Developing a taste aversion in goannas - what will they think of next?

Tweet

I’ve written from time to time about pests introduced into Australia. One of these is the cane toad which was introduced to try to control infestations of cane beetles in Queensland. The cane toads found conditions to their liking and have spread across the north of Australia and into Western Australia where they’re making their way down our coast. They have a poisonous gland on their head and native marsupial and reptile populations are being decimated by eating the toads. In an effort to develop a ‘taste aversion’ in goannas, hundreds of toad eggs are being released in significant areas. The idea is that goannas will eat the young toads and become sick. They won’t die but will develop an aversion to eating the toads when they recover. Let’s hope it works. The photo is mine. I'll spare you a photo of a goanna and just give you a landscape.
