Question?? bluebird babies

[Leandz 5]

I have a question 

 if all the blue bird babies  don’t leave the nest with the others do the parents still come and feed the one still on the nest ?

Hi Leandz, 

I read an article that said older bluebird siblings will help with feeding the young.  Now I have evidence of this.  I took a picture of a juvenile bluebird carrying a worm into the nest.  The yellow part of the underdeveloped mandible can be seen in the picture.  I am not sure if all of the juveniles stay at the nest or how long they stay.

I have seen the older and more mature bluebirds flying into the nesting hole.  I assume these are the parents.
