Recognizable for its eerie calls and striking black-and-white coloring, the loon resides on many New Hampshire lakes but is threatened by the gradual loss of its habitat. Two trails wind through the 200-acre Loon Center; vantage points on the Loon Nest Trail overlook the spot resident loons sometimes occupy in late spring and summer.
