SPECIAL PUBLICATION of the WATERBIRD SOCIETY The Waterbird Society announces the publication of a special volume on the conservation issues facing members of the Loon Family (Gaviidae) with an emphasis on the Common Loon (Gavia mimer), but including papers on Red-throated Loons (Gavia stellata) and Yellow-billed Loons (Gavia adamsii). The Loon Research and Conservation in North America Special Issue of Waterbirds is a series of technical, peer-reviewed papers commonly related to loon biology and conservation, that represent the proceedings of the workshop The Status of Gavia: Conservation in Black and White held August 14, 2012, at the University of British Columbia as part of the 5th North American Ornithological Conference. This special issue presents 15 papers (listed below) that further our understanding of Gavia behavior, life-history and population ecology, movements and migrations, habitat and landscape requirements and the impacts contaminants have had on loon populations. ****************************************** Loon Research and Conservation in North America Preface to the Loon Workshop Proceedings, North American Ornithological Conference, University of British Columbia, 14 August 2012.
