The extraordinarily powerful wings and torso of the Mute Swan
The above photo is a lucky capture as I was actually filming the Gadwalls behind the swan. When the swan began to lift out of the water I quickly turned my attention toward it. The first two photos are the same; the first is cropped, the second uncropped so that you can see the tremendous scale of the swan’s body and wings in relation to its environment. The Mute Swan is the second heaviest waterfowl, second only to the Trumpeter Swan. In observing swans, I marvel in nature that a creature this heavy can soar majestically through the clouds and swim so gracefully through water.
Mute swans feed primarily on submerged and emergent aquatic vegetation and a small percentage of their diet also includes frogs, small fish, and insects. Because swans feed in deep water they do not compete with smaller waterfowl such as ducks. It is thought that food is made more readily available to ducks because the swans do not eat all the food they pull up. This seems logical and factual from my own observations at our local ponds and marshes. I very often see a wide range of waterfowl congenially feeding with the Mute Swans.

Note ~ Mute swans, which are a nonnative species, do compete directly for food with North American native Trumpeter Swans, in regions where Trumpeter Swans are indigenous (Trumpeter Swans are not native to Cape Ann).
