Give each animal or bird a unique tag so identification of each animal/bird is very easy
Can locate each animals and track their movements in huge farms.
Track feeding rates, incubation behaviour, behaviour by non- breeding birds/animals, homing behaviour and other areas of interest.
Ornithological research: Radio frequency identification (RFID) technology allows the unique identification of individuals and automated recording of the presence of tagged birds at fixed locations. This information is used to examine questions related to pair formation, feeding rates, incubation behaviour, prospecting behaviour by non-breeding birds, temporal changes in body condition, post fledging movements, dispersal, homing behaviour, and other areas of ornithological interest.
RFID technology can be linked with other instruments, such as automated weighing devices, video cameras, infrared beams to detect the direction of movement, and temperature loggers, to collect additional data.
Inexpensive RFID technology has removed cost as a major constraint to the wider implementation of RFID in ornithological research.
Retention: Traditional visual tags can get lost or damaged easily. An RFID tag stores its information electronically, and is small and unlikely to get lost, and so the ID information won’t be lost either.
Speed: Since RFID systems need only 3 to 12 inches between the reader and the tag, it’s much faster to get information on all the cattle that need to be identified. You can even set up passive checkpoints where the ID of each animal that passes through, such as onto a truck or into a barn, will be scanned.
Accuracy: Since the data is handled entirely electronically, human error is all but eliminated.
