WESTERN TAX ACER. 



Synonym Pyranga ludoviciana. 



Status Summer visitant in the Transition zone and upward, of common oc- 

 currence in the north: San Francisco Mountain (Merriam, 1890, p. 40) ; Mogol- 

 lon Mountains (Mearns, 18903, p. 260). In diminishing numbers to the south-

 Mountains (Swarth, 1904!), p. 47). These latter points, where it is of rare oc- 

 currence in the summer, probably indicate the extreme southern limits of the 

 breeding range of the species. Common and generally distributed during the 

 migrations.
