I have been keeping cockatiels since about 2001.I've finished work and had time to read every ones posts.
Thanks to everyone who gave their option, there was interesting info in there and bare with me as I try to address your points.
First of all as some of you pointed out not all parrots are granivores. Thank you chris-md I didn't even know there was such a term.
I'm talking about these granivore parrots and the idea that one should not feed them seed at all because it's somehow bad for them.
It was interesting to read about human grade and animal grade foods. Thanks to sailboat for that info.
Sailboat also mentioned the possible conflict of interest that our vets may have. I hear ya. That was in my mind too.
All in all most of us are in agreement that a granivore parrots should eat at least some seed. A balanced diet is preffered. Im not anti pellet. With my birds I always have seed mix with pellets on offer. They hardly touch the pellets, they seem to know its fake food. Their favourite other foods are bread, rice and potato.
Their weight is always within a few grams which is why I don't think they eat as much as they do in the wild where they fly more and have to eat more. I've seen huge and small flocks of different types of cockatoo foraging in the ground for hours while I'm fishing and watching them. They sure eat heaps more in the wild.
I know of granivore parrots living to old ages in captivity eating a seed based diet, so this claim of fatty livers is not in line with my many personal experiences and observations of my granivore birds and that of others.
Some people (not on this thread, other people) take this "fatty liver" claim and just say "it's fattening" for their bird so they only feed them pellets.
I see how the misinformation I heard actually came from this other fatty liver opinion to begin with now.
Anyway thanks again to those of you who gave some food for thought on this topic
they have been on a seed/pellet food mix the whole time.
I never had much luck getting them to eat veggies or fruit.
Igive them 1/2 inch chunks of millet seed 2/3 times a week.
The pellets they eat (and they really do eat them) is Zupreem nut blend (large bird size)
it”s real cute watching them hold the pellets in their feet and munching away.
I lost one of my female Tiels (Sunny, mother of two clutches of babies) due to a liver disease?/failure?.
It was not fatty liver but she died on a 3 day holiday and a full necropsy could not be performed.
IMHO I think that fatty liver is more species specific.
I mean I know Amazons are susceptible to it and it’s something I worry about.
Those are the birds I have (and my African Grey) and so they are the birds that I have looked at most closely as far as diet goes.
You have parrots like lorikeets that eat lots of nectar.
And well there is lots of variety out there.
as stated above it’s not a one size fits all.
