We recorded the occurrence of hip glands in a population of montane voles (Microtus montanus) in southeastern Idaho. Sexual maturity was positively associated with the presence of hip glands in both males and females. Significantly more males than females possessed hip glands. Males and females with hip glands were significantly heavier than individuals without glands. The possible function of hip glands in scent marking, aggression, and population fluctuations is discussed.
