The blue birds have a nest in the purple martin house. I guess that is okay as the purple martins don't come to my house to use it. Anyway, this morning they were having a fit. Some starlings were at there nest. Now of all the holes in the purple martin house, one starling was looking in the hole where the baby blue birds are.
The blue birds were in the tree squawking. I thought I would have to shake the pole the get rid of the starlings, but when I walked out they flew off.
This afternoon I saw both of them with bugs in their mouths to feed the babies. I ran back to get the camera; too late, already fed them.
I haven't seen the cardinal anymore building on the nest. Maybe she abandoned it; fiddle.
