Hummingbirds – Small in size, vibrant in color, and exhibiting rainbow or metallic sheen.
Hummingbirds are the smallest birds in the world, and the largest giant hummingbird is no more than 20 cm, the smallest is only 5.5 cm, and 2 grams. Hummingbirds have a long, straw-like beak used to feed on nectar.
Hummingbirds, due to the buzzing sound produced by the vibration of their wings during flight, are named after bees. Hummingbirds belong to the animal kingdom, the hummingbird family, with 104 genera and 355 species.
Hummingbirds' flight is very peculiar, not only good at hovering in flowerbeds for a long time, but also the only birds that can fly backward.
The hummingbird's tiny muscles can flap its wings 80 times per second. Its flight speed can reach 50 km per hour. They have no developed sense of smell and rely primarily on vision.
Figure 1 and Figure 1 are both Resplendent Hummingbirds.
Hummingbirds are distributed in Latin America, extending north to southern North America and along the east coast of the Pacific to Alaska. Due to their small size, it is difficult to preserve fossils, and their evolutionary history is still a mystery today.
