What does the ability to switch between surface picking (grains) and deep probing (clams) demonstrate about the Whooping Crane?
Answer
Behavioral plasticity key to success as long-distance migrants
The Whooping Crane exhibits significant behavioral plasticity, which is defined by its flexibility in response to environmental cues and food availability. The capacity to fluidly shift foraging techniques—from quickly picking up surface items like spilled grain or berries to engaging in laborious deep probing to unearth buried clams or root vegetables—is central to its success. This adaptability ensures that the species can maintain necessary caloric intake while crossing vastly different terrains and encountering varied ecological conditions along the span of the North American flyway.
