Cleaning the House

I think this is bird poop that the babies handed up to her. She flew away with it after feeding the babies some insects. Any ideas from better birders than me?
Thanks for your visits, comments, suggestions, favs

I don’t know either, but it’s a cool shot.

So interesting.

Just read about these recently; they are called fecal sacs, sort of a baby bird diaper! Mucous membrane surrounds the poo making it easier to collect and carry away. Cool shot.

Great capture. Read what amyk posted and that is really something. Never would have thought that's what it is.

Yes, definitely a poop bag, most of our nesting birds carry it off too. Nature is so amazing!

Yes, it is a poop sac that is being removed. Isn't nature amazing?
