Question

the reproduction in birds with diagram?? specially in pigeon ​

Answer 1

We know that chickens lay eggs. But how do they do that?

It all starts with behavior aimed at attracting a mate. In birds, this will involve a type of display, usually performed by the male. Some displays are very elaborate and may include dancing, aerial flights, or wing or tail drumming. Most male birds also sing a type of song to attract females. If they are successful at attracting a female, it will lead to breeding.

Answer 2

Answer:

The sexes are separate. Sexual dimor­phism is absent in pigeon

The female reproductive system is pecu­liar by having only left ovary and left oviduct.

Piegon:

Pigeons are some of the most visible birds on earth. They are often seen wandering cities with their stubby necks reaching out for food. Some pigeons, like the feral rock pigeon, weigh only a pound or two. Other pigeons, such as the crowned pigeons in New Guinea, can reach almost 10 pounds. Both male and female pigeons have sex organs that play a role in reproduction.

Pigeons are monogamous and typically mate for life. Female pigeons can reach sexual maturity as early as 7 months of age. ... Eight to 12 days after mating, the females lay 1 to 3 (usually 2) white eggs which hatch after 18 days.

The female moves her tail to the side and the male gets behind her. Both pigeons have small protrusions known as "cocacal protuberances." The pigeons touch each other's protrusions and insemination occurs quickly. The male pigeon ejaculates within a half second after mounting and touching the female pigeon, and his sperm enters her reproductive tract.

Most male birds, including pigeons, have no external sex organs. The male pigeon has two interior testes that swell during the breeding season and produce sperm. Adult female pigeons have only one ovary, although two are present in their embryonic stage.

The egg travels through the female reproductive track, gaining substance and nutrients and the shell is formed. The egg is then stored in the female's uterus until it is laid. Two eggs are often produced and laid within twenty-four hours of one another.
