  1. The mass listed is the observed mass [M+H]+ from the MALDI TOF mass spectrometry of the HVC samples. The peptide identities of 13 peaks in the mass spectrum of the HVC homogenate were assigned based on mass matches to the previously identified peptides. Three peaks (877.4, 1375.9, and 1415.8 m/z) were assigned to two putative peptides each. A check mark (√) indicates the song nucleus where the masses were observed. A dash (-) indicates it was not detected.
