Jack, it is always like that, you rarely will shoot the same object in the same light. Here I will post few photos of my rarest bird - Leucistic Pacific Golden Plower. I choose this one because it is really exceptional (just search the net for such a Plower, at least last year there was no single shot available... There are many thousands of this bird around during the winter but leucistic - forget! The first photo was taken at ~12:00 p.m, thinly overcast day, slight adjustments to mach what I have seen. Four days later I went there to check on it (they are territorial and use to stay on the same place for long). It was ~7:30 in December morning and the sun was very low, no single cloud there. Completely different cast (tint, hue, temperature of the light). My first reaction was to change this to the "real" colors (and I have a variant like that). Returned back -
to save the spirit of that morning (and any way, I already had the real colors). And what actually are the real colors - the same bird has different tint/hue in different lighting conditions... For common birds I don't bother to think that much (but I may adjust the colors if I think the photo is good enough...). I like your photos as they are, you may decrease the blue with the RAW curves for the last two but be careful - you may sit in even deeper mud
