 The stomachs of 230 Flickers examined showed animal food 56 per 

 cent.; vegetable food, 39 per cent.; mineral food, 5 per cent. Of the 

 animal matter, which was insects, the percentage was divided as fol- 

 lows: Ants, 43 per cent.; beetles, and their larvEe, 10; caterpillars, 1; 

 grasshoppers, 1; spiders and myriapods, 1 (Beal, Bulletin No. 7, Div. 

 0. and M., U. S. Dept. Agr., p. 11). Several stomachs contained noth- 

 ing but ants. In two, the actual number of ants in each stomach ex- 

 ceeded 3,000 (Ibid, p. 17). The vegetable material it eats is principal- 

 ly that which grows wild.
