Summer food habits of coyotes (Canis latrans)in the River of No Return Wilderness Area, Idaho, were determined. Analysis of 51 scats (fecal samples) revealed that Columbian ground squirrels (Spermophilus columbianus), mule deer (Odocoileus hemionus), and deer mice (Peromyscus manniculatus) exhibited the greatest frequency of occurrence for identified food items, being detected in 57%, 27%, and 16%, respectively, of scats examined.
