I've read some of your other posts. Fish, reptiles, amphibians and birds all learn to avoid pain (physical), therefore they perceive pain. There are several other indicators for the perception of pain. I'd consider that "painful" sentience. Maybe they don't "feel" (experience) it the same as humans but they do feel it.
Google Pain in "........" wiki. Then read.
And after that, ask yourself why veterinarians administer analgesics to a wide variety of animals, including birds.
