The easiest way to tame them is take an argy with you to the swap, then locate a kapro and scoop it up with your argy also make sure you bring a high level eagle with enough health so it won’t get killed by the kapro. Then drop the kapro at a safe place and make sure to set your bird to passive so it won’t kill your kapro. Then shoot it a tranq dart (one should be enough) and start taming. Then once it’s tamed just scoop it up with your eagle and bring it home. If your argy is running out of stamina be careful where you land because kapros die very easily. (I’ve lost about 20 kapros because they fell into some phirannhas until I finally was able to get one home) taming them isn’t hard, it’s keeping them alive until they are a decent level that is hard
