In a paper on Tinnunculus sparverius and its allies by Mr. Edgar Meams*^, the 

 author recognizes an eastern and a v^estern form, the latter being separated by him as 

 T. deserticolus. The characters for the separation of T. deserticolus depend chiefly 

 upon the plumage of the female, the male presenting no definite peculiarities. While 

 acknowledging that specimens from Western North America difier as regards the 

 barring of the tail and some unimportant characters, we have in our collection eastern 

 birds, and others, more or less intermediate, which cannot be distinguished from the 

 western form. The range of T. deserticolus has been traced by Mr. Meams to 

 Mazatlan *^, and by Prof. Allen to Sonora ^^, and we have specimens from Guatemala 

 and Nicaragua which appear to be likewise referable to this western race. 



With the exception of the Arctic portions of the North-American continent, this 

 Kestrel is distributed in summer over the greater part of the United States and Canada, 

 being most plentiful in the western and southern regions. According to Grayson ^^, 

 T. sparverius probably breeds also in certain portions of Central America ; we ourselves 

 found the species generally distributed in Guatemala, where we believed it to be 

 migratory; but in Mexico, &c., Sumichrast, Richmond, Cherrie, and other good 

 observers record the bird as a winter visitant only. On Popocatepetl and Ixtaccihuatl
