It is very common in all the States, and one of

Dendroica Aestiva.—Baira. 
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.
