No. A squirrel is a mammal, and a rodent like rabbits and mice. There is a type of squirrel called the flying squirrel, but it glides rather than flies.
No blackbirds would not eat a squirrel.
Are you sure you're not talking about a flying squirrel? They don't fly, but they glide. I don't think there is such thing as a half bird, half squirrel. If there is, combine bird and squirrel. (Squird or Birrel or something)
A squirrel eats a berry, a bird eats the squirrel, a turkey eats the bird, and a human eats the turkey.
No even though it can fly the Flying squirrel is not a Bird it is a Mammal.

Because it needs food, the squirrel may be in its territory or it may just be naturally violent.
