Except along our northern frontier Sphyropicus varius is probably only a winter 
visitor to Mexico and Central America. All our records of it refer to that time of 
year, nearly all the dates ranging from November to March and the beginning of April. 
Mr. Richardson found it as late as May in the sierras of Tamaulipas; but possibly 
the specimens he obtained would have bred in the district. 
In the United States the “ Yellow-bellied Woodpecker” or ‘Sap-Sucker,” under 
which names S. varius is known, is a common bird, arriving in April and May and 
remaining to breed. It is well known in the New England States and has even been 
recorded from Greenland. 
Its winter resorts include Central America as far south as Honduras and Northern 
Nicaragua—that is, as far as the southern extension of the upland pines. It also occurs 
in many of the West India Islands. Mr. Cory mentions several of the Bahamas, 
Gosse and others the island of Jamaica, and Dr. Gundlach Cuba, where it arrives 
every autumn on passage. 
The range in altitude of this species in its winter-quarters is very considerable, for 
it occurs in Northern Yucatan near the sea-level and in the upland pine-region of the 
higher volcanoes of Guatemala at least 10,500 feet above the sea. It is, however, 
most commonly met with in the highlands between 4000 and 8000 feet. 
In 1891, Mr. Frank Boller published an interesting account of the feeding-habits 
of this species in a paper entitled “ Yellow-bellied Woodpeckers and their uninvited 
Guests”. From his observations he concludes that this species is in the habit for 
successive years of drilling. holes in several kinds of trees for the purpose of taking 
from them the “ elaborated sap” and sometimes the cambium-layer of the bark; that 
the birds consume the sap in large quantities for its own sake and not for the insects 
which it occasionally contains; that the Sap attracts many insects of various kinds, a 
few of which form a considerable part of the food of this bird, but whose capture 
does not occupy nearly so much time as sap-drinking ; that different families of these
