tarian), the warblers chiefly insectivorous. For 
_ this reason finches are not so migratory as war- 
blers, whose resources of food are almost en- 
tirely swept away by cold weather, so that there 
is only one warbler (the yellow-rump) that can be 
found in the Northern States during the winter. 
The scientific designation of the warblers as 
syluicolide (living in the woods), although not 
profoundly descriptive, is not misleading, and 
points to an evident characteristic of the class. 
They are more retiring than many other species, 
and are found in woods and groves rather than 
by the wayside or in the open pasture. 
In this region the finch and warbler families 
are equally represented by about forty species in 
each. ‘Throughout North America there are 
twice as many finches as warblers, one hun- 
dred and twenty-three to sixty-two, and in the 
world five hundred species of finches (the largest 
of all families), and upward of one hundred 
species of warblers. 
These points of comparison touch upon the 
most important aspects in the life-history of the 
two families. )
