I had to jump in here.
First: no doubt in most areas excluding the sandhill country in SE GA and central FL that the kingsnakes avoid like some kind of cursed region of the giant black snakes...knigs are doing much better and populations healthier.
Consider this theory though: the eastern indigo is a tropical snake managing to squeak out a living in a region that gets pretty cold. This genus developed in the tropics. Their cousins (cribos) are doing quite well.
Indigos are like an island animal almost...they manage to hold on because of the deep burrows and the warm sun that pokes it's way through occsionally even in the winter. When it's 50 degrees and sunny in December and the kings are deep in the winter slumber, indigos are out basking.
They are out of the genus' true element and are therefore restricted to a very limited habitat, especially in the winter.
Add to this the fact that they eat so much...the populations even when healthy are not meant to be large.
They are like the elusive jaguar in the jungles of SA as compared to the more numerous smaller predators.
Imagine this: A population of getula from Georgia somehow made it to some island that is hot, dry desert, but has a mountain range that is lush and tropical. The GA kingsnakes can't handle the heat and no humidity of the desert part of the island, but a few managed to find the mountain range. It was not perfect habitat, but they managed to make do, and adapt to the conditions. Over time, they reproduced and became ingrained as a part of ecosystem.
Now...suddenly, the mountain range is being deforested and fragmented with roads and buildings / homes etc. The numbers of the kings in those areas are getting alamingly low as people kill them, collect them, and they get run over.
They have no where else to go.
This is the state the eastern indigo is in.
Not a weak species by any stretch, when you think in these terms.
