Bird my dad found!!

Ok, so it's not a pet..but he's so cute!!

My dad found the bird cuz our cats were trying to get to him, we held him a little but put him outside kind of away from our yard so cats hopefully don't get him. :)

But I believe he's a house sparrow? I'm unsure.

But he's a fledgling, perfectly ok, no injuries that we found.

That was my first time ever holding a living bird!

Also..PLEASE give me tips on how to put a bird in resin(is that possible?), or for taxidermy! I have a couple dead birds I found that I would like to preserve, I love birds and I just want to appreciate them by preserving them.
