Capturing rodents, nonhuman primates and birds who have escaped from their primary enclosure does not need to be a chaotic event and does not necessitate the use of stress-inducing, possibly injurious methods in most cases. The application of basic ethological principles plus compassion can make a big difference, turning the recapture procedure into a harmless event both for the escapee and for the personnel.
