One way to quantify a prey’s response to a predator is by flight initiation distance (FID), the distance between a predator and prey at the moment the prey flees. As perceived risk from a predator increases, FID increases. Juvenile animals typically flee from approaching threats sooner than do adults because they have less able risk assessment. However, our observations suggested juvenile squirrels might use a different tactic: foraging near refuges. We first tested whether age affected squirrels’ FID in response to an approaching human on the UofL campus, where squirrels experience high levels of interactions with humans from an early …
