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?

1 #ISTC20 Low reproductive success threatens long-term viability of many #shorebird populations. Hooded Plovers (aka hoodies) are highly threatened #BeachNestingBirds along AUS southern coast and impacted by threats like human disturbance and introduced & superabundant predators.
2 #ISTC20 Threats’ impact on egg & chick survival is poorly understood. We set up remote-sensing cameras on 81 Hoodie clutches along the Victorian coast to confirm nest fate, and radio-tagged 27 Hoodie chicks (from 27 broods) to monitor survival and determine causes of mortality.
