Now I can speak for the larger species not for
BCC but yes there are publishings about this and hopefully more to come.
Taxonomy, Life History, and Conservation of Giant Reptiles in West Kalimantan and was written by Mark Andre Auliya. is a great example, I am trying to get my hands on some other published material I was told to wait patiently and a new book may be coming out about this very subject.
A few of the retics trapped in Marks studies did regurgitate but odds are it was from being trapped and not from over eating. The majority of gut content were rodents so meals are frequent there is no shortage of rodents and if 10 foot snakes can get bellies full of them there are plenty to go around.
Another good example is the amount of aggravation it takes to get this Anaconda to throw up. Granted idiots mislabeled it but you get the point.
Now if you would like to ask my sources I can give them to you but there are publishings out there and articles out there.
