during early summer (Hamer and Herrero, 1987). Their study also revealed that ants<br />

(Formicidae) were common in bear’s diet. Of the 329 scats analyzed from early May<br />

to early September, 161 (49%) contained ants. In Greece, brown bear diet was<br />

dominated by food items of plant origin (87%), followed by animal material (13%),<br />

mostly composed of insects. Grasses and fleshy and dry fruits composed the major<br />

proportion of the vegetable part in the bear diet (Mertzanis, 1994). Brown bears in<br />

Scandinavia were found to forage in the early spring on ants (Formicidae) they<br />

excavated from large ant mounds (Elgmork and Unander, 1998). Of the 143 ant<br />

mounds recorded along the tracking routes, 63 (44%) were excavated by bears. Of<br />

these, 54 (86%) were used for food and the study also revealed that brown bears used<br />

large ant mounds for 3 purposes: for nutrition, as day beds, and for winter dens. In<br />

Sweden, Bjorklund (1996) reported that bears resting on ant hill might be benefited<br />

from the formic acid sprayed by the ants on the fur, which acted as a repellent against<br />

ectoparasites. Ohdachi and Aoi (1987) collected seasonal food habits information<br />

from 1975 to 1984 in 4 diverse areas on Hokkaido island and found that bears food<br />

varied seasonally in each area and differed among areas largely because of differences<br />

in food availability. Their study revealed that brown bears on Hokkaido Island were<br />

principally vegetarians, and animal material was only 5% by weight of the annual<br />

diet. Ants were the most abundant animal material. Food habits of European brown<br />

bears have also been investigated by Couturier (1959), Berducou et al. (1982, 1983)<br />

and Dendaletche (1982) in France, and by Zunino (1976) in Italy.<br />

Food habits of brown bears have been studied in Plitvice Lakes National Park,<br />

Yugoslavia by Cicnjak et al. (1987) by analyzing 95 scats and plant material was<br />

found in 76% of the samples, whereas 24% contained both plant and animal material<br />
