Japanese quail is a small relative of chickens and turkeys with very rare properties. Men produce unique, ingenious forms similar to meringues.
While bubbles are rare among birds, turkeys produce similar substances.
Japanese quail was raised as early as the 11th century, and was initially kept for melodic songs. However, they were later exploited for meat and eggs.

Small birds weighing 3.5-10.5 ounces (100-300 grams) reach sexual maturation for about six weeks, and women are prolific egg layers, producing 250-300 per year. For this reason, they are also very popular in scientific research. And in 1990 they became the first birds to incubate and hatch in space.
Scientists first noticed in the 1950s that Japanese quail had unusual foamy semen. It has been the subject of research ever since. Their unique psychological bubbles are produced during mating by the bone marrow glands of the cloaca, a cavity containing both excretion and reproductive organs, and are thought to increase the chances of successful fertilization of female eggs.
The bubbles combine semen with the sperm itself upon ejaculation. That hilarious consistency is created by the contraction of muscles within the cloaca, amplifying the effects of gases released by microorganisms within the cavity.
The foam is thought to help sperm cells mature after they enter the female genital tract and are stored for 8-11 days before fertilization occurs. It also increases sperm motility and protects against bacteria.
After successful insemination, the man does a little strut.
