behavioral responses shown tend to be hiding and flight initiation distance (FID, the distance between the animal and the predator before escape is attempted). Levels of expression in both chemical and behavioral responses can differ depending on color variation of the throat. Chemical levels in both O and OB males can change significantly when predators are spotted. When encountered with a predator, the lizard's corticosterone levels in both O and OB males spike, but both types of males have the same hormone levels. When looking at testosterone levels in both O and OB males when encountering a predator, both males testosterone levels spiked, but the O males had higher testosterone levels than the OB males. When looking at behavioral responses there is also a difference in hiding time and flight distance. When encountering a predator O males have a larger flight distance compared to OB males, meaning that O males will escape when a predator is farther away when compared to an OB male, which will let the predator get closer before escaping. Hiding time differed between O males and OB males, where O males had significantly longer hiding periods after the encounter with the predator when compared to OB males. Overall OB males express lower chemical levels, shorter flight distances, and shorter hiding periods when encountered with a predator compared to O males. The differences in anti-predator behavior can be attributed to the binding capacity of plasma binding globulins. Binding globulins regulate steroid hormone impacts on behavior and physiology in the body can cause differences in hormone levels which can affect changes in behavior. When bound to a corticosteroid-binding globulin (CBG), plasma corticosterone may not diffuse into target cells, and thus, sensitivity of individuals to circulating corticosterone can depend on binding capacity and level of CBG. The binding affinity of the androgen-glucocorticoid-binding globulin (AGBG) in tree lizards is similar between the territorial OB and nonterritorial O males, but AGBG has a greater binding capacity in OB males. Nonterritorial O males have higher levels of free corticosterone than do territorial OB males during stressful events due to the differences in binding capacity and levels of CBG. This free corticosterone difference could contribute to the higher behavioral reactivity - greater flight initiation distances and longer hiding duration - of O males compared to OB males in response to predation risk.
