Multiple methods of diet assessment reveal differences in Atlantic puffin adult and chick diets both between and within years

The paper compares diet assessment methods in Atlantic puffins, finding similar prey composition but differences in species diversity and taxonomic resolution between traditional and DNA metabarcoding approaches.

From presence/absence to reliable prey proportions: A field test of dietary DNA for characterizing seabird diets

This study demonstrates that dietary DNA can quantitatively estimate fish proportions in seabird diets, showing high correlation with biomass observations and outperforming presence/absence metrics.
