We had the same situation. Our cat got two of the three birds the mother was scared off. We kept the bird in his nest after we put it in a weaved garden basket up off the ground. We fed him raw ground beef, found grubs, and we gave him worms. It isn't okay to keep wildlife so we called the wild animal protection group and they took him and adapted him to a new environment. You can try to do the same.

Hope I helped!

Even though you had kind intentions, moving the nest was a bad idea. It was not your nest to touch and even if the mother is still around, she won't come back to feed or care for her babies because humans have touched the nest. If you aren't willing to save the babies then they will die for sure either from starvation,cold, or being eaten by something else. If you want to save them,take them into your home and put them in a safe place. Go on the internet and look up everything you can about taking care of wild baby birds. Or you can take them to an aviary or give them to someone who knows how to take care of them. If you arent willing to do any of that then they'll be dead within a week

To be sure, put a baby gate or puppy gate all around the nest, and put some blankets on the bottom. As long as its up high enough and you do this, I think they will be ok.

We found this nest in a small little garden, filled with 3 birds, I think they might be bluebirds, one baby bird was found by my dog :( but the two other baby birds are still alive, we moved the nest to higher grounds but I'm worried about raccoons, cougars, bears, dogs, cats and other animals finding them and killing them. I was also wondering if other types of birds like robins or hawks would kill them? I think the mom might still be around but not positive! I really want these guys to survive so any advice on caring for birds would be great thanks
