No, it doesn't sound silly, it's a very reasonable question!
There are not many vet clinics that are exclusively avian-oriented, but if you have one near you, they are always your best bet. The link below may help you to locate on near you...
Many other vet clinics who say they do exotics may see reptiles, even sometimes amphibians or fish, as well as birds. Most have dogs and cats as their main clients but may also have an avian vet on their staff - you can generally tell by the information on their website which one of these variations might operate at the clinic near you. If you are lucky enough to have an exclusively avian vet close by, they would be your first option. But I know of some VERY good bird vets who operate out of other, more generalised clinics as well
