The Grants have studied finches on the Galapagos Islands for 40+ years. During times of drought, there is less green/flowering vegetation available as a food source for the finches. This leaves only the hard, thorny seeds. The Grants have found that during drought, finches with larger beaks survive at a higher rate because they can access the food source. This would be an example of

Ecological adaptations

An ecological adaptation is any morphological, physiological, or behavioral trait of an organism that allows it to survive and reproduce in a habitat or ecosystem. Adaptation is a biological mechanism by which an organism gradually gets more acclimated to its surroundings.
