PROTECTION STATUS: Not listed
RANGE: Breeds in the high peaks of New England and northern Nova Scotia; winters in the Greater Antilles
THREATS: Climate change, pollution, logging, recreation- and telecommunications-related development, wind-energy projects
POPULATION TREND: Because of this species' unusual and complex mating system and the dense, often inaccessible habitat it prefers, estimating its global population size is difficult. However, studies of individual populations have consistently shown decline in the past 10 to 15 years.
