Baby sparrow dead overnight

[Albi]

On July 3rd I rescued a baby sparrow that had fallen from her nest. No trace of her parents whatsoever. I took care of her until yesterday. She was a very docile, sociable and intelligent baby sparrow. I fed her with the food that was recommended to me by an specialist and until the last moments she ate normally and her droppings were normal too. One thing we always noticed about her is that she scratched her wings and body in general insistently, roughly. We bought a product for the mites just in case and tried to sprayed it carefully over her body and wings (just once a week according to the recommendations) she was also very likely to fell asleep almost anywhere during daytime. Her last two days ...we noticed that she ate as usual and her droppings weren't abnormal but she would fall asleep easily. These last two days her chirp was different too, it was weak. We also noticed that she lots some feathers on her left cheek. She would follow me around the house looking me in the eyes as if she was asking me to "pick her up" with my hands. She would allow me to kiss her and caress her. Whenever I called her she came jumping very fast. Everything seemed fine so far with her and just like that she died. It happened yesterday overnight. I feel very sad. Helpless. I loved her so much and I still do. I don't know what went wrong? I feel guilty of her death even though I know that she was very well taken care of. We loved her and we know that she loved us. We never put her in a cage. She was free to roam the house and also our garden (she didn't fly even though she was almost 2 months and a half old. We always thought it was because she was comfortable with us but I might've been because she was sick all this time and we didn't know). I tried to give her the best life she could possibly have for a baby sparrow. That's the only comfort I have right now. Thanks for taking your time to read this.

 

The last  picture is from the last week before she died. The first one was taken a week or two after we rescued her.
