Backyard bird watching

[FishermanTim]

I showed this to some coworkers, and they thought is was cool until I pointed out the dead animal (and bird) in the foreground.
Then they thought it was gross.
Exactly how did they think the eagles fed their chicks, with take out?

I can't tell, but has they parents taken turns? I would hate to think that something would have happened to one of them, because if anything did, the chicks would never survive.
I say that because these birds were the focus of a PBS nature special a couple years back, and other birds that were included in that show didn't survive when one parent died during the filming.
As tough as it is to do, they do follow a strict "non-interefernce" policy and they let nature take its course.

It looks like one of two things has happened to the thrid egg in the nest.
1) it's in the process of hatching, and since we can't make the bird move, we can only wait for the sitting bird to move for a chance at seeing the egg clearly.
or....
2) the chicks have taken it upon themselves to increase their share of food from the parents by committing fratricide and "offing their un-hatched sibling. (hey, it's "survival of the fittest"!)

I can't watch it all day long, and it seems that there's some new carcass in the nest each day.
