seasonal patterns in δ(2) h values of multiple tissues from andean birds provide insights into elevational migration.elevational migration is a widespread phenomenon in tropical avifauna but it is difficult to identify using traditional approaches. hydrogen isotope (δ(2) h) values of precipitation decrease with elevation so δ(2) h analysis of multiple bird tissues with different isotopic incorporation rates may be a reliable method for characterizing seasonal elevational migration. here we compare δ(2) h values in metabolically inert (feathers and claws) and metabolically active (whole blood) tissues to examin ...201627907263
