In Cincinnati we have Mute Swans on some of our ponds and lakes, which are also beautiful, but not native, so I was really excited to see these huge native swans in the wild! Trumpeter Swans are the largest waterfowl in North America and create quite an impressive sight. In the early 1900s Trumpeters were almost hunted to extinction. Their feathers, skins, meat and eggs were in demand, and hunting coupled with habitat destruction nearly wiped them out. Through habitat restoration, protection and reintroduction, Trumpeter Swans have survived and are now making a comeback!

How to tell the difference between a Trumpeter Swan, a Tundra Swan, and a Mute Swan...
Three species of swans live in North America: the Trumpeter Swan (the largest swan), the Tundra Swan (the smallest of the three), and the Mute Swan. The Trumpeter Swan and the Tundra Swan are native. The Mute Swan is an exotic, invasive Eurasian species introduced in the late 1800s as a decorative pond species. Originally, owners kept their wings clipped to keep them on their ponds, but over time, several escaped and now breed in feral populations. Mute Swans are easy to identify. They have large orange bills with a black knob. It's a little harder to tell Trumpeter and Tundra Swans apart since they both have black bills, but there are specific field marks that help you ID the birds. Here are a few sites to help you learn the differences:
Click here for a guide from the Kellogg Bird Sanctuary that explains how to tell the swans apart. It even has a little interactive test to help you learn the differences.
Click here for swan identification tips from the Trumpeter Swan Society.
Click here for a 6-page printable pdf that explains how to spot the field marks that differentiate swans and geese.
|If you read any of the ID tips on the links above, you learned Trumpeter Swans are often described as wearing "lipstick." If you look closely, you can see that field mark in this photo. (Again...photo credit to my cousin, Curg.)|

Trumpeter Swans are making a comeback in Ohio, but they are not safe yet...
The exotic Eurasian Mute Swans populating many of the lakes and ponds in Ohio are very aggressive and can outcompete Trumpeter Swans trying to establish a territory. They also are voracious eaters and can deplete aquatic vegetation for native waterfowl and even destroy entire wetland ecosystems, further squeezing out Trumpeter Swans.
Click here for a post titled "Swan Song," by John Windau on the Wild Ohio Education blog that explains in more detail the Trumpeter's plight and the steps taken to reintroduce them to Ohio.

Migrating Tundra Swans at Maumee Bay...
We also saw a small flock of migrating Tundra Swans on the inland lake as well. They were off in the distance and didn't stay long. It was an impressive sight to watch them take off together to move on to another lake.
