Few animals evoke the feeling of the North Woods like the common loon (Gavia immer). This iconic symbol of Voyageurs leaves a lasting impression on visitors who hear its eerie yodel echoing across the lake. It is fitting for the common loon to be the state bird of Minnesota, as it supports the largest loon population in the lower 48 states. Where can you view loons? Visitors wanting a view of this beautiful bird will not need to search far. Loons are numerous throughout the park and are usually found floating in the deep water of the four large lakes.
