Riverine Birds

Common Mergansers Monitoring abundance and productivity of a set of target riverine birds assesses progress toward enhancing their quality and quantity of habitat. In 2009, Eight years of river-float surveys were analyzed to identify trends in abundance for nine species. Significant trends include: declines in Common Merganser abundance during the breeding season and during the fall; declines in Belted Kingfishers during the breeding season; and increases in American Dippers and Green Herons during the breeding season. Trends for all species are being further analyzed.
