Birds that can change their behavior in response to environmental conditions have better odds of survival than those that can't, and extinction risk is inversely linked to the number of new behaviors adopted, researchers reported in Nature Ecology & Evolution. However, behavioral plasticity protects birds only from habitat changes and not from excessive hunting or invasive species, and "the species with the greatest capacity for innovation have longer generation times, which makes them more vulnerable to hunting," said study co-author Daniel Sol.
