Radisson - 2011 / Ivy & Princess
The Peregrine Chick:
1831 hrs
I'm not trying to get anyone's hopes up but there is a suspicious small dark spot on one of the eggs which could, just might, perhaps, maybe be a pip. The egg before it disappeared back under was closest to the camera and the discolouration was higher up on the egg, sort of where I would anticipate seeing a pip ....
Will have a look at video a bit later and see if there is a better image though I doubt I will see much better than we are seeing right now ...

Thank you TPC it certainly does help. As usual a clear easily understood answer . sg

Depends on what you mean by prematurely ... do you mean the egg is cracked from the outside and the chick can't stay inside anymore so has "hatched" or do you mean hatches before our estimated hatch date?
Unlike mammals where the mother plays a role in delivering infant, the chicks are the ones who do all the work in this case. Can't say that an egg in a wild nest that accidentally broke at 25 days (rather than 30) hasn't ever survived because stranger things have happened. Having said that, chicks go from a spark to a chick in 30 days so even a few days early is a huge deal in terms of development - I guess a rough estimate for demonstration purposes would be that 3 days of chick development is equivalent to 1 month of human development. So hatching 3 days early could sort of be like being born a month early.
If you are asking would the chicks be in trouble if they hatched today, the answer is no. We used to have nests that hatched out consistently at 28 days (Madame's nests) and no muss, no fuss - Trey turned out all right after all.
Hope this helps :)

Don't know about whether or not this ever happens with peregrine falcons, sheltiegirl. TPC will answer that question. But I do know that apparently one of Phoebe the hummingbird's chicks from her last clutch hatched prematurely and then was accidentally bumped out of the nest by Phoebe and fell on the ground. It was returned to the nest and then was retrieved and placed in rehab but did not survive. :(
