Yes, there are several. Some varieties of swan can weigh upwards of 50 lbs (which is a lot of bird), and they are extremely territorial, especially during nesting season.
They are known to kill other swans, as well as ducks or geese that get too close to their nest. There have been any number of dogs killed when they get too close to a nest. They are also known to attack canoeists, people in rowboats, and even jet-skiers.
Not just broken bones, but actual fatalities have occurred due to swan attacks. When they attack, they generally try to force their target under water, and in this manner they have killed a few children, and are suspected in the drowning death of a fisherman in Michigan a few years ago.
The truth is, swans actually kill more people than sharks every year, but for some reason don't get the same kind of bad press that sharks, or almost completely harmless creatures like spiders or bats do.
