Hummingbird hovering flower

Hummingbirds are unique birds capable of hovering flight, feeding on flower nectar and playing a crucial role in pollinating various plant species across the Americas.

About this subject

Hummingbirds belong to the family Trochilidae, which is exclusive to the Americas and comprises over 300 described species. Brazil hosts about 80 of these species, ranking among the countries with the highest diversity of these birds. Their ability to hover is due to wings that beat 50 to 80 times per second, allowing precise forward, backward, and even upside-down flight.

They primarily feed on nectar, using a long, forked tongue that rolls up to lap the liquid. While visiting flowers, pollen adheres to their head and bill, then is carried to other plants, making them key pollinators for species such as trumpet vines, bromeliads, and passionflowers. Unlike bees, they can pollinate deep tubular flowers.

Some species undertake remarkable migrations, like the Ruby-throated Hummingbird (Archilochus colubris), which travels from Canada to Mexico each year. Their metabolism is extremely fast: they consume up to twice their body weight in nectar daily. To conserve energy at night, they enter a torpor state, lowering body temperature and heart rate.

Conservation challenges include habitat loss and pesticide use. Gardens with native flowers such as lantana and sage help attract and support them. Watching a hummingbird hover near a flower is a natural spectacle shaped by millions of years of evolution.

Frequently Asked Questions

Why can hummingbirds hover in place?

Their wings move in a figure-eight pattern, generating lift on both the upstroke and downstroke. This allows them to hover, as well as fly forward, backward, and sideways.

How many species of hummingbirds are there?

There are over 300 species of hummingbirds, all native to the Americas. Brazil hosts about 80 of them, making it one of the most diverse countries for these birds.

How can I attract hummingbirds to my garden?

Plant tubular flowers in bright colors, especially red and orange, such as trumpet vine, sage, and fuchsia. Avoid pesticides and provide fresh water in misters or specialized feeders.
