“Since 1998, CMMN stations participated in several broad-scale collaborative research studies that increased our understanding of migratory bird stop-over ecology (e.g., Dunn 2001, Dunn 2002), examined the effect of climate change on the seasonal timing of migration and stop-over site quality (Marra et al. 2005), assessed the role of migratory birds in the spread of diseases affecting wildlife and humans (e.g., Ogden et al. 2008a, Ogden et al. 2008b), and contributed to a large-scale DNA ‘barcoding’ project. In 2007, following on the work of Dunn et al. (2006), CMMN stations across Canada collected over 18,000 feathers from 22 species in an extensive collaborative research project that is presently underway on feather isotope signatures, which will further our understanding of the geographic origin of birds passing through each station. Information from this particular project will help interpret population trend results and can more clearly define geographic areas in need of conservation measures.” Crewe et al, 2008.
