Interesting question, Ellie, because I was actually wondering the same thing. So thanks for your attempt to answer Ellie's question, TPC because you also answered it for me as well as others, I am sure.

The Peregrine Chick:
It can be one or the other.  The adults do remove deceased chicks (depending on size in my experience).  I have heard anecdotally of dead chicks being fed to siblings but I've never seen anything like that ... and my question would be, if a chick dies, would an adult trust feeding it to its siblings.  That and peregrines don't practice siblicide or infanticide so I'm not sure it's a normal response to cannibalize their own young - but I admit its just outside my area of knowledge/experience.  As for outsiders removing chicks, I've done it before - both before and after we had the FalconCam.  I can't think of any other times that a chick was missing from the nest without my having removed it from the box.

Know that doesn't really answer your question Ellie, best I've got for you though ....

Clara & Esteban Colbert are in "hard" incubation at this point.

What exactly is meant by "hard" incubation, TPC?  ???

--- End quote ---

peregrines don't begin incubating typically until the second last egg is laid.  If it's colder they may start an egg earlier, a little warmer/hot maybe not until last egg laid.  Hard incubation is when the eggs are being incubated 24/7.  If very warm, even during hard incubation incubating adult will get off the egg for short periods of time.

Awwwww, that's really sad.
