The Common Loon
Scientific name: Gavia immer
Migration
The length of their migration can be between 1,600 miles to 2,800 miles.
Sound
The sound of the common loon is so loud it can be heard from one mile away.
Bones
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.
