50 bobcats (Lynx r. rufus) were collected in Minnesota in 1938-39. Trail notes were used to interpret food habits indicated by stomach analyses. Hare (Lepus americanus), deer (Odo-coileus virginianus), and porcupine (Erethizon dorsatum) comprised > 90% of the food. The deer was largely carrion. No poultry or domestic stock were found. Damage to deer and grouse (Bonasa umbellus) attributed to bobcats is negligible. Its food habits are considered beneficial. A state bobcat bounty appears to be unnecessary. In recent yrs. the northern limit of range for the bobcat has extended to include southern Ontario. Spruce-cedar swamps are preferred winter habitat. Winter range is no more than 10-15 sq. mi. An av. of 51/2 mi. was traveled in a night''s hunting. Stalking is a favorite method and elevated "lookouts" along game trails often are used. Droppings usually are deposited off the trail, preferably on an elevated spot and sometimes are covered. Bobcats spend the day mainly in temporary "rest shelters." 13 spp. of parasites were recovered from 50 bobcats: Toxacara cati (new record) from 21 animals; Toxascaris leonina from 2; Physaloptera praeputialis horn. 1; Physaloptera sp. from 1; Ascarinae from 2; Spirocerca sanguinolenta (new record) from 1; Toxacara sp. from 1; Taenia taeniaeformis from 7; T. pisiformis (new record) from 5; T. hydatigena from 3; T. rileyi (new record) from 2; T. monostephanos (new record) from 1; and T. krabbei from 1.
