ECONOMIC RELATIONS OF OUR BIRDS. 
182. Zenaiduba Carolinensis (Linn.), Bp. CAROLINA DOVE. Group I. 
Class c. 
A very common summer resident but never sufficiently gregarious to be inju¬ 
rious to crops to any noteworthy extent. 
Food: Seeds of various weeds, buckwheat, rye, wheat and oats. In the stom¬ 
ach of one bird I counted 4,016 seeds of the pigeon-grass and twelv'e small snails; 
the latter were probably taken as gravel. Of nine specimens examined, eight 
had eaten the seeds of weeds; three, wheat; two, rye; and one, oats. 
Buckwheat, hemp-seed, coim, beri'ies, acorns, and occasionally peas (Wilson). 
Grains and berries (Samuels). Seeds, grain, buckwheat, Indian corn (Brewer). 
Of four specimens examined, four had eaten seeds of weeds; two corn; and one, 
wheat (Forbes).
