Ocean is sooooo pretty!!! I know that most people think that cinnamons and pineapples are pretty - and I am not saying they are not!- but I find the pale beak unattractive compared to the black one and I prefer darker colors than pale ones [I've never been a 'pastel' kind of person
]
As to Irwin, I would not take him to the vet. I take ALL my new birds to the vet for a complete wellness checkup but, unless it shows something like super high bile acids, CPK or BUN, I don't take them back unless they show symptoms - I don't even take the old ones every year. The truth of the matter is that, aside from getting antibiotics, antifungals, parasiticides or anti-seizure medicines there is little else a vet can give you that would actually be any good for the bird. Of course, that is just my personal opinion, based on my personal experience and I am completely sure that every single avian vet out there will deny this. But, the way I look at it is that taking them to the vet is EXTREMELY stressful to them and, as stress kills more birds than anything else, it seems to me that giving them extra stress is the wrong way to go.
The way I look at it, if nothing was severely out of whack on the initial bloodwork, the bird is showing no symptoms and appears content PLUS it's getting enough exercise, as little stress as possible under the circumstances [captivity!], a good, fresh food diet, a solar schedule and, if the bird's condition and/or advanced age require it, natural supplements nothing else can be done for it so taking him to the vet is actually more detrimental than helpful.
