A population of hummingbirds is composed of individuals with short or long beaks, which they use to reach nectar inside flowers. A flowering trumpet vine that produces many deep, bell-shaped flowers is introduced to the region, resulting in fewer short-beaked and more long-beaked hummingbirds. Which of the following conditions most likely caused this shift in the hummingbird population?
