#6 Tundra Swan vs. #11 Yellow-crowned Night-Heron

Tundra Swan

  • The whistling swan is the American version of the Tundra Swan.
  • While the Tundra Swan sleeps on the water during the winter, it spends the breeding season sleeping on land.
  • Tundra Swans will defend their nests against foxes, weasels, and gulls but will leave the nest quickly when bigger predators approach such as wolves, people, and bears. They do this to make their nests harder to find for predators that they cannot fend off.
  • Tundra Swans stay in flocks whenever they are not on their breeding grounds.
  • The roundtrip migration for Tundra swans covers 3,725 miles.

The reason we haven't posted photos is because we do not have photos of most of the birds on our bird poll. We will see what we can do to find some free images to use for the future and current bird polls. Thanks for the feedback.
