Which behavior is common for Northern Fence Lizards when threatened?

Northern Fence Lizards exhibit a behavior known as autotomy, which involves shedding part of their tail when threatened by a predator. This tail shedding can distract the predator, allowing the lizard to escape while the predator is preoccupied with the detached tail's movements. Once the lizard is safe, it can eventually regrow its tail over time, although this regenerated tail will differ in appearance and structure from the original.

The other behaviors listed—feigning death, chirping loudly, and burrowing into the ground—are not typical responses of Northern Fence Lizards when they face danger. Each of those responses is commonly observed in different species across various contexts, but they do not accurately describe the escape strategies of Northern Fence Lizards. Understanding this behavior provides insight into how these lizards have adapted survival mechanisms in their natural habitat.
