Minnesota's State Bird - the Common Loon

The Common Loon - larger than a mallard but smaller than a goose, this water bird has a thick neck and a long, black bill. Its legs are set far back on its body, so it has an awkward gait on land. The male is slightly larger than the female, but otherwise the two sexes look identical.
Weight: Adult loons weigh 8 to 12 pounds.
Color: The common loon has a black bill and a red eye. In summer it is a spotty black and white with a black/iridescent green head. In fall a "winter coat" that's gray above and white below replaces its summer plumage.
Sounds: The common loon has four calls. The tremolo, which sounds a bit like maniacal laughter, is an aggressive call. The wail is a long, drawn-out sound. The hoot, a shorter call, is used to communicate among parents and young. The yodel is sounded by male loons guarding their territory.
Minnesota has more loons (roughly 12,000) than any other state except Alaska.

Fun facts to know about loons:

• Loons' lives are filled with fun facts. For example:
  The bones of most birds are hollow and light, but loons have solid bones.
• The extra weight helps them dive as deep as 250 feet to search for food. They can stay underwater for up to five minutes.
• Because their bodies are heavy relative to their wing size, loons need a 100- to 600-foot "runway" in order to take off from a lake.
• Loons can fly more than 75 miles per hour.
• The red in the loon's eye helps it to see under water.
• Scientists think loons can live for 30 years or more.
