Raptors -- it's not just illegal, there's a fine up to a few THOUSAND bucks and up to TWO YEARS in jail, depending on the species and circumstances. You can get permits if necessary, but they are NOT always easy to obtain.
Cowbirds, crows, some blackbirds -- there are CFR (Code of Federal Regulations) regs that allow farmers to kill these birds IF the birds are in the act of depredation (eating crops or killing livestock). No permit necessary.
English sparrows, pigeons, starlings (non-natives) -- not protected at all.
