Dendrotca Pennsylvanica —Baird. 
Chestnut-sided Warbler. 
It is very common all over the country. I found 
it breeding in the mountains of New York, and 
in the State of Minnesota. Eggs four to five in 
number. 
Dentroica Cerulea—Baird. 
Blue Warbler. 
It is very rare in the Eastern States. I have 
found it very abundant along the Mississippi 
River, in Iowa. 
Dendroica Striata—Baird. 
Black-poll Warbler. 
It is very common in all the States, and one of 
the latest to arrive in Spring. It breeds in Maine 
and Iowa. 
Dendroica Aestiva —Baird. 
Yellow Warbler. 
This is the most common of all the warbler 
tribe, and is distributed all over the country. 
I have found it breeding in gardens near houses, 
and it appeared to be very tame. I have met 
with it on the prairies where there were no 
dwellings within tea miles. Its nest is made of 
hemp, and generally lined with wool and twine. 
Eggs four to five in number.
