QUESTION?

Could this bird have the capability of flying off with Sadie Mae? Sadie was a light weight, perhaps two or three pounds...

I believe this bird to be a hawk, what species I am not sure...this bird has been hanging around (high in the tree tops and also in the field) since early July...There has been absolutely no trace of Sadie Mae, it is as if she simply vanished into thin air...Any information and or advice would be greatly appreciated...thank you...
