Favors tall grasslands, shrub habitats, woodland with an open canopy “cerrado”, and wet fields (which may be seasonally flooded). Some evidence indicates that they may prefer areas with low to medium shrub density. Maned Wolves are also seen in cultivated areas and pastures. Daytime resting areas include gallery forests, cerrado, and marshy areas near rivers. There is some evidence that they can utilize cultivated land for hunting and resting, but additional studies are essential to quantify how well the species tolerates intensive agricultural activity.

Omnivorous, consuming principally fruits and small- to mediumsized vertebrates. Numerous studies document a broadly varied diet of c. 50% plant and c. 50% animal material.

, and others), reptiles, and arthropods. Although the frequency of plant and animal items found in fecal samples is approximately equal, the biomass of animal items is usually greater than that of plant items. Certain items, such as rodents and Solanum, are consumed year round, but diet varies with food availability. At least occasionally, Pampas Deer (Ozotoceros bezoarticus) are also consumed. In one study, deer occurred in 2:4% of 1673 fecal samples analyzed. Strategies for hunting animal prey include stalking with a final pounce, digging after burrowing animals, leaping into the air to capture flying birds and insects, and sprinting after fleeing deer. Approximately 21% of all hunting attempts end with the successful capture of prey, and the strategies do not differ in their success rates. Maned Wolves have been recorded feeding on Coypu that were caught in traps set by hunters, and have been observed scavenging opportunistically on road-kill carcasses.

? n = 5) in Emas National Park. Home range boundaries appear stable over time and are defended against adjacent pairs. Termite mounds are preferentially used as urine-markingsites, and more marks are placed on the upwind side of objects than on the downwind side. Floater individuals without territories appear to move along territory boundaries and do not scentmark. The most frequently heard vocalization is a loud roar-bark, which may occur during any time of the day or night throughout the year.

Females enter estrus once per year for approximately five days. Peak breeding season is from April to June. There are numerous published accounts of breeding behavior in captivity, but little information is available from wild populations. In captivity, the frequency of vocalizations (roar-bark) and scent marking increases during the weeks prior to mating, and the amount of time a pair spends in close proximity increases significantly during the estrous period. Courtship is characterized by frequent approaches, mutual anogenital investigation, and playful interactions. Mounting may occur frequently during estrus; successful breeding includes a copulatory tie that may last several minutes. In Emas National Park,

, a breeding pair observed at night for approximately three and a half hours foraged together and vocalized frequently whenever one partner was out of sight. The male marked with urine or feces wherever the female marked. A breeding display lasting ten minutes concluded in a two-minute copulatory tie, after which the pair continued to forage together. Gestation length is approximately 65 days, the majority of births occurring from June to September, during the dry season. One female gave birth to three pups in a bed of tall marsh grass. At 45 days of age the pups had notyet left the den and weighed

In captivity, an analysis of 361 births indicated that parturition peaks in June (winter), and the average litter size is three (range 1-7). Birth weights average

from their den sites and pups. Pups stay in the mother’s home range for approximately one year, when they begin to disperse. Juveniles attain sexual maturity at around the same time, but usually do not reproduce until the second year. One of the many unknown aspects of Maned Wolf behavioris the role the male plays in rearing pups. Pups have been seen accompanied by

, they appear to be more common. The most significant threat to Maned Wolf populations 1s habitat reduction, especially for agricultural conversion. The cerrado, for example, has been reduced to about 20% ofits original area, and only 1-5% is currently protected. In addition, habitat fragmentation causes the isolation of sub-populations.

, especially for young individuals and sub-adults. Highways border many of the Conservation Units of the Brazilian cerrado, and drivers often do not respect speed limits. Reserves close to urban areas often have problems with domestic dogs, which pursue and may kill Maned Wolves and can also be an important vector of disease. Diseases may represent a significant cause of mortality in the wild, but there is very little information available on the health of wild populations. Domestic dogs also possibly compete with the Maned Wolffor food. Maned Wolves are not viewed as a serious threat to livestock, although they may occasionally be shot when caught raiding chicken pens. Hunting them is prohibited in
