Food Habits of the Sharp-Tailed Grouse by Analysis of Droppings

The technique has, however, been used in numerous studies of predatory mammals. Dearborn (1932) published the first comprehensive food habits study based on analysis of feces, applying the method to 9 species of predatory furbearers in Michigan. Hamilton (1933) studied the food habits of the big brown bat by use of the droppinganalysis method. 0. J. Murie (1935) and Bond (1939) have used the method extensively on coyotes. Errington (1935, 1937a), Hamilton (1935), Hamilton, Hosley, and MacGregor (1937), and A. Murie (1936), have all applied it to the red fox. It has been adapted to study of the food habits of skunks by Hamilton (1936), Kelker (1937), Selko (1937), and Wight (1938). Errington has also used the method on badger (1937) and weasel (1936), and Giles (1939) has applied it to the raccoon in Iowa.
