What does a hummingbird look like? Have you got any pictures?

Hummingbirds usually have blue or green feathers, and their lower bodies are lighter. Some males have crests or slender tail feathers. Most males are blue-green, some are purple, red or yellow. The feathers on the female bird are dull. Hummingbirds have two subfamilies, cryptoptera and hummingbird. Hidden birds are generally brown, gray and red, without iridescence.

Hummingbird subfamily has rainbow-colored feathers with metallic luster of red, orange, blue and green. Iridescent is mainly concentrated in the head, upper body and lower body of male birds. Some males also have beautiful feathers, such as distinctive throat spots, crests and slender tail feathers.

Hummingbirds are hermaphroditic. Females are generally bigger than males, and males usually have more feathers and decorations. Female birds are likely to have more hidden colors than male birds, so it is not easy for female birds to attract natural enemies to their nests during incubation and brooding. The feathers of adult birds are similar to those of female birds.

Living habits

Hummingbirds can feed and nest in various land habitats. The main habitat choice is a large number of nectar-producing flowers, and the habitats that meet this condition are arid shrub jungle, desert oasis, coastal lowland, tropical rain forest, pine forest in New Taipei and alpine tundra.

Hummingbirds live in places with great differences in altitude, from the Andes as high as 4876 meters to the inland desert below sea level. Hummingbirds sometimes appear in cities and suburbs with natural food sources because of bird breeding and the rise of plantations.

Hummingbirds, like other birds, have no developed olfactory system and mainly rely on vision. Hummingbirds, unlike most vertebrates, are sensitive to ultraviolet light of 325-360 nanometers, which is convenient for them to find some flowers with ultraviolet spectrum. The feather color of male birds can be used by female birds and competitors of the same kind to evaluate their leadership and status and distinguish species.

Hummingbirds are solitary animals and only pair in the breeding season. Many kinds of male hummingbirds are territorial, centered on food sources and guarded by males. Male birds usually perch in a conspicuous position and look around. If an intruder invades the territory, the male bird will give a warning and hover in the air, flashing rainbow feathers, and will drive away the intruder if necessary. Occasionally, the conflict will escalate and turn into a fight with the mouth as a weapon.

When food is scarce, the Lord will reduce his efforts to drive away the invaders. Female birds will also establish territory around the nest. Hummingbirds without territory are mainly foragers. They travel on land and suck large flowers.

Male birds usually gather in ancient courtship places to show off their courtship behavior, and female birds will also come here to choose a mate. When courting, the male bird will perform wonderful flying skills in front of the female bird. The flying height can rise to more than 30 meters, then dive to the female bird, dive to the bottom and then float.

Hummingbirds spend 70% of their time resting because of their high metabolic rate and the consumption of active flight. Strong curiosity will drive them to take colorful objects as food to find out. Hummingbirds are diurnal birds, foraging during the day, and the peak of foraging is at dawn and dusk.
