Actually, what you will find is that most birds are protected from hunting, trapping, or otherwise harming. Some are limited in being able to do them in, limited by season such as duck season. Some are always protected all the time. It is easier to compile a list of unprotected birds than protected. For example, the european Rock Dove or what we commonly consider as a typical city pigeon isn't (or used to not be) covered. Same with the european house sparrow, but other indigenous sparrows are protected.
Art may be correct that there are limited circumstances when some types maybe done in, but I can't remember any specific instances that currently apply today. Of course, it is been about 10 years since I was up on the specifics of all said laws that I had to know for having a scientific collecting permit in order to procure specimens for a university comparative collection. I ended up getting a salvage permit to collect specimens not intentionally hunted such as roadkills, powerline kills, and natural deaths. It was not a sexy job.
