"Goose swan is not a friend?"

On weekends they went to the zoo with their children.

There is always a crowd around this pond. Those who want to admire the most beautiful bird are full. As you guessed it, these are swans.

At a small bridge, they probably are fed up in secret. A pair of white winged handsome men does not leave anywhere. Trustfully reaching out to the hands of visitors. They can "chew" the toe of the shoe, pushed by someone through the bars of the railing. And, sometimes and tangibly bite, because inside of the beak of the swan there are denticles at the edges.
Knowingly knowing that the swan-swans live there, at first did not notice that these differ slightly from each other.

Not immediately noticed that their beaks are different. So, the mute and the klikun formed a pair? The klikun has a beak, look, lemon yellow with a black tip. I did not know that such an alliance was possible.

Next to the swans is a bird similar to them, but a gray bird. Maybe it's their grown-up cub in a teenage pore of an ugly duckling?

Already at home, processing pictures, I found in the internet that this is a chicken goose. That's how the company turns out! Not only the miter and the goose, but the goose live together. And, it seems, they are friends.
