A slender, long-legged deer of South American grasslands. In Argentina, current populations remain in limited areas.
Coat color varies by region and individual. Females are slightly smaller than males, and only males have branched antlers.
At Los Ajos ranch in Rocha, southeastern Uruguay, ten deer of the Uruguayan pampas deer subspecies were radio-tracked for two years. Their average home range was 5.54 square kilometres, with a standard deviation of 3.18 square kilometres. The 0.87-square-kilometre core area overlapped crop fields used for beef-cattle grazing.
The studied population showed philopatric behaviour, and total range size did not differ significantly by sex or season. Its core-use area and cattle-grazing crops occupied the same ranch landscape. The deer’s movements at Los Ajos therefore crossed a working agricultural area rather than a separate block of habitat.
An extinction-risk assessment has not been added yet.
In Rocha, southeastern Uruguay, a two-year study tracked ten deer of the Uruguayan pampas deer subspecies. Their core use area overlapped crop fields used for beef-cattle grazing, showing how this local herd’s range intersects with ranching land at Los Ajos.
