A new paper in the journal Molecular Ecology describes how scientists at the Institute for Bird Populations joined a team of researchers to present a new analytical approach to studying migratory bird connectivity by integrating genetic and isotopic information into a single model.

Recent progress in studying migratory bird connectivity has been made using genetic and stable-isotope markers to assign migratory individuals to their breeding grounds. In a new paper in the journal Molecular Ecology, IBP scientists joined a team of researchers to present a new analytical approach integrating both types of information - genetic and isotopic - into a single model with more accuracy than either source of information alone can provide. As a sample application, we used samples collected at MAPS and MoSI stations to detect a subgroup of Wilson's Warblers wintering in Baja that uniquely migrate preferentially from the coastal Pacific Northwest (see Figure).
