In Israel, groups of hyenas converge at feeding sites (Kruuk 1976, Macdonald
1978, Bouskila 1984), but relatedness of observed groups has not been investigated.
Foraging activity in Tanzania was restricted entirely to night-time (Kruuk 1976). Striped
hyenas have also been described as raiding human grave sites and carrying away bones
(Horwitz 1988, Leakey 1999), and fruit and vegetable crop raiding is considered a serious
problem in Israel (Kruuk 1976).
