The average flapping amplitude of hummingbirds is only 50-80 times per second, which is much lower than the flapping amplitude of horned hummingbirds of 90 times per second. Horned hummingbirds mainly feed on nectar, so they need to flap their wings at high speed to achieve long-term hovering and horizontal flight.
Horned hummingbirds, like most hummingbirds, are very colorful. Just above their heads, there are blue, red and green feathers, while the whole head is dark blue, the body is yellow-green, the abdomen is white, the wings are light brown, and the tail is dovetail-shaped V-shaped. Relatively speaking, females are much darker in color and have no male crown.
Horned hummingbirds mainly live in grasslands and woodlands, and are often seen in Brazil. They mainly feed on nectar from shrubs and trees, and also prey on small insects.
The global population is not quantified, but it belongs to rare species in origin and is easy to adapt to artificial habitats, such as gardens and other artificial breeding areas, so it is speculated that its population may be in a state of growth.
Breeding methods of horned hummingbirds:
The bird's nest is usually built on a bush branch 1 m above the ground, which is cup-shaped and made of soft plant fibers and spider silk. Two eggs are laid in a nest, and the mother hatches the eggs alone. The incubation period is about 13 days. Young birds grow feathers 20~23 days after birth and can reproduce in the second year of adulthood.
