Syspila(red milks) can be extremely variable, and so can the Central Plains milksnake (gentilis). When a very specific ID is needed, it helps IMMENSELY to know what area of which state they were found in. This is because of range overlap intergrade zones that can have other geneflow from other neighboring subspecies affecting their outward looking phenotype(visual look).
They both look like Red milks to me, and the entire body and head on the second one isn't totally visible either, but could easily have some gentilis influence too depending on where it was found. The bottom one is absolutely NOT a rat x milk hybrid whatsoever, it is 100% milksnake.
congrats on the excellent finds!
