I think Copper Blangos are just better hidden and protected by their parents, and don't go far from the nest caves so that they aren't found yet. Maybe they leave the nest completely when they're almost adult so that there aren't many young Blangos roaming outside. And I also think that they birth only a few youngs while normal Blangongas have more what makes it much more important to protect the few youngs for survival.
