MCQ Detailed View

The hummingbird is one of the smallest birds in the world and is famous for weighing less than a penny, typically around 2–4 grams depending on the species. Hummingbirds are native to the Americas and are well known for their ability to hover in mid-air, flapping their wings extremely fast — sometimes over 50 times per second.

These tiny birds feed mainly on nectar from flowers, but they also eat small insects and spiders to get protein. Their extremely light body allows them to perform agile flight maneuvers, hover at flowers, and migrate long distances despite their size.

Other small birds like the Goldcrest and Weebill are also very light, but the hummingbird is generally the lightest among the commonly cited species, which is why it is the correct answer.

Hummingbirds have very high metabolic rates because of their fast wing movement. They need to eat almost constantly throughout the day to maintain their energy levels. Their small size, lightweight skeleton, and rapid metabolism are all adaptations for survival and efficient flight.

Understanding the hummingbird’s tiny size and unique adaptations is part of biology, particularly in zoology, animal physiology, and bird studies. It helps students learn about energy requirements, feeding habits, and survival strategies in small animals.

In short, the hummingbird is the bird that weighs less than a penny, demonstrating the amazing diversity and specialization of birds in the natural world.
