1⃣ #ISTC20 #Sesh8 👋I'm a PhD candidate exploring #shorebird communication across the eggshell in Melbourne, Australia. Some avian embryos can begin calling late in incubation and can communicate with parents through the eggshell🥚Have a listen to these embryonic calls, below!
2⃣ #ISTC20 #Sesh8 Visual egg and nest crypsis is a common shorebird defence strategy but some predators may use embryonic vocalisations as an acoustic cue to locate these hard to find nests🦊
3⃣ #ISTC20 #Sesh8 We know that shorebird hatchlings rely on acoustic crypsis, hiding and becoming silent in the presence of a predator🐣 So, could this defence strategy begin prenatally and do embryos cease calling when exposed to signals that suggest a predator is nearby?
