Information about hummingbirds

Hummingbirds have blue or green feathers and a light lower body. 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, cryptohuminae and humminginae. 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, and some males also have beautiful feathers such as bright throat spots, feather crowns and slender tail feathers. ? Female birds are generally larger than male birds, and male birds usually have more feathers and decorations.

Extended data:

Hummingbirds breed during the nectar-rich period. Each nest lays 2 eggs, which are white oval with dull surface. Because some hummingbirds lay eggs in other nests, there will be more than two eggs in each nest, and the interval between laying eggs is 48 hours.

The size of eggs ranges from 8× 1 1 mm of bees to12× 20mm of giant hummingbirds, with an average weight of 0.4-1.4g. The incubation period is usually 16- 19 days. The brooding period is 23-26 days.

Newborn chicks develop late and have no hair, so they can't open their eyes to regulate their body temperature. Female birds are fed nectar and arthropods twice an hour, and the chicks can control their body temperature after about 7- 12 days of feeding. When chicks are plump enough to leave the nest, they are still fed by females 18-25 days.
