1. The term used to describe birds flying south for the winter is "migration." Migration is a natural behavior in which birds travel to warmer regions during the winter months to find food, escape harsh weather conditions, and ensure their survival.
2. Fruit-eating birds have an ecological impact. The droppings of fruit-eating birds contain seeds that can be dispersed over great distances. This process helps in seed dispersal and contributes to the growth and diversity of plant species in different ecosystems.
3. Bird bones have a unique feature that allows them to reduce weight and make flight possible. Birds have hollow bones that are lightweight yet strong, providing structural support for flight. The hollow nature of their bones decreases overall body weight, making it easier for birds to stay aloft and maneuver in the air. This adaptation is crucial for the aerodynamics and agility required for bird flight.
