No, not all black swans belong to the Queen. In the UK, the crown technically owns all unmarked mute swans on open waters, but black swans are not included in this tradition. Black swans are native to Australia and New Zealand, and while they can be found in the UK, they are privately owned or belong to various institutions, not the monarchy.
There are many kinds of water birds; salt water and fresh water. Many are ducks and gulls. There are also Penguins, terns and boobies. Herons/cranes and pelicans also classify. Loons and cormorants are water birds. There are hundreds of water bird species around the world, and it's wonderful to read about them all.
