Young birds in my yard

I am not sure what these are. The top photo may even be different than the others. The one on the vehicle then flew to the short wall, so I know these are the same bird(s). These were Saturday afternoon in my front yard. We still have babies everywhere. Seems odd, with the leaves beginning to change already.

Eastern Bluebird

I originally thought she had 2 worms in her mouth, but now that I have the photos to examine I think she just has one, holding it in the middle. I used my husband's lawnmower's trailer as a blind so I could get a little closer today. I also think she may be feeding caterpillars to her young, cutting down on my butterflies. I guess that is part of the natural cycle. Just one I don't like.

Eastern Bluebird 'Mama'

I stepped around the back of Jimmy's shop and right in the garden is this Eastern Bluebird with a worm in her beak.She takes it to the top of the birdhouse her babies are in.
She goes back to the tomato stakes,

and appears to be struggling with this worm. She succeeds to get the worm back in control.

She flys back to birdhouse, and appears to be looking at me for advise.

She goes back to the tomato stakes, but either has swallowed the worm, or dropped it.

She finally turns around on the tomato stake to get ready to fly off.

I took 56 photos in 19 minutes, and then the show was over for the morning.
