If any babies fledged it will be considered a successful nesting! If I were you I would monitor more closely. Good notes can help you determine what may have happened. Blowfly feed at night and as the other babies left they would have had only the one chick left to feed on. I'm not saying that's what happened but it is a possibility. I know we are not supposed to interfere so much but I would have tried to at least pick the baby up to be sure it was not stuck on something and examine to see if there was something obvious that was keeping it from leaving. I did have 3 TRES babies that just were not strong enough to fledge (due to loss of a parent and bad weather). It is sad but sometimes there is not anything we could have done and it's just Natures way. Good luck on the next nesting!

I know Ann I could sit and watch these beautiful birds all day, my Ma Ma Blue just built her second nest yesterday I'm so excited about a second nesting....and the babies from the first fledging are now coming out of the trees and sitting on our patio and wires behind with the parents. I'll be watching your posts to see how your second group does good luck.

Ohsoblue I will be pleasantly surprised if we get another nesting, but it could be in one of the neighbors yards, as they have all put up boxes, but I do not think they monitor very well. If they do come to our yard, I hope they choose the other box, as we have a camera in it. Mine are still coming back for meal worms, but the worms are just about gone and I doubt I will order more, unless I see a nest being built. It has been fun.

Bluebirds are drop feeders, they perch on something and watch the ground for movement and drop down on it to catch the bug...how do you plan on teaching this to the baby bird? With rehabbers they normally have other birds that can teach nestlings how to hunt. They also try to release a bird they took back in with the same family group or another family group. I can understand how you become attached to the bird but it isn't good for it, rehabbers understand this. As far as cats...GOD did not put domestic cats on this earth to hunt and kill...he put wild cats out there to do that. Man domesticated the cat and it has changed greatly over the years...it no longer belongs outside to kill just for the fun of killing...most house cats let outside don't eat what they kill they just kill. I just cannot understand people that love birds yet let their cats outside...doesn't make sense. Dog owners are expected to keep their dogs on their own property and leashed when off...why do cat owners feel they can let their animals out to crap on other peoples lawns and sandboxes...I just don't get it! One of our neighbors has a cat and she does let it outside however it is always on a tie out when outside...now that is a responsible cat owner that cares about her cat! Maybe if you would have had your cat on a tie out or in a outside kennel made for cats you wouldn't be in this predicament. Seriously if you must let your cats outside...please take down any bird houses you may have, it certainly isn't fair to the bird that may nest in your yard to have to live around a cat...fledgling time would be especially dangerous as many fledglings cannot fly well at first.
