Scientists are currently monitoring about 125 of those adults and 50 juveniles via radiotelemetry so they can keep tabs on their health and movements.

The radiotelemetry devices that had been implanted could then be “recovered” from the bodies, the proposal said.

Indeed, Campbell trained local hunters to perform field surgery on female goats—tying their fallopian tubes, terminating any pregnancies and inserting hormonal packs so that they were in constant heat, after which they were outfitted with radiotelemetry transmitters on collars so they could be traced.

The last thing to do before sleep is prepare for the next morning, when we’ll break out the radiotelemetry gear and check on a couple of monkeys.

The tags used by the researchers enable their team to track the birds' daily flights using radiotelemetry and GPS technology.
