Very beautiful snakes!! I have often speculated on the total diet consumed by ringnecks. I actually saw one try to swallow a green treefrog many times the size of the little snakes head when the two were in a jar together right after capturing. It had the whole leg up to the rear end down its throat!! I would venture they eat softbodied insects like grubs and crickets as part of their diet. I have read they also eat smaller snakes. They sound extremely opportunistic.
