And I finally have an answer for you!!!! What a fascinating question!
Rabies can be experimentally induced in both domestic and wild birds.
It does not occur in nature.
The owl has been known to develop antibodies to rabies (just as a mammal
that had been immunized would).
In examining 343 birds, 23 (6.7%) were found to have a low passive
titer. This means that they would be classified similarly to mammals
that carry but do not develop rabies in the classic sense. The majority
(but not all) of these 23 birds were raptors.
Theoretically, a bird could pass on rabies by talon or mouth.
No cases have ever been reported!
It is speculated that body temperature might be involved. But, the
types of receptor sites may also play a role.

This increases my belief that dinosaurs were not susceptible to rabies
-- or any of the related viruses.
Oh, and I was essentially right in what I thought!
