John Speakman is a scientist from Scotland who studies how animals move and how their movements affect their survival. He has looked at how animals such as rats, deer, and songbirds find food, and how some animals can move quickly over short distances, like mosquitoes or bees. He has also studied how animals escape predators, which is important for their survival. In his research, he has discovered how animals can save energy while moving around. John Speakman's research helps us understand how animals live and move around in their natural habitats.
