if one bird can eat it, then it's fine for all birds
I used to be a member of a quaker forum and used to ask questions on it to see what my quaker can eat, and wanted to make sure it was safe for all birds since at the time ijust had quakers and a couple budgies -but i did find out if one type of bird can eat it they all can - which makes it much easier when you've got multiple species
not quite true... we have lorikeets here and you cant give them seed..
Lories are physiologically different than other parrots and are designed to consume a diet of nectar, pollen, fruit, bugs, small lizards and such. Their brush tongue is perfectly suited to the gathering of this nectar and pollen. Their ventriculous, or gizzard, is less muscular than that of other parrots therefore they should not eat the type of hard, dry diet we feed our other parrots.
stuff like budgies, tiels and quakers are all 'parakeet' type parrots, and therefore, what is good for one, is generally good for the other...
