A GEOGRAPHIC-INFORMATION-SYSTEM APPROACH TO ESTIMATING THE ORIGIN OF MIGRATORY RAPTORS IN NORTH AMERICA USING STABLE HYDROGEN ISOTOPE RATIOS IN FEATHERS

Analysis of stable hydrogen isotope ratios in feathers (δDf) is a promising method for investigating population connectivity in migratory birds. Stable hydrogen isotope ratios in precipitation (δDp) vary across North America with respect to latitude, elevation, and seasonal air-mass trajectories. A...
