And the standard RFID microchip implants (such as the ones AVID supplies) are not actively trackable. They're merely transponders that emit a unique digital number when scanned from very close range, but no GPS tracking signal. You can have an RFID chip implanted by a vet for around $25 to $50. The ones Shelly is talking about, though, must be GPS trackable devices based upon the price range she has given. Devices such as those would require that a battery be attached to your bird to serve as a power source for the transmitter - unlike the AVID chip implants which require no power because they cannot transmit a signal on their own.
