All imported birds will have to be individually identifiable through a leg-ring or microchip implant.

The species are marked either by open/closed leg-band or by microchip implant.

Each animal has a subdermal tracking microchip implant.

A microchip implanted in the wheel transmits the findings to the satellite navigation screen every few minutes.

Think of this, and think of having a microchip implanted into your hand.
