I want a detailed explanation about how pigeons tell the difference between male and female.

First of all, look at the size, the same species of pigeons, male pigeons are often slightly larger than female pigeons.

Second, look at the walking posture. When the male pigeon walks, he often holds his head high. In order to stand out from the flock, he often overlooks, in order to find the danger as soon as possible. It's a bit like walking with a rooster, but the mother pigeon can't

The third one listens to the movement. After spring, adult male pigeons will be more active. They will always follow the female pigeons and make a loud "goo goo" sound. Although female pigeons can also make sounds, their voices are smaller than those of male pigeons. During the breeding season, unpaired male pigeons will constantly harass the female pigeons and easily conflict with other male pigeons.

Fourth, pigeons that have begun to hatch, the mother pigeons hold their nests at night, and the male pigeons keep watch. During the day, only at noon and afternoon, male pigeons will hatch eggs.
