1) Eastern Black kingsnake(Lampropeltis getula nigra)with some possible Speckled kingsnake(L.g.holbrooki) geneflow eating a Copperhead(Agkistrodon contortrix ssp.)
2) Looks to be a Regal Ringneck(Diadophis punctatus regalis) consuming a California Mountain kingsnake(Lampropeltis zonata ssp.)
3) Banded Desert phase California kingsnake(Lampropeltis getula californiae) that consumed another California Mountain king(L.zonata ssp.) tough to tell exactly which subspecies though since the head isn't visible in either of the photos.
