How do birds reproduce?

Question

Do they do it sexually?

They p.i.s.s comes out with their poo so do they reproduce like humans?

Answer 1

Hormones from the pituitary gland are the answer. During breeding season in response to the hormones, the male's testes become several hundred times larger than normal to produce sperm, with the left testis usually larger. The female bird's ovaries also enlarge during breeding season to produce the ovum. Female birds usually only have one functional ovary, the left one.

In birds, an ovum is fertilized in the female bird's oviduct by a sperm cell from the male bird. Once fertilized, the ovum becomes the nucleus of the egg. The egg, that has its own food source, the yolk, will be laid by the female into her nest, incubated, and then the baby bird will hatch.

But how does the sperm from the male bird get into the female? How can they have intercourse without any external male organs, such as a penis? The male's sperm, produced in the testes, passes to the cloaca where it is stored until copulation (act of sex). The female also has a cloaca that leads from the ovaries. The female bird unfans her tail, moves it to one side while the male climbs up onto her back or gets close to her. Their cloacas are pressed together and the sperm moves from the male to the female. This act is called a cloacal kiss. Click here for a diagram of the male and female bird sex (reproductive) organs.

The sperm is stored by the female for at least a week, in some species over a hundred days. Then as each ovum from the ovary moves into the oviduct, it gets fertilized with the stored sperm, producing a clutch of many eggs, all with the sperm from that one cloacal kiss.

There are a few species of birds where the males do possess a retractable penis that can be pulled back into the bird. These birds include ostriches, cassowaries, kiwis, swans, geese, and ducks. Since waterfowl sometimes make love while in the lake or pond, the penis helps ensure that the sperm is not washed away by the water.

Sperm can be transferred from male cloaca to the female in a blink of an eye - less than a second. Some birds seem to want to linger longer though, sometimes having sex for more than an hour! And, although it is not necessary to copulate frequently since the sperm is stored within the female, remember those hormones are still making the birds excited. Many pairs of birds will mate numerous times within a few days.

Answer 2

Birds are quite variable in their behaviors. Bird reproduction varies quite widely from one family to another. In general, the male first claims a territory. Then he tries to attract a female through a ritualized courtship display, which could include one or more of: a song, building a nest, posing, or bringing a piece of food. Some species engage in an elaborate courtship ritual, while others have very litltle in the way of courtship. The female may accept or reject the male's advances. If she accepts, they copulate, usually by rubbing cloacas together. The cloaca is the terminus of both the digestive system and the reproductive system. During copulation, the male transfers sperm to the female, to fertilize her eggs. After the eggs have developed, the female lays the eggs in a nest. Laying may take place over several days. After all eggs are laid, incubation begins. Incubation may be by the female or the male, or by both. When the chicks hatch, they may be helpless or quite developed and able to largely fend for themselves. In the former case, the female, and sometimes the male bring food for the chicks until they fledge and are able to leave the nest. It must be emphasized that birds are quite variable in all aspects of their lives, including in their reproductive behavior. Perhaps you can find some suitable material in your high school library and/or get some advice from a biology teacher to help with your project. Good luck!

Answer 3

The male and female both have a cloaca, an opening that functions both for excretion and reproduction. The male and female push their cloacas together in what is called a "cloacal kiss" and the sperm is passed from the male into the female. Some birds..such as male waterfowl (ducks, swans, etc) and ostriches have a penis.

Answer 4

Most male birds don't have a penis and only internal reproductive organs.

The male will get on the female's back and their cloacas meet to pass sperm.

Answer 5

ohhhh your not thinking of getting dressed up in a bird costume are you and having some kind of kinky sex,ah well whatever turns you on i suppose

Answer 6

lol, yes they do it sexually. It sucks for the female though---the male usually digs his claws into her back.

Here's a video in case you're reeeally curious and can't wrap your mind around it.
