 We found that a tiny songbird mimics the alarm calls of other species to deceive predators attacking their nest. Mimicking so-called hawk alarm calls of other species, which normally signal that there's a very dangerous predator nearby, which the predator attacking the nest itself is also vulnerable to. The main nest predator in the Botanic Garden are pied carawangs, which are a crow-like bird that are voracious predators of nestlings. They eat literally kilos of nestlings that they feed to their own young. We set up an artificial nest and trained carawangs to come in and feed from pseudo-nestlings, pieces of chicken meat. And then played back to the Thornbill parents' calls when they're about to take another piece of chicken. The predator firstly pauses, looks around, and then sometimes even flies away. In the meantime, the nestlings have an opportunity to flee the nest and hide in bushes nearby. When I was taking a group of undergraduate students on a totally unrelated project where we had a stuffed owl in the bushes here, and I kept hearing the sounds of birds that I couldn't see, and eventually I realised that it was a brown thornbill that was mimicking the calls of a variety of other species. We have a tiny bird, maybe seven grams, which is deceiving a monstrous predator 40 times its size. And it's really doing so through cunning, and obviously it can't physically match a carawang, but it manages the defeated, if you like, by this nefarious strategy of lying to a predator.
