       White, sometimes black, and always beautiful--Cygnus Atratus, the scientific name--is better known as the swan. Swans can make a heart with their necks when they kiss, and they mate for life;  no matter what, they stick together.

     Related to geese and ducks, there are over 25,000 swans, and they come in different variations such as a black-necked swan, a black swan, whooper swans, tundra swans and even mute-swans. They are highly intelligent, and another unique feature is that they only swim with one leg.

        As peaceful as they may seem, they can get very grumpy so don't ever threaten them. They've attacked dogs, kids and other birds, just to protect their eggs. Swans can even be dangerous for humans causing injuries because they may even bite. However, swans are actually herbivores that dive to the bottom of ponds, lakes and river. 

      Swans weigh up to 30 pounds and are the largest bird to fly at 60 miles per hour. These majestic birds live everywhere but Africa and South America.
