Mojo, partic. when cruising outside often jerks his head from side to side, often prior to moving. I have seen this before in other colubrids, partic. the coachwhips & have read somewhere that w/ lizards...they are doing it to achieve better binocular vision. I suspect it may also have to do w/ a defense strategy where if a predator makes a play, a moving head is harder to hit & if you dont land on a snakes head, you pay a price! In any case they seem to be in max alert mode when doing this. The neck distension is very interesting & clearly related to defensive display.
:I had been keeping my 2002 female eastern in a medium sized rubber maid (about the length of her body)with a heat tape running underneath. The tape was regulated to around 78 degrees but there was not really a "hot" spot for basking. I've recently moved her into a considerably larger cage & she seems more active although she still spends the majority of her time in the hide box at the cool end of the cage. However I am now offering her a heat rock which is regulated to about 88 degrees & she does seem to utilize it. Tonight when I walked into the room & found her regulating on the rock she did something i've never seen her do before. She raised her head & bagan slowly waving her head & neck back & forth. At first I though Oh No, she's gonna regurg! After a minute or so she stopped doing this & began flicking her tongue in that alert/aggressive mannor & started cruising around the cage with her neck flattened out. Now, i've heard of the neck flattening in an agitated indigo but, i've not heard of the head waving. Is this something you guys have seen in your snakes? Do you think her new found attitude has to do with her new surroundings? Was I perhaps keeping her too cool before?
:I'm not concerned, just curious. Thanks for your input!
