Look at my new baby. She/he (don't know which so will call it a "he") is a baby bluejay that ended up on my kitchen floor via Dusty. I had just come in from feeding the chickens and heard a squawk. There it was, looking terrified as Dusty was getting all riled up and ready to "play" with it. I scooped him up, poor little thing. I inspected every part of and there were no wounds, but it wouldn't open its eyes; it was terrified.
I made a little nest for it in a round strawberry container with a handle after carrying him around for awhile. He sat on my finger comfortably and calmed down. I cooked some egg and cut up a strawberry and he chowed down... and eats about every hour. I hung the "nest" out on a tree limb so his parents could find him because they'd been flying around a lot. They kept coming close, but never approached him. I read that they will take over if you give them the opportunity, but with three cats hanging out on the deck, I think they must've thought the risk was too high even though it was a safe distance away.
A little while ago, after feeding the little fella again, he started acting all energetic, flapping his wings and getting a little cocky. He jumped up to the top of the strawberry container "nest" and started acting like he was going to fly. Hmmm... he can't even eat on his own yet; why is he thinking about flying so soon? I went in and got my camera and when I got back, he'd jumped up to a tree branch (as seen in the first picture). I shot his picture and the next thing I knew he flapped his wings aiming for the bluebird's house and fell - flapping the whole way - to the ground. He was fine, but I now have him in a little animal carrying case where he can't escape. I assume that is how he ended up on the ground in the first place when Dusty found him.
Hopefully he will keep eating and get big enough to fly and then take off on his own. That's the plan, though I have a doctor's appointment today and might be taking him with me since he can't go too long without food and water.
