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, bellshaped flowers is introduced to the region, resulting in fewer shortbeaked and more longbeaked hummingbirds. Which of the following conditions most likely caused this shift in the hummingbird population?
