No, a harpy eagle is not a mammal; it is a bird of prey. Specifically, the harpy eagle belongs to the family Accipitridae and is one of the largest and most powerful eagles in the world.
Mammals are characterized by features such as having fur or hair, being warm-blooded, and most notably, females possess mammary glands that produce milk for their young. In contrast, birds have feathers, lay eggs, and have beaks instead of teeth. The harpy eagle, like all birds, has these avian characteristics.
Harpy eagles are predominantly found in tropical rainforests in Central and South America. They are known for their impressive size, unique appearance, and powerful hunting abilities. Their diet mainly consists of medium-sized mammals and birds, which they hunt with incredible strength and skill.
