brooding behavior in ratsnakes?

shelley7950 Feb 03, 2005 09:35 AM

I just bought a copy of "Snakes Alive: and how they live" by Clifford Pope (favorite childhood book; love Pope)...anyhow, there's lots of now funny outdated information (like the latest theory that pitvipers somehow "hear" through their pits), but lots of stuff that's still true today...under the section on "Reproduction", Pope says:

"In the vast majority of cases only the female attends the eggs, but the male may also take part...In Pennsylvania Oliver P. Medsger noticed...two pilot black snakes...that would alternately lie on a pile of sawdust and bury themselves in it. When removed to a distance they always returned. After 3 weeks Dr. Medsger dug into the pile and found the male coiled around 44 eggs. As suggested by their discoverer, it is quite possible that the snakes were carrying heat to the eggs by first sunning and then coiling around them."

Is this possibly true? Has anyone seen brooding behavior in ratsnakes, or any brooding behavior by males? Just wondering...thanks for any input...

Yes, if finding a snake wrapped around a clutch of eggs and defending it can be called brooding, I have seen it, numerous times. Last summer a female Chinese beauty snake, Orthriophis t. taeniurus, wrapped around her freshly laid eggs and I had quite a time getting them out for artificial incubation w/o getting a lacerated hand. This was the second summer I observed the same situation with her. Also, most of my other Asian ratsnakes are found wrapped around their clutches after delivering the eggs. I think it's mostly defensive and not for incubating, however. They don't seem to increase the temp of the nest box, and rarely leave it.

In the wild, I remember one noteable event of brooding. My brother and I found a large, female, Eastern hognose snake inside a rotting tree stump, and she was wrapped around over twenty eggs. This was many years ago and I don't remember many details, however. It's possible she could have just delivered the eggs. I've seen many snake clutches in the wild that didn't have any parent around.

My Taiwan beauties have always coiled around their eggs after hatching..

However I doubt the males would ever trade off with the girls.. But thats just my 2 cents.

My Blue Beauty snakes also coil around the eggs. The female will leave them for a short time, to eat or drink, but then coils back around them until they hatch, unless I remove them for artificial incubation.
