That is an adorable baby bird. I'm quite certain it is not a Bluebird though. As for age, here is a link to a page that has images from egg to fledge (Eastern Bluebirds). Please post another picture as the baby grows. Maybe someone will be able to identify what kind of bird it is.

Kendra2,
thank you so very much for that link!
I've had her for over a week and that means she/he should be flying soon :)
The parent birds were definitely blue birds. I know sometimes other birds lay eggs in others houses, but this one has blue wing feathers when he/she stretches the wings.
Yahoo! it might be ready to fly in time to migrate.

If you let that baby bird go it will certainly die...it will have no clue how to hunt for food without learning from its parents, nor will it know to migrate unless it joins up with a group of bluebirds. It needs to learn to hunt for food on the ground by perching and watching for movement. Poor thing....cats should be indoors period...they should not be outdoors...they kill too many birds.

dzyg,
I started taking her outside when my cats are inside. She hears the other birds and intently checks out everything around her. She tracks bugs with her eyes but makes no attempt to feed herself.
When I feed her I show her the bug 1st and she gets excited but just acts like a baby. lol
I put her on the ground and she jumps at me. I know her parents wouldn't be letting her out of the nest just yet but I'm trying to get her used to the outside world. She enjoys stretching her wings in the sun.
I know a lot of people agree with you on keeping cats inside. They are natural born killers. But that was Gods plan for them. So I respectfully disagree.
I do absolutely HATE that they kill birds. That's how I got into this predicament. :(

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.

I've had her for just over 2 weeks now and she is flying really good. ( just in the house) She still isn't feeding herself but she has started to peck a bit at the meal worms.
I've turned off the heat mat to acclimate her to the colder weather. So far so good :)
As soon as she starts eating on her own, I plan to put her in the screen house set up on the lawn and see what bugs she can catch. Of course I'll "salt" the area with meal worms and poke berry branches. Just during the day and bring her in at night.
I still haven't heard back from anyone but you all here. Oh and more good news, her beak has turned hard and dark. She hates the dog food mush now and only eats berries and bugs. I tried making the blue bird suet and she has no interest in it yet. :(
Thank you all for your input and advise

I had to call the heck out of a bunch of rehabbers to get any response for my baby treeswallows. I didn't rely on email. You can also call animal shelters and nature centers for rehabber names. Sounds like she's doing real good tho.
