In the news..Crock ...of eggs
Here's a news story in which I insert myself as tho I really were involved:
Again, like the research recently of COFFEE SMELLS...pretty much stupid money...
Do we REALLY need research to tell us what a CROCK eggs does? Ok..Maybe its NOT all a crock...of you know what...anyway...read on dear one reader:
have known that shortly before hatching, crocodiles make noises within their eggs. A new study
Biologist noted BEFORE KRisscop gaining exposure through Krisscop's House blog, which involved playbacks of the pre-hatching calls, reveals these calls from the egg tell siblings it's time to hatch and tell moms it's time to uncover the nest. As a mother of three hatched urchin herself, Krisscop can attest to the fact that young ones FREQUENTLY make noise, and tell siblings where to go.
Researchers Vergne and Mathevon , with little or no input from Krisscop of the Jean Monnet University in France monitored Nile crocodile (Crocodylus niloticus) eggs that were due to hatch within 10 days. The eggs were placed into one of three groups, for which the researchers either played recordings of pre-hatching calls, recordings of noise (other than the calls), or no sound.
The group of eggs that got a dose of real croc calls responded and moved, as the about finger-sized babies jostled about, more often than the "noise" eggs. The eggs incubated in silence showed no movement. Krisscop wonders if this noise made them mad because their nap was going to be interrupted...
All four of the individuals that successfully hatched in the croc-call group did so during or within 10 minutes of the playbacks.
After the eggs hatched, the moms-to-be stuck around to continue their nest guarding.
Krisscop later noted that "moms" pretty much are ALWAYS the one that continue to stick around.
The researchers found the female crocodiles responded to pre-hatching playbacks coming from loudspeakers hidden underground near the now-empty nests.
The female adults more often turned their heads or moved after egg sounds than after noise.
