Avian vets don't go to Avian Medicine School, there is no such thing. All you have is Veterinary school and that covers ALL animals but you specialize in 'small' (dog and cat) or 'large' (farm). Avian vets, same as the ones that treat exotic animals (like the ones in the zoo) study on their own and practice under another vet. Avian vets need to work for six years under a board certified avian vet and then take an exam, if they pass it, they become certified themselves. They study for this exam with their text book of choice (Dr, Harrison, the one that makes the pellets, has several books written with other vets). I have three text books of my own (you can order them through Amazon and see for yourself that I am not making this up) and I can assure you that they don't cover parrot nutrition. They do cover avian nutrition but in a very general way (mostly related to deficiencies in terms of symptoms and such) because, after all, this needs to cover chickens, eagles, parrots, hummingbirds, etc. It would be impossible to cover it in detail because different species of birds eat all different kinds of things (nectar, pollen, insects, seeds, fruits, fish, mice, etc).
Harrison's pellets are traditionally sold by vets and the sales guys visit them (and talk them up) personally so, as they also make a profit when they sell you the product, they seem to be 'inclined' to recommend them more than any other diet.
I've had several arguments with avian vets about pellets... I even had an argument with Dr. Harrison, himself (about fruits making parrots fat). I once had a clutch of Timbrados that had been born perfect but had developed deformed beaks as they grew up (they were narrower than the norm as if a sliver was missing from each side of the top beak) and I took them to my AV - she did not know what could have caused it so she went on a site where only veterinarians can go to consult with one another, and nobody had an answer but one guy who claimed it was due to improper diet because the birds were not eating pellets. Now, if I had been somebody who had just bought a canary at a petstore, I might have believed this was the reason and immediately switched it over to pellets but I've been caring for canaries for over 50 years and have a bit of knowledge about them. And I know that canaries not only are natural seed eaters in the wild but also that they have been bred -and fed seeds- since the 1400's so how could seeds be bad for a bird that nature evolved to eat seeds and that has thrived in captivity eating seeds for hundreds of years?! It was ludicrous to say the least! They do need fresh food and they would develop deficiencies if only fed seeds but my canaries get a different leafy green every day as well as a piece of fruit or a vegetable (they don't get both, just one of them) and my canaries are not only healthy, they live much longer than the average (I had a hen that lived to be 18 and gave me her last baby at 10 years of age) so I knew this guy did not know what he was talking about and was simply repeating something somebody had told him - and he was an AV!
And it's like Victor said, there are good vets and there are bad vets just like there are good and bad teachers and good and bad plumbers - a degree or a certification doesn't make you infallible and it always pays to make sure on your own. Most especially when it comes to parrot care as we are only now beginning to learn the basics of it.
Victor, yes, African grays and tiels do have different dietary needs. Tiels are partial ground foragers so seeds are not as bad for them as they are for other species of psittacines (mine get gloop for breakfast and a budgie seed mix for dinner). In my personal experience, they are not big on fruits but they do love their greens and some veggies (corn, sweet potato, peas, chopped broccoli). Grays are hard to convert to a good diet and that's why the gloop is so useful.
