Are there hummingbirds in China?
Bird country on the equator
Ecuador, located on the equator, is a small country with amazing biodiversity, and its birds, especially the hummingbirds in the Andes, are even more colorful.
Extended information Hummingbirds can fly backwards.
Hummingbird's shoulder joint is very flexible, and its wings can rotate to the maximum extent, making it fly backwards and take off and land vertically. Moreover, hummingbirds' pectoral muscles account for a larger proportion of their bodies than other birds, so they have a strong ability to vibrate their wings.
Hummingbirds are still flying up and down even when they are sucking nectar. Their bodies remain vertical, and their wings vibrate back and forth instead of up and down. The airflow generated by the vibration will safely lift the hummingbird's body. Coupled with the small weight of hummingbirds, the rising force of air is also small, and the air resistance encountered is not great. Its flexible wings allow it to twist at a large angle when flying, and its flexible tail can also control the direction of lift. Coupled with the support of high-frequency vibrating wings, it is enough for them to fly freely.
