Summary
This field study used scent-baited RFID antennas to measure how marked urban brown rats responded to male and female rat odors in sheltered and predator-exposed locations. Male scent prompted brief inspection regardless of risk, whereas female scent caused much stronger and longer-lasting attraction that was greatest near shelter, separating odor valence from perceived danger. UID RFID microchips connected more than forty days of visits to individual rats.
