Genetic variation describes naturally occurring genetic differences among individuals of the same species. This variation permits the flexibility and survival of a population in the face of changing environmental circumstances. What is an innate behavior some birds display in response to shortening day length, drop in temperature, or the beginning of winter?

Answer 1

An innate behavior that some birds display in response to shortening day length, drop in temperature, or the beginning of winter is migration. Many bird species instinctively migrate to warmer regions during the winter months to find food and more favorable living conditions. This behavior is often triggered by changes in daylight and temperature, and it is an essential survival strategy that allows birds to adapt to seasonal changes in their environment.
