When Mom & Dad Away Are Eyas at Risk?

[DoggyMom]

I notice that at times neither parent is on the nest. I'm wondering if the eyas are vulnerable to other predators at those times.

After watching for a few hours yesterday morning, I can assure you that when one parent flies off, the other is very close to the nest box.  You may not see them on camera.  They don't leave it undefended.    

Oh, and congrats on your first post Doggymom.  Good question.
