We can pretty much always identify within a few hundred meters, of where the animals were taken from in the wild and confiscations in this case are not from pet trade, they’re from poachers and generally take place a few hours after the poaching event. Often as the poachers are returning from the forest, or when they are attempting to transfer them off the island.
In any case, we are on an island and all the of the animals come from this island, so the exact location isn’t all that important considering that the island is only 27 km by 23 km (roughly) and the wildlife is more-or-less evenly distributed across it.
We keep the animals for at most 2 days, generally far less, often only a few hours. Whenever possible I insist on a field evaluation and an immediate release as the holding facilities are poor.
In our situation, in my opinion, there is no justification for marking the animals captive.
Of course, we are in something of a unique position and many others are not in this same situation. That said, for on-the-ground conservation organizations and wildlife rescue operations this is not an uncommon position to be in.
While I approve of a vote system in general, there are times where I feel that obviously wrong votes (or identifications) should be over-ruled by the initial observer, especially when the other party refuses to respond to communication.
