Gentry says : “ The food of these birds is less of an insect character 
than that of any other of the Picarian family. Although a great de- 
stroyer of insects in their most destructive stages, yet the untold mis- 
chief which they achieve in the perforation of the inner bark of many 
trees to such an extent as to kill them, fairly outbalances the immense 
good which they accomplish. In some parts of Wisconsin, this destruc- 
tion is perpetrated on a grand scale. In 1868, Dr. Brewer, in company 
with Dr. Hoy, visited Bacine, and witnessed the results of this perfora- 
tory process. The punctures were made into the inner bark of trees, 
and Avere so close together that the bark eventually became stripped off, 
causing a complete and fatal destruction of them. In one garden, all 
the mountain-ash and white pine trees Avere entirely killed.” 
In referring to these sap-sucking woodpeckers. Dr. Cones says : 
“Birds of this remarkable genus feed much upon fruits, as Avell as in- 
sects, and also upon soft inner bark (cambium) ; they injure fruit trees 
by stripping off the bark, sometimes in large areas, instead of simply 
boring holes. Of the several species commonly called ‘ Sapsuckers,’ 
* Yellow-bellied Sapsuckers have been very common the last two seasons ('88, ’89) in the spring. The 
city (Scranton) was full of them; some killed themselves by flying against windows. — Geo. P. Friant 
t S. varius arrives early in spring, is then quite plenty; disappears soon, however. Know of one in- 
stance where it bred. This bird rarely visits our orchards, therefore cannot do much damage to any- 
thing. — A'uoust Koch.
