I was wondering the same thing. Maybe not?! I know coyotes have been known to not only kill new born calves when they hit the ground, but go right in and start tearing at a calf as the cow is having it...and tear up the cows nether regions while they are at it. This is not just a second hand story, I have witnessed it first hand, and spent a good bit of time shooting them during calving season back before we retired and still had cattle, horses and sheep.

Anyways, be interesting to find out if dingoes display similar behaviour. I am sure some of the ranchers on this site from Down Under will be able to speak to it.
