Discover the Dazzling Hummingbirds of South America

The Allure of Hummingbirds

Hummingbirds, belonging to the family Trochilidae, are renowned for their rapid wing flaps, which can reach up to 90 beats per second, creating a distinctive humming sound. This sound varies across species due to differences in wing flap frequencies. Typically, hummingbirds range in size from 7 to 13 cm. The Bee Hummingbird (Mellisuga helenae), the tiniest among them, measures merely 5-6 cm, whereas the Giant Hummingbird (Patagona gigas) stands out at about 23 cm.

Habitats and Migration

These vibrant birds are found from southeastern Alaska all the way to Chile, thriving in diverse environments across the Western Hemisphere. While most hummingbird species are non-migratory, some are known for their impressive migratory journeys, covering distances over 2,000 miles biannually.

Diet and Feeding Habits

Hummingbirds consume up to twice their body weight daily to support their high energy expenditure. They primarily feed on nectar, using their long, tapered bills to access it and their specially adapted tongues to lap it up. Contrary to popular belief, they do not suck nectar through their beaks like a straw. Besides nectar, these birds also consume insects, pollen, and tree sap, visiting up to 1,000 flowers each day.

Key Facts About Hummingbirds

• Physical Features: Their tiny feet are used only for perching, and they have the ability to conceal their iridescent feathers.
• Sensory Abilities: Hummingbirds possess excellent hearing and vision but lack a sense of smell.

• Territorial Nature: They are highly territorial, often chasing away much larger birds.
• Speed and Rest: They can fly at speeds up to 55 kph and enter a torpor state for rest, significantly lowering their body temperature and metabolic rate.
