What avian species has an adult weight lighter than a standard coin?
Show answer Hide answer
Answer: C. Hummingbird
Explanation
Hummingbirds possess exceptionally tiny physical bodies whose adult weight is less than a standard coin. The bee hummingbird specifically holds the record for being the smallest bird species known to science. This remarkable weight allows them to achieve their unique hovering flight mechanics with rapid wingbeats. Birds are warm blooded vertebrate animals characterized by feathers wings and lightweight hollow skeletal structures. High metabolic rates are required to power the intense muscle activity involved in hummingbird flight. These birds feed primarily on floral nectar using specialized long tongues and hovering maneuvers.
Hummingbirds serve as important pollinators for many species of flowering plants within their natural habitats. Their incredible flight agility and hovering capabilities fascinate biologists and nature enthusiasts worldwide. Protecting natural floral habitats is crucial for the survival of these tiny migratory bird species. Goldcrests are very small European birds but are noticeably heavier than the smallest hummingbirds. Weebills are among the smallest Australian birds but still exceed the weight of a coin. None of these is incorrect because hummingbirds correctly meet the criteria for this lightweight avian species.
