First off, them eating mice was not the question. The question would be more accurately A wild coachwhip taking food from a humans hands. Which I will tell you is not common with free ranging coachwhips. In most cases, they are GONE within seconds and you would not have time to feed them.
So why does four seperate individuals take mice from my hands. Sir, that is a good question. Not a simple, oh they eat mice type question.
I am very surprised at your next paragraph. Well not really, if your only trying to make trouble then it fits you. But if your serious, your not using what you have learned.
A prey base does indeed control population density, just not in ten days. As that is how long I have been feeding them. So its not going to increase or maintain a higher population in that time. Either your being silly again, or your not thinking this throught at all.
Again its really about better questions. A better question is, were all these coachwhips already here and I simply did not see them. Or is there some method that they attract eachother.
The most probable explination for that is, the cycling female is attracting a suitable mate and unsuitable followers. But that does not explain how they know to beg for food.
I have been thinking about this and somethings have crossed my mind. First, I rarely see coachwhips here, maybe a couple a year, over the last 25 years. But that does not mean they have not seen me. I may indeed be part of their landscape and they and other reptiles have been watching me, even if I do not see them. So in a sense, I am not new to them, and they have watched me for a long time. I am only adding something new to them that is benefitual to them. So they allow me to see them. They are just new to me.
Again your last paragraph maybe in fun, but that is not totally out of the question. Of course, they are not "talking"(are they?) but they may have the ability to use scent as a language. That is, they might be able to smell when others have fed, then follow their scent to that spot.
The point is, they are without question, four individuals coachwhips, of which, before last fall(2 then), have never been fed by me. Then starting the last day of april, four have come forth and have practiced the art of taking food from a human.
Again, consider the species. I also feed rattlesnakes. They come to the same spot about every third night and wait until I feed them, then they go to their holes which are some distance away. I have found those holes, but if I bother them to much, they move.
I have fed gophersnakes as well. The problem with them is they are gophersnakes. They live in holes and do not come out. So I have to go around dangling mice in front of holes. That gets tiresome after a few dozen feedings.
I also fed in a magisters spiny and had her for 8 years, I witnessed and photographed her growing up, feeding, climbing on me. Breeding with males, nesting, etc etc etc. She was "easy" as she would run me down and beg for food. I also did this with a roadrunner, I have the same pics, including her taking me to her babies. I fed them too. she lasted 8 years as well.
But COACHWHIPS, I guess once you get on their good side, they are just as nice as any other species. hahahahahahahahahahaha. The learning goes on. Cheers
