Behavior is the secret to success for a range expansion

Researchers find that behavioral flexibility and persistence help species, like the great-tailed grackle, expand their range and adapt to new habitats

While many species are undergoing drastic declines in their numbers and geographic ranges, other species seem to be thriving. Researchers investigating the great-tailed grackle, a bird that has been establishing new populations across North America in the past few decades, reveal that behavior might play a key role in their success. They found that the population on the range’s edge is more persistent and has more variability in flexibility, and that this species has shifted toward living more in urban, arid environments.
