Parila Americana.— Bonap. 
Blue Yellow-back. 
It is very abundant from Georgia to Maine. 
I have not found it as plenty in the West. 
I found it breeding in New Jersey. Its nest is 
made of moss. Eggs four or five in number. 
Geothlypis Trichas.—Cab. 
Maryland Yellow-throat. 
It is very abundant in the Spring in all the 
States, and breeds from the Atlantic to the 
Mississippi. Eges four in number, and often a 
cow-bird egg. 
Geothlypis Philadel phia.— Baird. 
Mourning Warbler. 
This bird is considered rare among most 
collectors. I have found it from Delaware to 
New York, and from the Atlantic to Iowa, but 
have never found it breeding. Its habits are 
very much the same as the Geothlypis Trichas. 
Geothlypis Mac gillivrayt—Baird. 
Macgillivray’s Warbler. 
I never found this bird until 1874, and then I 
shot three specimens in one day in the State of 
lowa. It resembles the Mourning Warbler in 
appearance very much, and its habits are very 
near the same. It is found in Iowa. The speci- 
men is in my collection.
