the higher altitudes and more 

 temperate areas, and short-winged birds are typical of the tropical 

 lowlands of the Gulf and Caribbean. However, some of the subspecies 

 having the longest wings and tails are those in tropical lowlands of 

 some Pacific coastal localities from Mexico south to northern Chile.
