The Columbia Region Ecological Discussions include speakers addressing a diversity of topics such as science communication, active ecological management, citizen science, research skills and techniques and the influences that our natural environment has on art and culture. Presentations will be recorded and available online through the Columbia Mountains Institute of Applied Ecology website.
Yellow Warbler is a small passerine that visits British Columbia annually for about three months of the year. A small breeding population of these warblers which nest in the drawdown zone of Arrow Lake reservoir near Revelstoke has been monitored since 2004. While a lot of information has been acquired about their local breeding ecology, relatively little is known about how these birds survive the remaining 9 months of the year. As long-distance migrants, they face many challenges on both their breeding and wintering grounds, as well as during migration. In this talk, Michal will present part of his PhD thesis and talk about the annual and seasonal survival of Yellow Warbler with a focus on identifying stages of the annual cycle when mortality of these birds is the highest.
