Description of call: 'peep... peep... peep..'

Northern spring peeper Pseudacris crucifer crucifer
This tree frog is widely distributed on Isle Royale. Spring peepers are found in temporary woodland pools formed by rain and melting snow in early spring. Adults wonder far from water in summer, but are seldom seen because their activity is nocturnal and they tend to stay in shady, shrubby cover. Outside the breeding season they forage in woodlands or amongst shrubs and marshes bordering woodlands. In March, April and May, large choruses of their "peep... peep... peep..." calls are heard from woodland pools.		Park Status	Present in Park
