As an avian vet I actually agree, mostly

. I don't think annual visits are necessary, especially for experienced parrot owners. I think new bird health checks are vital and you should get the full "service" then

- bloodwork, faecal check, crop check, physical exam, chlamydia test, beak and feather and polyoma virus DNA test. Bear in mind that this list of diagnostics will not pick up all diseases so any vet that guarantees that your bird is healthy after receiving normal results from these tests is stringing you along. Remember that injured kidneys need to be 70-80% compromised before the blood tests will even show that there is a drama, and sometimes a liver is so badly damaged that the liver results will tend to be in the normal range because the organ cannot produce the enzymes anymore...just as some examples of where test results aren't accurate. However, a young, healthy bird with no clinical signs of illness and all tests come back normal can be classed as healthy to the best of the vets knowledge (based on physical exam and test results).
A note on faecals: Just because your bird has an abnormal gram stain doesn't mean its sick as there are many bacteria that are ubiquitous in the environment that will just be transient through the gut. ALL gram stains need to be interpreted with clinical signs and in fact, I only ever do gram stains if a parrot is showing signs of gastroenteritis or other gut problems. Another note: Gram stains are only valuable in parrots...NOT in other species
Birds that are housed outdoors should have regular parasite screens which is as simple as sending a faecal sample to your vet every 3-4 months and doesn't require the bird set foot in the hospital.
Experienced owners will pick up on subtle sick bird look (SBL) signs and behaviour changes early enough to get their fid to the vet. Inexperienced owners may benefit from regular health checks until they become confident with picking up the subtle changes themselves.
We certainly don't recommend annual health checks where I work but maybe that's because we're a wildlife hospital that sees private patients on the side (that sounds very dodgy

) - the private patients help us fund wildlife treatments

and if anything, we charge too little because we're so used to doing free stuff for wildlife...sigh!
Another good idea (if you have a good avian vet nearby) if you're an aviary owner is to have regular aviary visits. That way the birds can be assessed at home where it is more relaxed and they're more likely to show clinical signs of illness if there are any.
There aren't many tests you can do at home unless you're trained and know what to look for. Things you can do include the usual, monitor behaviour, monitor weight, feel the keel regularly, check the droppings, make sure you know what is normal for your bird so you know when they're abnormal. Make sure the bird is eating (monitor weight or even weigh the food daily to check)...etc.
So yip, annual health checks probably not mandatory but definitely take your bird to the vet (an avian vet!!!) the moment it looks even a smidgen unwell...I know I'm preaching to the choir and the converted already

but that preservation reflex in birds is super powerful so often by the time the signs are showing they are horribly ill and immediately get downgraded to a guarded to poor prognosis and if the bird is sitting on the cage bottom and unable to perch then it is critical and given a grave prognosis for recovery.
That's my two cents worth
