Contents of the Crop and Gizzard of a Young Ruffed Grouse (Bonasa 
umbellus). — The following is the result of the analysis made by the U. S. 
Department of Agriculture, of the contents of the crop and gizzard of an 
immature specimen of this species, captured July 18, 1906: 
“3 percent of the food is animal, consisting of the following: 
1 Carabid beetle 1 Tettigoniid 
1 Leptura vibex 8 Camponotus pennsylvanicus 
8 Plagiodera armorieice 1 Snail 
1 Pyropyga nigricans 
“97 percent is vegetable matter made up as follows: 
About 105 seeds of touch-me-not (Impatiens hiflora), 22 %. 
About 1750 seeds of blackberry {Rubus sp.), 31%. 
8 seed pods of violet (Viola sp.) containing approximately 25 seeds each, 
together with 114 free seeds, making in all about 514 seeds of this species, 
14%. 
About 100 seeds of ground cherry (Solanum sp.), 2%. 
About 462 seeds of sedge {Carex spp.), twelve being in perigynia, 4%. 
2 pods of Juncus sp. with many seeds, 1%. 
About 8 seeds of grass, 2%. 
A few seeds of Oxalis sp. and a few unidentified, 1%. 
Some bits of dead leaves and green browse, the latter probably from 
touch-me-not, 20%. 
“Mineral matter consisting of 2 pebbles, is 2% of the entire bulk.”—
