Defense level verses propensity to eat

chuckhurd May 18, 2009 06:44 PM

Last night I feed my very sizeable collection of south eastern pit vipers. Of the 70 or so snakes that were offered food, only 2 did not eat. The two that refused are the two most defensive snakes in my collection. Both get into a defensive posture anytime anyone is in the room. Both strike anytime their tub is pulled from the rack and both fight being moved and run anytime they get the opportunity. On the surface one would think these two would be quick to attack anything placed in their tub, but that is not the case. My observations led me to believe that the more defensive my snakes are toward me, the less likely they are to feel secure enough to attack and eat prey items. The two in questions are both very large. One is a captive raised female western cottonmouth, east TX locality and the other is a one year captive male canebrake rattlesnake, northern AL locality. The cotton did not touch the mouse. I later removed it and gave it to my female FL cotton. The cane killed the rat, but did not eat. I removed it and gave it to my large female canebrake. Both of which made quick work of the extra food. I do not engage in any type of animal fighting, but I know people who do both rooster and dog fighting. Being ignorant to it, I assumed the best fighters would be the hardest for handlers to control, however, both tell me that if an animal is aggressive toward people, they are worthless fighters. I see a correlation here. If the fighters are concerned with the people around, they do not focus on the other animal. If the snake is concerned about the people around, it is less concerned about the food animal. Or, at least that is my contention with my south eastern pit vipers.

Has anyone noticed this trend in other species?

Well, moving away from venomous, I have a 5-ft Texas rat snake (WC) who has retained the renowned "don't mess with me EVER!" behaviors common to his species, but he is an easy feeder on F/T and live alike. Thing gets whiplash snatching that rodent from the tongs. He's even quicker than the very lad back corn snake in the next cage. I wonder if a habitate adjustment might help -- you note that these are both sizable snakes, could be they feel cramped in a tub arrangement.

In my experience if a snake is overly defensive they are also a little stressed because of it. So it just goes back to....a stressed snake doesn't eat as well as a non-stressed snake.

I like that you are observant of your snakes, even though having a sizable collection. A couple of interesting points, the same behavior observed from one snake captive raised, and the other wild caught so that’s not really a factor. The reactions are based on something other than hunger. I think it’s really just the individual personality of the snakes. You can see that expressed even in a clutch of hatchlings from the same parents. Some will eat before their first shed, and some might refuse food and die. Ditmars use to really describe habits for each, usually spot on, but haven’t we all seen the “garter snake that thinks he’s a bullsnake…” or something like that. Just when you think you’ve got it down, something comes along to mess with you. Keep noting a sharing your observations.
