rows. Botli birds assist, in iiievihation, wliieh takes about fourteen 

 (lays. They must, lay sometimes in February and Mai"ch. April 24, 

 1878, Dr. Brayton shot, near Indianapolis, a number of Shore Larks, 

 among them two young birds about grown (Bulletin Nutt. Orn. Club, 

 1878, p. 189). 



Its food consists principally of seeds of different grasses, like those 

 of pigeon, foxtiiil and Hungarian (Setaria); also of those of different 

 species of Polygonum (bindweed, knotweed and smartweed), those of 

 the ragweeds (Ambrosia), pigweed (Chenopodium), etc. 



Broken kernels of oats and other grains have also been found in 

 their stomachs, evidently picked up in the roads and streets among 

 the droppings of horses. During spring and summer, when small in- 

 sects abound, a portion of their food consists of young locusts and 

 grasshoppers, small beetles and their larvae, and hairless catei'pillars, 

 and the young nestlings, at least, are fed on insect food. From an 

 economic point of view, all our Horned Larks must be considered as 

 useful birds, doing far more o(M)d than harm (Bendire. L. H. N., A. B., 

 IL, p. 385). 



The little harm they do is more than l)alanced by the destruction 

 of weed seeds and of injurious insects.
