     Thermal imaging has been successfully applied in veterinary and conservation contexts (e.g., examining injuries or monitoring inconspicuous species). Recently, it has been used to measure emotional reactivity of captive primates. To explore the utility of such technology, we investigated thermal imaging applications for monitoring both the physical and psychological well-being of several primate species. In chimpanzees, we found that certain thermal images may provide accurate measures of core body temperature: armpit and ear temperatures from thermal images were not significantly different from rectal temperatures [t(2)=-1.59, p=0.25 and t(4)=-1.05, p=0.35 respectively], whereas upper back [t(3)=3.85, p=0.03] and forehead temperatures did differ significantly from rectal temperatures [t(5)=-2.79, p=0.04]. When tracking reproductive cycles of baboons, we found maximum temperature differed between anogenital swelling sizes [t(7)=-2.450, p=0.04], while average temperature did not [t(7)=-1.70, p=0.13]. Thermal images also revealed high temperatures of outdoor structures within baboon and chimpanzee enclosures, even on days with moderate atmospheric temperatures (outside: 74.3-91.0°F; structures: 89.0-153.1°F). Thermal imaging can also be used as a non-invasive tool to monitor wound healing, as well as in the measurement of emotional responses to potentially negative (e.g., physical exams) and positive (e.g., training) events (using nasal and ear temperatures). Thermal imaging may reduce the need for handling and invasive monitoring, and may provide a straightforward opportunity to measure the effects of modifications to the physical environment in captive primate facilities.
