Behavioral flexibility is considered important for a species to adapt to environmental change. Yet behavioral flexibility relates to problem solving ability and speed in unpredictable ways. This leaves an open question of whether behavioral flexibility instead varies with differences in individual behaviors, such as neophobia or exploration. If present, such correlations would mask which behavior causes individual variation. I investigated whether behavioral flexibility (reversal learning) performances were linked with other behaviors in great-tailed grackles, an invasive bird. I found that behavioral flexibility did not significantly correlate with neophobia, exploration, risk aversion, persistence, or motor diversity. This suggests that great-tailed grackle performance in behavioral flexibility tasks reflect a distinct source of individual variation. Maintaining multiple distinct sources of individual variation, and particularly variation in behavioral flexibility, may be a mechanism for this species’ invasion success by permitting populations to cope with the diversity of novel elements in their environments.
