"This study examines the Passeriforme (perching bird} population within the Sekulman wetland complex, located in the Yukon Plateau Mountain Range of south-western Yukon Territory. Field work was conducted from June 1 to July 4, 1996 under the supervision of David Mossop of Yukon College and the Renewable Resources Department of the Yukon Territorial Government. The study is intended as a contribution to the overall biological database being compiled by Mossop in his efforts to achieve a better understanding of the ecological systems at work in this wetland. Although the study concentrates on the Passeriforme population, all field observations have been included." (from Introduction)
