Some avian embryos can begin calling late in incubation and can communicate with parents through the eggshellhttps://abs.twimg.com/emoji/v2/... draggable="false" alt="🥚" title="Ei" aria-label="Emoji: Ei">Have a listen to these embryonic calls, below!

Late term eggs of #RedcappedPlovers and #MaskedLapwings were exposed to a range of pre-recorded bird calls for 3 minutes while I documented embryonic calling
