Why Do Goitered Gazelles Cross the Path of an Approaching Moving Object Instead of Fleeing?

Animal–vehicle collisions are an important conservation concern. Although many studies examine road mortality and wildlife crossings, less is known about ungulates that run across the path of an approaching vehicle rather than simply fleeing. This study describes this behavior in goitered gazelles (Gazella subgutturosa) and examines its association with four recorded factors: approach category, group size, group composition, and month. In a forward stepwise logistic regression, approach category was associated with crossing behavior (Wald = 22.784, df = 2, p < 0.001). The odds of crossing were higher in the high-category group than in the low-category group (odds ratio = 2.36). However, the categories also differed in object type (cars, motor scooters, and bicycles/pedestrians), so the independent effect of speed cannot be separated from the effect of object type. Group size, group composition, and month did not meet the model’s entry criteria. These observational results identify an association, but do not determine whether path-crossing is a uniquely anti-predator response, a reaction to limited assessment time, or another form of behavior.
