Extent of threat detection depends on predator type and behavioral context in wild samango monkey groups by LaBarge, Laura R., Allan, Andrew T. L., Berman, Carol M., Hill, Russell A., Margulis, Susan W.

“…Detecting predators requires information, and many behavioral and environmental features are predicted to enhance or limit an animal’s ability to learn about…”

Habituation is not neutral or equal: Individual differences in tolerance suggest an overlooked personality trait by Allan, Andrew T L, Bailey, Annie L, Hill, Russell A

“…In behavioral studies, observer effects can be substantial, even for habituated animals, but few studies account for potential observer-related phenomenon…”

Consistency in the flight and visual orientation distances of habituated chacma baboons after an observed leopard predation. Do flight initiation distance methods always measure perceived predation risk? by Allan, Andrew T. L., Bailey, Annie L., Hill, Russell A.

“…Flight initiation distance (FID) procedures are used to assess the risk perception animals have for threats (e.g., natural predators, hunters), but it is…”
