I believe it also helps that they live in social groups, aside from some solitary males.

So we're tracking (population / avg_group_size + misc_males) objects, as opposed to the entire population.

Example on the other end would be snow leopards (130+ sq km) and grizzlies (380+ sq km), which are mostly solitary and have huge ranges.

If there are really 1063 I would think conservationists could know about almost every one individually. That's smaller than the high school I went to. I know they are spread out over a wide area in a dense jungle but I think it would be possible.
