  1. Listed in the table are ID for each depredated carcass or nest, the total number of eggs collected from each nest (# eggs), the number of eggs with successful predator ID using DNA sequences (# successful sequences; CB cytochrome b, CR control region), # of microsatellite genotypes used for species idenitifcation (# msat genotypes for set A and set B), species identification using genotypes and assigned in STRUCTURE (STRUCTURE assignment), identification of predator based on sequences, microsatellites, or both (molecular ID), predator identification in the field from nest remains (Field cue), and predator identification based on trails cameras placed on nest. The percent match was generated from BLAST. WY Wyoming and WI Wisconsin
